In addition, in the following description, by depth direction (quilt when checked people is measured of subjective formula optometry equipment The fore-and-aft direction of scrutineer) Z-direction is used as, will (the left side of checked people when checked people is measured vertical with depth direction Right direction) plane on horizontal direction as X-direction, by vertical direction (checked people's when checked people is measured Above-below direction) illustrated as Y-direction.In addition, R, L for being attached to label below represent that right eye is used, left eye is used respectively.

For example, the subjective formula optometry equipment (for example, subjective formula optometry equipment 1) of present embodiment possesses subjective formula measure list Member.Moreover, for example, subjective formula optometry equipment possesses objective type determination unit.Moreover, for example, possesses control unit (for example, control Portion 70 processed).

For example, subjective formula determination unit subjectively determines the optical characteristics of tested eye.For example, as subjectively being determined The optical characteristics of tested eye, eye ametropia force (for example, spherical degree, astigmatism degree, scattered optical axis angle etc.), contrast can be enumerated Sensitivity, binocular vision function (for example, strabismus amount, stereoscopic vision function etc.) etc..

For example, subjective formula determination unit possesses projection optics system (for example, projection optics system 30).Moreover, for example, throw Optical system is penetrated to project sighting target light beam to tested eye.Moreover, for example, subjective formula determination unit possesses correction optical system (example Such as, optical system 60, subjective formula measure optical system 25 are corrected).For example, correction optical system configurations are in projection optics system In light path, the optical characteristics of sighting target light beam is set to change.In addition, for projection optics system, it is not necessary to determined in subjective formula The structure for the device for possessing projection optics system is integrally provided or separately set in unit.That is, it is used as this embodiment party The subjective formula determination unit of formula, can be the structure at least possessing correction optical system.

For example, projection optics system has the light source projected to sighting target light beam.Moreover, for example, projection optics system Can have will carry out at least one of leaded light from the sighting target light beam of the light sources project projected to sighting target light beam to tested eye Optical component above etc..

For example, it may be the knot of the light source projected to sighting target light beam is used as using display (for example, display 31) Structure.For example, as display, LCD (Liquid Crystal Display, liquid crystal display) or organic EL can be used (Electro Luminescence, electroluminescent) etc..For example, show bright polycyclic (Landolt ring) sighting target etc. in display Check sighting target etc..

For example, as the light source projected to sighting target light beam, light source and DMD (Digital can also be used Micromirror Device, DMD).Generally, DMD reflectivity is high and bright.Therefore, with having used using inclined The situation of the liquid crystal display to shake is compared, and is able to maintain that the light quantity of sighting target light beam.

For example, as the light source projected to sighting target light beam, it with sighting target is in current visible light source and sighting target that can be The structure of plate.In this case, for example, sighting target panel is the plate that can be rotated, there are multiple sighting targets.Multiple sighting targets include example The eye test sighting target such as used when subjectivity determines.For example, eye test is prepared with regarding for each eyesight value with sighting target Mark (eyesight value 0.1,0.3 ..., 1.5).For example, sighting target panel is rotated by motor etc., sighting target is guiding sighting target to tested eye Configuration is switched in the light path of light beam.Certainly, as the light source projected to sighting target light beam, can also use said structure with Outer light source.

For example, correction optical system be change sighting target light beam optical characteristics (for example, spherical degree, the cylinder number of degrees, cylinder In axle, polarization characteristic and aberration amount etc. at least any one) structure.For example, the optics as change sighting target light beam is special Property structure, can be control optical element structure.Can be saturating using spherical lens, cylinder for example, as optical element At least structure of any one in mirror, crossing cylinder lens, rotating prism, corrugated modulation element etc..Certainly, for example, as light Element is learned, the optical element different from the optical element of above-mentioned record can also be used.

For example, correction optical system can by optical change position of appearing of the sighting target relative to examined human eye (presentation distance) corrects the structure of the spherical degree of tested eye.In this case, for example, as optical changing sighting target Position of appearing (presentation distance) structure, can be the structure for making light source (for example, display) be moved along optical axis direction.And And in this case, for example, it is also possible to be to make the optical element (for example, spherical lens) of configuration in the optical path along optical axis side To mobile structure.Certainly, correction optical system can also will be controlled the structure of optical element and make configuration in the optical path The structure that the structure that optical element moves along optical axis direction combines.

Can be that the optical element at the moment configured in tested eye is switched over to match somebody with somebody for example, as correction optical system The optometry unit (phoropters) put.For example, optometry unit can be following structure：With by multiple optical elements The lens disk on same circumference and the driver element for making lens disc spins are configured, and by driver element (for example, electronic Machine) driving and electrical resistance ground switchable opticses element.

Can be for being led from projection optics system by sighting target light beam to tested eye for example, as correction optical system Optical element is configured between the optical component and optotypes presentation unit of light, the light of sighting target light beam is changed by controlling optical element Learn the structure of characteristic.That is, can be the structure of mirage phantom lens dioptrometer (mirage phantom correction optical system) as correcting unit. In this case, for example, the sighting target light beam after being corrected from correction optical system is guide-lighting to tested eye via optical component.

For example, the subjective formula optometry equipment of present embodiment possesses objective type determination unit.For example, objective type determination unit Objectively determine the optical characteristics of tested eye.For example, the optical characteristics as the tested eye objectively determined, can enumerate eye Refractive power (for example, spherical degree, astigmatism degree, scattered optical axis angle etc.), polarization characteristic, lenticular thickness information etc..In addition, In the present embodiment, enumerate and illustrated to being detected exemplified by the objective type determination unit that is measured of eye ametropia force of eye.Separately Outside, for example, objective type determination unit possesses the eyeground injection measure light to tested eye and receives the measure optical system of its reflected light System (for example, objective type determines optical system 10).For example, the optical characteristics as the tested eye objectively determined, Ke Yishi The shooting result (shooting image) that is photographed by objective type determination unit and by carrying out dissection process to shooting result to obtain Parameter at least any one.That is, the optical characteristics as the tested eye objectively determined, if be based upon it is objective The characteristic of the shooting result of formula determination unit shooting.

For example, objective type determination unit can have the right side for being arranged to pair of right and left to be detected ophthalmically acceptable measure optical system and a left side It is detected ophthalmically acceptable measure optical system.In this case, for example, right tested ophthalmically acceptable measure optical system can be performed substantially simultaneously The measure of the left and right of system and left tested ophthalmically acceptable measure optical system.Moreover, in this case, for example, can determine in different When implement right tested ophthalmically acceptable measure optical system and left tested ophthalmically acceptable measure optical system left and right measure.It is for example, different Timing can be a measure optical system in right tested ophthalmically acceptable measure optical system and left tested ophthalmically acceptable measure optical system Measure complete timing.Moreover, for example, different timings can implement right tested ophthalmically acceptable measure optical system and a left side is detected During the measure of a measure optical system in ophthalmically acceptable measure optical system.

In addition, for example, objective type determination unit can carry out the measure of the tested eye in left and right by a measure optical system. In this case it is possible, for example, to be configured to, the measure that measure light carries out tested eye is projected on the eyeground of Xiang Yifang tested eye, and And in the measure completion of the eye of a side, adjusted in a manner of it can project measure light to the eyeground of the tested eye of the opposing party It is whole, to carry out the measure of the tested eye of the opposing party.

For example, measure optical system has the projection optics system for projecting measure light to the eyeground of examined human eye from light source System and using capturing element to the shooting optical system that is shot by determining light in the reflection on eyeground and the reflected light that obtains System.For example, measure optical system can be the optical system of the eye ametropia force of the tested eye of measure.In this case, for example, making To determine optical system, following structure can be enumerated：Via tested eye eyeground subpoint from portion of pupil center to tested eye The measure mark of shape, annularly extracts the fundus reflex light from fundus reflex, clap capturing element via pupil periphery Take the photograph the fundus reflex picture of ring-type.Moreover, in this case, for example, as measure optical system, following knot can be enumerated Structure：The measure mark of ring-type is projected from pupil periphery to eyeground, fundus reflex light is extracted from portion of pupil center, to make shooting first Part shoots the fundus reflex picture of ring-type.Moreover, in this case, for example, measure optical system can possess summer visitor-Hart The structure of graceful sensor.Moreover, in this case, for example, measure optical system can be had to tested eye projection slit Phase difference mode structure.

In the present embodiment, for example, control unit is subjectively determining the light of tested eye by subjective formula determination unit During learning characteristic, the optical characteristics of tested eye is objectively determined by objective type determination unit.In addition, for example, passing through visitor When sight formula determination unit objectively determines the optical characteristics of tested eye, subjective formula determination unit can be made special to the optics for being detected eye Property subjective measure continue.Moreover, for example, the optical characteristics of tested eye is objectively being determined by objective type determination unit When, subjective formula determination unit can be made to temporarily cease the subjective measure for being detected the optical characteristics of eye.In such a case, it is possible to Subjective formula determination unit is started again at when completing objective determination by objective type determination unit to being detected the optical characteristics of eye Subjectivity measure.

For example, in the present embodiment, possess special in the optics that tested eye is subjectively determined by subjective formula determination unit The structure of the optical characteristics of tested eye is objectively determined during property by objective type determination unit, thereby, it is possible to according to objective Measurement result and the change for catching the optical characteristics of the tested eye during subjective measure.Thus, scrutineer can account for The subjective measure of the changes in optical properties of tested eye during subjectivity measure.Therefore, scrutineer is subjectively determining tested eye During optical characteristics, the optical characteristics of tested eye can be accurately determined.

For example, as during the optical characteristics of tested eye is subjectively determined by subjective formula determination unit by objective Formula determination unit objectively determines the situation of the optical characteristics of tested eye, and control unit can carry out the master of at least more than one See the optical characteristics that tested eye during checking, is objectively determined by objective type determination unit.

For example, the subjective determination of at least more than one includes implementing the situation of a subjective determination, implements multiple subjective inspections Situation about looking into.In addition, for example, a subjective determination can be the inspection at least one optical characteristics for subjectively determining tested eye Look into.

For example, when implementing a subjective determination, control unit can implement a master by subjective formula determination unit See the optical characteristics that tested eye during checking, is objectively determined by objective type determination unit.

For example, when implementing multiple subjective determinations, control unit can implement multiple masters by subjective formula determination unit During seeing a subjective determination in checking, the optical characteristics of tested eye is objectively determined by objective type determination unit.And And for example, when implementing multiple subjective determinations, control unit can carry out the first subjective determination by subjective formula determination unit During inspection with the second subjective determination, the optical characteristics of tested eye is objectively determined by objective type determination unit.At this In the case of kind, for example, the first subjective determination and the second subjective determination can be the subjective inspections for determining identical optical characteristics Look into, the first subjective determination and the subjective determination that the second subjective determination can also be for determining different optical characteristics.

For example, subjective formula optometry equipment can possess：Transmitting element, send for starting based on objective type determination unit The objective determination of objective determination starts trigger signal；And receiving unit, receive objective determination and start trigger signal.For example, When starting trigger signal by transmitting element transmission objective determination and starting trigger signal by receiving unit reception objective determination, Control unit objectively determines tested eye during the subjective determination of at least more than one is carried out by objective type determination unit Optical characteristics.For example, the beginning of the objective determination based on objective type determination unit can manually be implemented, can also be automatic Implement.

For example, when manually implementing the structure of beginning of objective determination, setting, which starts switch conduct, will be used to start visitor Observe fixed objective determination and start the transmitting element that trigger signal is sent to subjective formula optometry equipment.For example, by by scrutineer Selection starts to switch and send objective determination and start trigger signal.For example, it may be objective determination is being received by receiving unit When starting trigger signal, control unit starts the measure based on objective type determination unit.For example, as at least one in progress The structure of the optical characteristics of tested eye is objectively determined during subjective determination above by objective type determination unit, is implemented extremely Few objective determination once.That is, for example, passing through objective type as during the subjective determination of at least more than one is carried out Determination unit objectively determines the structure of the optical characteristics of tested eye, it is possible to implement an objective determination is as minimum measure time Number, can also the measure number for implementing objective determination as maximum (real-time) all the time.

For example, it may be when wanting to implement an objective determination, the phase of the subjective determination of at least more than one is being carried out Between, once selected to implement objective determination by scrutineer starting switch.

In addition, for example, it may be, when wanting to implement multiple objective determination, carrying out the subjective inspection of at least more than one During looking into, repeatedly selected to implement multiple objective determination by scrutineer starting switch.Moreover, for example, also may be used To be, when wanting to implement multiple objective determination, during the subjective determination of at least more than one is carried out, pass through scrutineer couple Start switch once to be selected and implement multiple objective determination.

In addition, for example, when starting trigger signal by exporting an objective determination to implement multiple objective determination, entering During the row subjective determination of at least more than one, can once it be selected to implement in advance by scrutineer starting switch The objective determination of the number of setting.Moreover, for example, starting trigger signal by exporting an objective determination to implement multiple visitor Observation timing, during the subjective determination of at least more than one is carried out, it can be carried out once by scrutineer to starting switch Select and implement objective determination in timing set in advance.Moreover, for example, starting triggering letter by exporting an objective determination Number and when implementing multiple objective determination, can be split by scrutineer during the subjective determination of at least more than one is carried out Begin to switch and once selected and implement to determine all the time, so as to implement objective determination in real time.

For example, in the case where automatically carrying out the structure of beginning of objective determination, after subjective determination has been started, control Unit processed is controlled to transmitting element, and sending objective determination in timing set in advance starts trigger signal.For example, it may be When being received objective determination by receiving unit during trigger signal, control unit opens the measure based on objective type determination unit Begin.In addition, in the present embodiment, the control of transmitting element is implemented by control unit, but is not defined in this.For example, can be with Implemented by separately setting the control unit different from control unit.

Can be (for example, starting the projection of sighting target light beam when subjective measure starts for example, as timing set in advance State, start check program state, start subjective determination device operating portion operation state, start correct optical system State of the driving of system etc.), the time set in advance is when passing through (for example, since determining subjectivity by the scheduled time when Deng), switching check sighting target when, between subjective determination and subjective determination (in the case of carrying out multiple subjective determinations), checked people Carry out subjective determination in answer when (scrutineer carry out based on checked people answer operation when) etc. at least any one.When So, trigger signal can also be started in the timing output objective determination beyond above-mentioned record.

For example, objectively surveyed by objective type determination unit as during the subjective determination of at least more than one is carried out The structure of the optical characteristics of fixed tested eye, implements objective determination at least once.That is, for example, as in progress at least one The structure of the optical characteristics of tested eye is objectively determined during subjective determination more than individual by objective type determination unit, can be with Implement an objective determination as minimum measure number, can also the measure for implementing objective determination as maximum (real-time) all the time Number.

For example, want implement an objective determination when, can during the subjective determination of at least more than one is carried out, Start trigger signal in timing output objective determination set in advance, start the measure based on objective type determination unit.

In addition, for example, when wanting to implement multiple objective determination, the subjective determination of at least more than one can carried out Period, start trigger signal in timing output objective determination set in advance, to implement multiple objective determination.In such case Under, for example, triggering letter can be started by exporting multiple objective determination during the subjective determination of at least more than one is carried out Number implement multiple objective determination.In this case, for example, can carried out the phase of the subjective determination of at least more than one Between, start trigger signal by exporting an objective determination to implement multiple objective determination.

In addition, for example, starting trigger signal by exporting an objective determination to implement the situation of multiple objective determination Under, trigger signal can be started by the objective determination exported once during the subjective determination of at least more than one is carried out And implement the objective determination of number set in advance.Moreover, for example, start trigger signal in the objective determination by exporting once And when implementing multiple objective determination, can be once objective by exporting during the subjective determination of at least more than one is carried out Measure starts trigger signal and implements multiple objective determination in timing set in advance.Moreover, for example, objective by exporting once When observation starts trigger signal surely and implements multiple objective determination, it can implement to determine all the time, so as to implement objective survey in real time It is fixed.

For example, in the present embodiment, control unit objectively determines the optics of tested eye by objective type determination unit Characteristic and obtain the first optical characteristics, and in the phase for the optical characteristics that tested eye is subjectively determined by subjective formula determination unit Between the optical characteristics of tested eye objectively determined to obtain the second optical characteristics by objective type determination unit.

For example, in the present embodiment, subjective formula optometry equipment can possess acquisition unit.For example, in the present embodiment, Subjective formula optometry equipment can possess output unit.For example, acquisition unit is obtained based on the first optical characteristics and the second optics spy The regulation information of property.For example, output unit output regulation information.For example, in the present embodiment, objectively it is measured and takes The first optical characteristics is obtained, and the second optics objectively determined is obtained during the optical characteristics of tested eye is subjectively determined Characteristic.The regulation information based on acquired the first optical characteristics and the second optical characteristics is obtained, and exports regulation information.Pass through Such structure, according to the first optical characteristics and the regulation information of the second optical characteristics based on tested eye, can easily it take The change of the optical characteristics of tested eye between winner's observation periodically.Therefore, scrutineer, can be in subjectivity by using regulation information The optical characteristics of tested eye is easily and highly accurately determined during the optical characteristics of the tested eye of ground measure.

In addition, for example, bent by using the eye of the influence caused by the change for the adjustment state for being more prone to tested eye Luminous power is as the first optical characteristics and the second optical characteristics obtained when adjusting information, so as to be easier to catch the change of optical characteristics Change.And then in the case of using eye ametropia force, if at least using spherical degree, it is easier to catch the change of optical characteristics Change.Certainly, can utilize spherical degree, astigmatism degree and dissipate in the case of utilizing eye ametropia force when obtaining and adjusting information At least structure of any one in optical axis angle.

For example, as the timing for obtaining the first optical characteristics, quilt can subjectively determined by subjective formula determination unit Obtained before examining the optical characteristics of eye.In this case, for example, control unit can be subjective by subjective formula determination unit Before the optical characteristics of the tested eye of ground measure, the optical characteristics of tested eye is objectively determined by objective type determination unit, is obtained First optical characteristics.For example, in the present embodiment, it is special in the optics that tested eye is subjectively determined by subjective formula determination unit Before property, the optical characteristics of tested eye is objectively determined by objective type determination unit.Thus, based on subjective formula determination unit Subjective formula measure before, carry out the measure of objective type, thus can to inhibit due to using subjective formula determination unit and The state of the change of caused optical characteristics obtains the optical characteristics of the measure based on objective type.Inhibited therefore, it is possible to obtain The optical characteristics of the measure based on objective type of the change of optical characteristics, better regulation information can be obtained.

For example, as the timing for obtaining the first optical characteristics, can subjectively be determined by subjective formula determination unit Obtained after the optical characteristics of tested eye.In this case, for example, control unit can be complete by subjective formula determination unit Into after the subjective measure of the optical characteristics of tested eye, the optics that tested eye is objectively determined by objective type determination unit is special Property, obtain the first optical characteristics.For example, in the present embodiment, it is tested subjectively being determined by subjective formula determination unit After the optical characteristics of eye, the optical characteristics of tested eye is objectively determined by objective type determination unit.Thus, base is being carried out The measure of objective type is carried out after the measure of the subjective formula of subjective formula determination unit, therefore can be led with inhibiting due to using The optical characteristics of sight formula determination unit and measure of the state acquirement based on objective type of the change of caused optical characteristics.Therefore, The optical characteristics of the measure based on objective type for the change for inhibiting optical characteristics can be obtained, better regulation can be obtained Information.

It in addition, when obtaining the first optical characteristics, can regard tested eye E mists.For example, when obtaining the first optical characteristics Objective eye ametropia force measure in, can carry out first eye ametropia force preparation measure, based on preparation measure result, make by Inspection eye E mists regard.Can be the measure of the objective eye ametropia force determined by objective type determination unit for example, being determined as preparation, Can also be the measure of the subjective eye ametropia force determined by subjective formula determination unit.

For example, in mist apparent time, can be moved by display 31 along the direction of optical axis L 2 regard tested eye E mists.This In the case of, for example, the position that display 31 is temporarily shifted to focus relative to tested eye E can be made.Moreover, for example, regarded in mist When, optical component (for example, lens etc.) can also be made to be plugged relative to light path.Moreover, for example, in mist apparent time, can also switch It is configured at the optical component (for example, lens etc.) of light path.For example, after mist regards, can for mist depending on tested eye use In the formal measure for the eye ametropia force for obtaining the first optical characteristics.So, regarded by mist, the regulation work(of tested eye can be suppressed Can, the first optical characteristics inhibited in the state of adjustment function can be obtained.

In addition, for example, as the timing for obtaining the first optical characteristics, can subjectively be surveyed by subjective formula determination unit Obtained during the optical characteristics of fixed tested eye.In this case, for example, can by subjective formula determination unit subjectively The first optical characteristics is obtained during the optical characteristics of the tested eye of measure, and second is obtained after the first optical characteristics is achieved Optical characteristics.

For example, as long as the information that the first optical characteristics and the second optical characteristics can be compared by regulation information is i.e. Can.Can be by carrying out difference processing with the second optical characteristics to obtain to the first optical characteristics for example, as regulation information Information.For example, can be the first optical characteristics and the second optical characteristics by the regulation information for carrying out difference processing to obtain The difference result of parameter and the error image etc. of shooting image at least any one.In addition, for example, as above-mentioned ginseng Number, can be at least any one numerical value in surface of sphere numerical value, astigmatism numerical value, astigmatism shaft angle angle value etc..

Can carry out difference to the brightness value of each pixel shooting image to handle for example, as error image Image.In this case, for example, when the first optical characteristics and the second optical characteristics do not change, the pixel in error image Brightness value be 0 (due to for same shooting image, therefore 0) its difference is.Moreover, in this case, for example, in the first light When learning characteristic and the second optical characteristics in the presence of change, in error image, because the brightness value of each shooting image is not 0, therefore Occurs picture on image.

In addition, for example, when carrying out difference processing, the optical characteristics (benchmark as the benchmark for carrying out difference processing Data), arbitrary optical characteristics can be set.For example, as difference result, Ke Yishi, for reference data, by by each light Learn characteristic and carry out difference processing to obtain.

For example, when only achieving the first optical characteristics and the second optical characteristics, can be by the first optical characteristics and second At least one party in optical characteristics is as reference data.For example, gone back in addition to the first optical characteristics and the second optical characteristics When obtaining optical characteristics, as long as arbitrary optical characteristics is set as into reference data among the optical characteristics of acquirement.Separately Outside, for example, when optical characteristics is set as into reference data, benchmark can be selected among multiple optical characteristics by scrutineer Data.Moreover, for example, when optical characteristics is set as into reference data, base value can be automatically set by acquisition unit According to.In this case, for example, acquisition unit can by optical characteristics minimum, (solstics side be (not among multiple optical characteristics Add eye regulation side)) optical characteristics be set as reference data.Moreover, for example, acquisition unit can be from multiple optics Among characteristic, the optical characteristics just obtained before the new reference data for obtaining optical characteristics is set as reference data.Moreover, example Such as, acquisition unit, can be among multiple subjective determinations from the light obtained by objective determination when implementing multiple subjective determinations Learn in characteristic and arbitrary optical characteristics is set as reference data.

In addition, as difference result, can be shown by numerical value, coordinate diagram etc..For example, objective determination is being carried out in real time Or during multiple objective determination, these difference results can continuously be shown., then can be true if formed as such structure Recognize the upset condition of optical characteristics.

In addition, for example, can based in difference result and error image at least any one judge the change of optical characteristics Whether good change.In this case, for example, identifying unit can be set, identifying unit judges difference result and shooting image Change in shape result etc. at least any one result whether meet benchmark set in advance, and export result of determination.For example, Whether as result of determination, it is overcorrection that can export.

For example, in the present embodiment, regulation information is obtained by comparing processing, thus, according to by comparing processing Regulation information, can more easily obtain the change of the optical characteristics of tested eye during subjective measure.Therefore, scrutineer exists When subjectively determining the optical characteristics of tested eye by using regulation information, it can be easier and accurately determine tested eye Optical characteristics.

Can be the first optical characteristics and the second optical characteristics for example, as regulation information.In this case, for example, Can be that the first optical characteristics and the second optical characteristics arrange the information formed (for example, matching somebody with somebody in first area as regulation information The first optical characteristics is equipped with, the information of the second optical characteristics is configured with the second area different from first area).Moreover, In this case, can be the information that the first optical characteristics and the second optical characteristics can be switched to display as regulation information. Moreover, can be the letter that the first optical characteristics is superimposed with the second optical characteristics for example, as regulation information in this case Breath.In addition, the information of superposition can be the information that the first optical characteristics is superimposed with least a portion in the second optical characteristics.Separately Outside, for example, as regulation information, it is configured to and is implemented with above- mentioned information.

For example, in the present embodiment, subjective formula optometry equipment can possess output unit.For example, output unit exports Adjust information.For example, output unit can be in the structure of display by regulation presentation of information.Moreover, for example, output unit can Be printing regulation information structure.For example, output unit can will adjust information to other devices (other control units) The structure of transmission.In this case, for example, it may be, other devices receive regulation information and based on the regulation letters received Breath carries out various controls.

Can be that control unit, acquisition unit (acquirement control unit), output unit are (defeated in addition, in the present embodiment Go out control unit) by the structure of dual-purpose.Moreover, for example, it may be control unit, acquisition unit, output unit are dividually independent The structure of setting.Certainly, above-mentioned each control unit can be made up of multiple control units.

In addition, in the present embodiment, enumerate special in the optics that tested eye is subjectively determined by subjective formula determination unit Carried out exemplified by the subjective formula optometry equipment for the optical characteristics that tested eye is objectively determined by objective type determination unit during property Illustrate, but be not defined in this.It can also be the structure that subjective formula optometry equipment can obtain regulation information.In such case Under, for example, control unit can objectively determine the optical characteristics of tested eye to obtain the first light by objective type determination unit Characteristic is learned, and quilt is objectively determined by objective type determination unit in the different timing of the timing from obtaining the first optical characteristics Examine the optical characteristics of eye and obtain the second optical characteristics.For example, acquisition unit can be obtained based on the first optical characteristics and second The regulation information of optical characteristics.For example, output unit can export regulation information.For example, in the present embodiment, objectively survey The optical characteristics of fixed tested eye and obtain the first optical characteristics, and determine the timing from obtaining the first optical characteristics is different When, the optical characteristics of tested eye is objectively determined by objective type determination unit to obtain the second optical characteristics.Obtain based on institute The first optical characteristics and the regulation information of the second optical characteristics obtained, and export regulation information.By such structure, check People can obtain the variable condition of the optical characteristics of tested eye when using subjective formula optometry equipment.Thus, subjective formula is being used When optometry equipment carries out the measure of tested eye, tested eye can be accurately determined.

For example, in the present embodiment, subjective formula optometry equipment can possess setup unit (for example, control unit 70).Example Such as, in the present embodiment, subjective formula optometry equipment can possess the first correction unit (for example, control unit 70, correction optical system System is 60).For example, setup unit can be used for subjectively being determined by subjective formula determination unit based on regulation information to set The correcting value that the adjustment state change of caused tested eye is corrected during the optical characteristics of tested eye.In addition, as school Positive quantity, it is preferably set to that the adjustment state of caused tested eye can be changed to the correcting value offset, as long as but will not The degree of obstacle is caused to subjective determination, is not defined in this.For example, the first correction unit can be based on being set by setup unit Fixed correcting value, enter the correction for being about to offset in the adjustment state change that eye is detected caused by subjective formula determination unit.For example, In present embodiment, the correcting value for being corrected to the adjustment state change for being detected eye is set based on regulation information, and The correction for being about to offset in the adjustment state change that eye is detected caused by subjective formula determination unit is entered based on correcting value.Thus, During the optical characteristics of tested eye is subjectively determined by subjective formula determination unit, even in the optical characteristics hair of tested eye In the case of having given birth to change, it can be also measured in the state of the change of optical characteristics is offset.Thus, surveyed subjectively During the optical characteristics of fixed tested eye, the optical characteristics of tested eye can be easily and highly accurately determined.

For example, correcting value can be made for regulation information each parameter and form set in advance, made table Lattice are stored in memory (for example, memory 72).In this case, for example, setup unit can be recalled and adjusted from memory Correcting value corresponding to nodular state and set.Moreover, for example, for correcting value, the every of information can will be adjusted for exporting The arithmetic expression of the correcting value of individual parameter is stored in memory, and obtains correcting value using arithmetic expression.

Can correct the structure that optical system is also used as the first correction unit for example, as the first correction unit.Example Such as, in the present embodiment, it is also used as the first correction unit by correcting optical system, it is not necessary to which complicated control is separately set Put for adjustment state to be changed into the correction unit offset, therefore optical aberration can be corrected with easy structure.Example Such as, as the first correction unit, special correction unit can be separately set.In this case, for example, as the first correction Unit, can use in spherical lens, cylindrical lens, crossing cylinder lens, rotating prism, corrugated modulation element etc. at least The structure of any one.Certainly, for example, as the first correction unit, the component different from the component of above-mentioned record can also be used.

In addition, can be control unit, setup unit (setting control unit), the first correction list in the present embodiment The control unit of member is by the structure of dual-purpose.Moreover, for example, it is also possible to it is the control of control unit, setup unit, the first correction unit The structure that unit processed is dividually separately provided.Certainly, above-mentioned each control unit can be made up of multiple control units.

In addition, in the present embodiment, for example, as subjective formula optometry equipment, it is configured to that optical system will be corrected Configure in the light path of measure optical system.Certainly, as subjective formula optometry equipment, can also be configured to correct optical system not Configure in the light path of measure optical system.

For example, in the case of in light path of the correction optical system configurations in measure optical system, subjective formula optometry equipment Can possess the second correction unit (for example, control unit 70).For example, the second correction unit can rectifying based on correction optical system Positive information, measurement result obtained from objectively determining tested eye as objective type determination unit is corrected.For example, second Correct unit can based on correction optical system correction information, by will correct optical system correction state counteracting in a manner of, Measurement result obtained from objectively determining tested eye as objective type determination unit is corrected.For example, in this embodiment party In formula, when correction optical system in the light path of objective type determination unit be present, the measure due to objectively determining can be corrected Light beam deviation of caused optical characteristics through overcorrection optical system.Thus, when being corrected by correcting optical system Even if in the case of having carried out objective determination, it also can accurately obtain optical characteristics.For example, especially obtaining based on logical During the regulation information at least two optical characteristics crossed objective determination and obtained, it is difficult to due to producing deviation between optical characteristics It is compared, therefore this technology is more efficient.

For example, the second correction unit can be corrected to optical characteristics and be used as measurement result.In addition, obtaining first When optical characteristics and the second optical characteristics are as optical characteristics, at least one party in the first optical characteristics and the second optical characteristics It is corrected.Moreover, for example, the second correction unit can be corrected to regulation information is used as measurement result.

In addition, can be control unit and second correction unit (the second Corrective control unit) quilt in the present embodiment The structure of dual-purpose.Moreover, for example, it may be structure that control unit is dividually separately provided with the second correction unit.Certainly, on Stating each control unit can be made up of multiple control units.

In addition, in the present embodiment, for special in the optics that tested eye is subjectively determined by subjective formula determination unit The structure of the optical characteristics of tested eye is objectively determined during property by objective type determination unit, can be used for subjectively determining The subjective determination (preceding ophthalmoscopy) of optical characteristics during the state of tested eye wearing spectacles.In this case, for example, in quilt In the state of examining eye wearing spectacles, can objectively it be determined by objective type determination unit to obtain the first optical characteristics, and During the optical characteristics of tested eye is subjectively determined, the second optics objectively determined by objective type determination unit is obtained Characteristic.Moreover, for example, the regulation information based on acquired the first optical characteristics and the second optical characteristics can be obtained, and it is defeated Go out to adjust information.

For example, in obtaining difference result and error image when at least any one is as regulation information, for example, can be with Based in difference result and error image at least any one judge whether the change of optical characteristics good.In such case Under, whether for example, as result of determination, it is overcorrection that can export.For example, whether being overcorrection by output, it is able to confirm that Whether the glasses currently worn are overcorrection.

For example, as one, in the state of tested eye wearing spectacles, the long sight that infinity can be presented is taken with sighting target Optical characteristics, and present and be in a ratio of the sighting targets of the positive number of degrees with sighting target to obtain optical characteristics with the long sight of infinity.This In the case of, adjustment state can be obtained based on each optical characteristics calculated.Thereby, it is possible to the glasses for confirming currently to wear whether For overcorrection.

In the present embodiment, for example, subjective formula optometry equipment can possess initial value setup unit (for example, control unit 70).In this case, for example, control unit can start the optical characteristics of tested eye by subjective formula determination unit Subjective measure after, the optical characteristics of tested eye is objectively determined by objective type determination unit to obtain the optics of tested eye Characteristic.For example, the optical characteristics of the tested eye objectively determined by control unit can be set as by initial value setup unit The initial value of correction optical system when subjectively determining the optical characteristics of tested eye by subjective formula determination unit.In addition, example Such as, as the optical characteristics for being set as initial value, spherical degree, the cylinder number of degrees, cylinder axis, polarization characteristic and aberration can be enumerated Amount etc. at least any one.It is of course also possible to optical characteristics other than the above is set as initial value.For example, in this implementation In mode, after the subjective measure for the optical characteristics for having started tested eye by subjective formula determination unit, determined by objective type Unit objectively determines the optical characteristics of tested eye and obtains the optical characteristics of tested eye.The light of the tested eye objectively determined Learn correction optical system when characteristic is set to subjectively determine the optical characteristics of tested eye by subjective formula determination unit Initial value.Pass through such structure, it is not necessary to the standby subjectivity for implementing subjective determination device again untill objective determination is completed Measure, it can promptly determine the optical characteristics of tested eye.

As long as for example, state that the control of the subjective measure of the beginning of subjective measure starts.More specifically, example Such as, the beginning of subjective measure can be the state for the projection for starting sighting target light beam, start to check the state of program, start subjective inspection Look into the state of the operation of the operating portion of device, start to correct state of driving etc. of optical system at least any one.

For example, the subjective determination on being set as initial value, initial value setup unit can be real when starting objective determination The optical characteristics of the tested eye objectively determined is set as initial value in the subjective determination applied.In this case, for example, The optical characteristics of the tested eye objectively determined by objective type determination unit is set as by initial value setup unit, is starting The master of the optical characteristics for the tested eye implemented before objective determination based on objective type determination unit by subjective formula determination unit The initial value of correction optical system during observation is fixed.For example, in the present embodiment, will be by objective type determination unit objectively The optical characteristics of the tested eye determined is set as, passes through subjectivity before the objective determination based on objective type determination unit starts The initial value of correction optical system in the subjective measure of the optical characteristics for the tested eye that formula determination unit is implemented.By such Structure, it can promptly carry out the subjective measure based on subjective determination device.

In addition, for example, subjective determination on being set as initial value, initial value setup unit can be with starting objective survey Regularly in the different subjective determination (the second subjective determination) of the subjective determination (the first subjective determination) of implementation, will objectively it determine The optical characteristics of tested eye be set as initial value.In this case, for example, control unit can determine by subjective formula Unit performs the first subjective measure of the optical characteristics for subjectively determining tested eye and then secondary by subjective formula determination unit Perform the second subjective measure of the optical characteristics for subjectively determining tested eye.For example, control unit can start the first master After observation is fixed, the optical characteristics of tested eye is objectively determined by objective type determination unit.For example, initial value setup unit can So that the optical characteristics of the tested eye objectively determined by objective type determination unit is set as into the described second subjective survey Fixed initial value.For example, in the present embodiment, the light for being detected eye is subjectively determined being performed by subjective formula determination unit Learn the first subjective measure of characteristic and then the secondary optical characteristics that the tested eye of subjectively measure is performed by subjective formula determination unit The second subjective measure.After the first subjective measure has been started, tested eye is objectively determined by objective type determination unit Optical characteristics, and the optical characteristics of the tested eye objectively determined is set as the second subjective initial value determined.Pass through this The structure of sample, when subjective measure is carried out again, due to having been achieved with initial value, therefore energy in different subjective measure It is enough to be promptly measured.

For example, the first subjective determination can be that measure and the optical characteristics identical optics by the second subjective determination measure are special The subjective determination of property.Moreover, for example, the first subjective determination can be determined with the optical characteristics by the second subjective determination measure not The subjective determination of same optical characteristics.In this case, can subjectively determine quilt for example, as the first subjective determination The subjective determination (bore hole inspection) of optical characteristics during the bore hole of inspection eye.Moreover, for example, as the first subjective determination, Ke Yishi The subjectively subjective determination (preceding ophthalmoscopy) of the optical characteristics during state of the tested eye wearing spectacles of measure.In these situations Under, for example, the first subjective measure can the optical characteristics of sighting target light beam is changed by correcting optical system Subjective measure without the optical characteristics that tested eye is subjectively determined under correction state, the second subjective measure can be by correcting light System makes the optical characteristics of sighting target light beam change and subjectively determines the subjective measure of the optical characteristics of tested eye.

In addition, in the present embodiment, the sighting target light beam of projection optics system can be used as by subjective formula optometry equipment Fixation mark when objectively determining the optical characteristics of tested eye by objective type determination unit for making to be detected eye fixation.For example, In the present embodiment, the sighting target light beam of the projection optics system in subjective detection unit is set to determining list by objective type Fixation mark when member objectively determines the optical characteristics of tested eye for making to be detected eye fixation.By such structure, can subtract Few component, can carry out constituent apparatus with easy structure.Moreover, unnecessary space can be reduced, it is capable of the small-sized of realization device Change.

In addition, can be that (initial value setting control is single with initial value setup unit for control unit in the present embodiment Member) by the structure of dual-purpose.Moreover, for example, it may be structure that control unit is dividually separately provided with initial value setup unit.

For example, deflecting mirror 81R, the deflecting mirror of left eye of the right eye that deflecting mirror 81 is set with having pair of right and left respectively 81L.For example, deflecting mirror 81 is configured between correction optical system 60 and tested eye.That is, correcting optical system 60 has left and right one The right eye set over the ground correction optical system and left eye correction optical system, the deflecting mirror 81R of right eye are configured in right eye With between correction optical system and right eye ER, the deflecting mirror 81L configurations of left eye are in left eye correction optical system and left eye ER Between.For example, deflecting mirror 81 is preferably configured in pupil conjugate position.

For example, the deflecting mirror 81R of right eye is from right eye with the determination unit 7R light beams projected to reflecting, to right eye ER It is guide-lighting.Moreover, for example, reflecting the reflected light reflected by right eye ER, ophthalmically acceptable determination unit 7R is guide-lighting to the right.It is for example, left Ophthalmically acceptable deflecting mirror 81L is guide-lighting to left eye EL to being reflected from left eye with the determination unit 7L light beams projected.Moreover, for example, The reflected light reflected by left eye EL is reflected, ophthalmically acceptable determination unit 7L is guide-lighting to the left.In addition, in the present embodiment, lift Go out and reflected using deflecting mirror 81 as the light beam to being projected from determination unit 7 and to deflecting member guide-lighting tested eye E Illustrated exemplified by structure, but be not defined in this.As long as being reflected the light beam projected from determination unit 7 and to tested Deflecting member guide-lighting eye E.For example, as deflecting member, prism, lens etc. can be enumerated.

For example, driver element 83 is made up of motor (drive division) etc..It is used to drive right eye for example, driver element 83 has Deflecting mirror 81R driver element 83R, deflecting mirror 81L for driving left eye driver element 83L.For example, it can lead to The driving of over-drive unit 83 and deflecting mirror 81 is moved in X direction.For example, the deflecting mirror 81R of right eye and a left side can be passed through The distance between the deflecting mirror 81R of right eye and left eye deflecting mirror 81L, energy are changed in ophthalmically acceptable deflecting mirror 81L movement The interocular distance of enough and tested eye matchingly changes the distance in the X-direction between right eye light path and left eye light path.

For example, driver element 82 is made up of motor (drive division) etc..It is used to drive right eye for example, driver element 82 has Deflecting mirror 81R driver element 82R, deflecting mirror 81L for driving left eye driver element 82L.For example, pass through drive The driving of moving cell 82 and to carry out deflecting mirror 81 in rotary moving.For example, driver element 82 makes deflecting mirror 81 relative to level side The rotary shaft of rotary shaft and vertical direction (Y-direction) to (X-direction) and rotate.That is, driver element 82 makes deflecting mirror 81 along XY Direction rotates.In addition, the rotation of deflecting mirror 81 can be horizontally oriented or vertical direction in a side.Furthermore it is possible to it is on the right side Ophthalmically acceptable light path and left eye are respectively arranged with the structure of multiple deflecting mirrors with light path.For example, it can enumerate on right eye light path and a left side Ophthalmically acceptable light path sets the structure of two deflecting mirrors (for example, in right eye light path two deflecting mirror etc.) respectively.In this case, Can be that the deflecting mirror of a side rotates in X direction, the deflecting mirror of the opposing party rotates along Y-direction.For example, the rotation by deflecting mirror 81 Transfer is dynamic so that deflected for the picture for correcting optical system 60 to be formed in the light beam for being detected the apparent at the moment of eye, thus, it is possible to Enough forming position for optically correcting picture.

For example, concave mirror 85 is shared in right eye with determination unit 7R and left eye determination unit 7L.For example, concave mirror 85 In comprising left eye light path of the right eye with the right eye light path of correction optical system and comprising left eye correction optical system altogether With.That is, concave mirror 85 is configured at the right eye light path comprising right eye correction optical system and corrects optical system comprising left eye The position that the left eye of system is passed through with light path.Certainly, concave mirror 85 may not be shared structure.Can be comprising the right side The right eye of ophthalmically acceptable correction optical system is recessed with being set respectively in light path with the left eye of correction optical system with light path and comprising left eye The structure of face mirror.For example, concave mirror 85 is guide-lighting to tested eye by the sighting target light beam for having passed through correction optical system, it will pass through and rectify The picture of the sighting target light beam of positive optical system is formed in tested eye at the moment.In addition, in the present embodiment, enumerate using concave mirror Exemplified by 85 structure, but this is not defined in.Various optical components can be used.For example, as optical component, can use saturating Mirror, level crossing etc..

For example, the dual-purpose in subjective formula determination unit and objective type determination unit of concave mirror 85.For example, determined from subjective formula The sighting target light beam that optical system 25 projects projects via concave mirror 85 to tested eye.Moreover, for example, determine optical system from objective type The measure light of the projection of system 10 projects via concave mirror 85 to tested eye.Moreover, for example, projected from objective type measure optical system 10 Measure light reflected light determined via concave mirror 85 to objective type optical system 10 light receiving optical system 10b it is guide-lighting.In addition, In the present embodiment, the reflected light for enumerating the measure light of objective type measure optical system 10 is surveyed via concave mirror 85 to objective type Exemplified by the structure of light receiving optical system 10b leaded lights for determining optical system 10, but this is not defined in.Can be objective type measure light Structure of the reflected light of the measure light of system 10 not via concave mirror 85.

More specifically, for example, in the present embodiment, at least subjective formula determination unit from concave mirror 85 to tested Eye E between optical axis and objective type determination unit in from concave mirror 85 to the optical axis between tested eye E by coaxially forming.Separately Outside, in the present embodiment, by dichronic mirror 35, subjective formula is determined into the optical axis L 2 of optical system 25 and objective type determines optics The optical axis L 1 of system 10 synthesizes, so as to as coaxial.

Hereinafter, the light path of subjective formula determination unit is illustrated.For example, subjective formula determination unit will be passed through using concave mirror 85 The sighting target light beam of correction optical system 60 reflects to tested eye direction, thus that sighting target light beam is guide-lighting to tested eye, and will pass through The sighting target light beam of correction optical system 60 as optical is formed in tested eye at the moment with predetermined inspection distance.That is, Sighting target light beam is reflected as almost parallel light beam by concave mirror 85.Therefore, the sighting target picture from checked people seem than from Tested actual distances of the eye E untill display 31 is remote.That is, by using concave mirror 85, can with predetermined inspection away from From position see sighting target light beam picture mode to checked people present sighting target picture.

Illustrate in more detail.In addition, in the following description, left eye is enumerated with being illustrated exemplified by light path.On the right side In ophthalmically acceptable light path, also turn into the structure same with left eye light path.For example, in the subjective formula determination unit of left eye, from a left side The sighting target light beam that ophthalmically acceptable determination unit 7L display 13 projects incides astigmatism correction optical system 63 via light projector lens 33. Pass through the sighting target light beam of astigmatism correction optical system 63 via speculum 36, dichronic mirror 35, dichronic mirror 29, object lens 14, it is incident To correction optical system 90.Passed through the sighting target light beam of correction optical system 90 from left eye with determination unit 7L towards left eye Deflecting mirror 81L is projected.The sighting target light beam for being projected with determination unit 7L from left eye and being reflected by the deflecting mirror 81 of left eye is by semi-transparent Semi-reflective mirror 84 reflects towards concave mirror 85.By the sighting target light beam of concave mirror left eye EL is reached through semi-transparent semi-reflecting lens 84.

Thus, on the basis of left eye EL eyeglasses-wearing position (for example, being 12mm or so away from corneal vertex) and by rectifying Sighting target picture after positive optical system 60 is corrected is formed on left eye EL eyeground.Therefore, it is equivalent to astigmatism correction optical system 63 Correction optical system as configuring situation and spherical degree before eyes (in the present embodiment, drive mechanism 39 drives) The situation of the adjustment progress before eyes of spherical degree, checked people can be regarded via concave mirror 85 with natural state visual sight Target picture.In addition, be also the structure same with left eye light path in right eye light path in the present embodiment, it is tested with two The correction light for passing through pair of right and left on the basis of eye ER, EL eyeglasses-wearing position (for example, being 12mm or so away from corneal vertex) Sighting target picture after system 60 is corrected is formed on the eyeground of two tested eyes.So, checked people is straight with naturally visual state Depending on sighting target and the response to scrutineer is carried out, realizes the correction of correction optical system 60 until checking that sighting target is suitably observed Untill, the measure of the optical characteristics of tested eye is subjectively carried out based on the correction value.

Next, the light path of explanation objective type determination unit.In addition, in the following description, enumerate left eye is with light path Example illustrates.It is also the structure same with left eye light path in right eye light path.For example, the objective type in left eye determines In unit, the measure light of the injection of light source 11 of the projection optical system 10a in optical system 10 is determined from objective type by therefrom Correction optical system 90 is incided after lens 12 to object lens 14.The measure light for having passed through correction optical system 90 is surveyed from left eye The deflecting mirror 81L of order member 7L towards left eye is projected.From left eye with determination unit 7L injections and by the deflecting mirror 81 of left eye The measure light of reflection is reflected by semi-transparent semi-reflecting lens 84 towards concave mirror 85.Semi-transparent semi-reflecting lens are passed through by the measure light of concave mirror 84, left eye EL is reached, the spot light picture of point-like is formed on left eye EL eyeground.Now, by the prism 15 rotated around optical axis, Make the pupil projection image (projected light beam on pupil) of the hole portion of aperture mirror 13 eccentric rotary at high speed.

The light of the spot light picture formed on left eye EL eyeground is reflected, scattered and projects tested eye E, via measure light By light path and by the optically focused of object lens 14, via to dichronic mirror 29, dichronic mirror 35, prism 15, aperture mirror 13, relay lens 16, anti- Penetrate mirror 17.By the reflected light untill speculum 17 in the opening of light diaphragm 18 optically focused again, by collimation lens 19 Be shaped generally as collimated light beam (situation of emmetropia), annular beam be extracted as by ring lens 20, and as ring-type picture by The light of capturing element 22.By being parsed to the ring-type picture of light, the optical characteristics of tested eye can be objectively determined.

For example, control unit 70 possesses CPU (processor), RAM, ROM etc..For example, the CPU of control unit 70 is responsible for carrying out subjectivity The control of each component of formula optometry equipment 1.For example, the various information of RAM interim storages.Use is stored with the ROM of control unit 70 In various programs, the sighting target data for various inspections, initial value of the action for controlling subjective formula optometry equipment 1 etc..In addition, control Portion 70 processed can be made up of multiple control units (that is, multiple processors).

For example, nonvolatile memory (storage part) 72 and monitor are electrically connected with to control unit 70 (in present embodiment In, as operating portion) 4, various components etc..Nonvolatile memory (following, to be recited as memory) is even if 72 be power supply Supply is cut off the storage medium for the non-transitory that can also keep storage content.It is, for example, possible to use hard disk drive, flash memory ROM, OCT device 1 and USB storage of subjective formula optometry equipment 1 etc. is installed in a manner of removable is deposited as non-volatile Reservoir 72.For example, the control journey for controlling subjective formula determination unit and objective type determination unit is stored with memory 72 Sequence.

Hereinafter, the control action of subjective formula optometry equipment 1 is illustrated.Fig. 6 is the stream for illustrating the control action in the present embodiment The flow chart of journey.Scrutineer indicates that the lower jaw of checked people touches lower jaw platform 5 and observed and window 3 is presented.Scrutineer is in instruction quilt Scrutineer is kept a close watch on display 31 after the fixation mark shown, carries out the alignment for being detected eye.

When being switched when being selected alignment by scrutineer, control unit 70 starts to be directed at (S1) automatically.In addition, in the present embodiment In, illustrated in case of the optical characteristics for the tested eye for enumerating the measure long sight used time.In the same manner as the long sight used time, near The optical characteristics of tested eye can be also determined depending on the used time.

For example, control unit 70 detects the pupil of the tested eye in left and right from the face image photographed by photographing optical system 100 Hole site.For example, when detecting pupil position, control unit 70 controls master in a manner of preceding eye picture is shown in into monitor 4 Sight formula optometry equipment 1.For example, control unit 70 drives the deflecting mirror 81R of right eye, the deflecting mirror 81L of left eye and makes it respectively Rotated along XY directions.Moreover, for example, when detecting pupil position, control unit 70 can make right eye determination unit 7R and a left side Ophthalmically acceptable determination unit 7L is moved in X direction respectively.That is, control unit 70 carries out the alignment in XY directions by driving deflecting mirror 81, The alignment of Z-direction is carried out by driving determination unit 7.

In addition, in the present embodiment, enumerate by the driving of deflecting mirror 81 and determination unit 7 to adjust XYZ directions Illustrated exemplified by the structure of alignment, but be not defined in this.As long as can adjust tested eye and subjective formula determination unit and The structure of the position relationship of objective type determination unit.That is, as long as XYZ directions can be adjusted so that by correction optical system The structure that picture after 60 corrections is formed on the eyeground of tested eye.For example, it is also possible to be configured to, setting can make subjective formula Optometry equipment 1 moves subjective formula optometry equipment 1 relative to lower jaw platform 6 along the structure that XYZ directions are moved.Moreover, for example, make For the structure that deflecting mirror 81 and determination unit integratedly move along XYZ directions can be made, it can be set to carry out the adjustment in XYZ directions Structure.Moreover, for example, it is also possible to it is set to only carry out the structure of the adjustment in XYZ directions by deflecting mirror 81.In such case Under, for example, can enumerate, deflecting mirror 81 carries out rotation driving and deflecting mirror 81 is with change and the distance between determination unit Mode carries out the structure of Z-direction movement.In addition, for example, in alignment controls, two tested eyes can be shown on the monitor 4, The alignment control of two tested eyes is carried out on same picture.Moreover, for example, in alignment controls, can show on the monitor 4 The tested eye of one side, after the alignment control of the tested eye of a side is completed, the tested eye of the opposing party is included in monitor 4 On, carry out the alignment control of the tested eye of the opposing party.Moreover, for example, the alignment control of the tested eye based on a side can be set to As a result the structure of the alignment control of the tested eye of the opposing party is carried out.

For example, the picture of the detection correction optical system 60 of control unit 70 is offset relative to the position of tested eye.For example, control unit 70 are controlled based on the testing result detected to driver element so that for the picture by optical system 60 is corrected to tested eye The light beam deflection of guide-lighting apparent, the forming position of picture is corrected thus optically.So, the subjective formula optometry of present embodiment Device 1 possesses the tested eye of detection with correcting the position skew of optical system and the structure of optical the forming position for correcting picture. Thus, be corrected by offseting with correcting the position of optical system to being detected eye, can use device in position, energy It is enough to be accurately measured.

Control unit 70 is completed the output of signal based on alignment and sent for starting objective determination (objective determination) (S2) Objective determination start trigger signal (following, be recited as trigger signal).Believe when sending for the triggering for starting objective determination Number when, control unit 70 from objective type measure optical system 10 project measure light beam.In this case, light beam is respectively determined via inclined Tilting mirror 81R, 81L and after being reflected by concave mirror 85, are projected to the eyeground of tested eye.From the measure light of fundus reflex via recessed Face mirror 85 and by deflecting mirror 81R (81L) reflect after, measure image is photographed by capturing element 22.

For example, in the measure of objective eye ametropia force, the preparation measure of eye ametropia force can be carried out first, is surveyed based on preparation Fixed result makes display 31 be moved along the direction of optical axis L 2, thus regards tested eye E mists.That is, display 31 can be relative to quilt Examine eye E and be temporarily shifted to the position of focusing.It is then possible to the formal measure of eye ametropia force is carried out for the tested eye that mist regards. In formal measure, measure image is shot by capturing element 22, and the output signal from capturing element 22 (is surveyed as view data Determine image) and it is stored in memory 72.Then, control unit 70 carries out image analysis to the ring-type picture for being stored in memory 72 and asked Go out the value of the refractive power of each warp direction.Control unit 70 to the refractive power by implementing predetermined processing to obtain the long sight used time It is examined S (spherical degree), C (astigmatism degree), A (scattered optical axis angle) the objective eye ametropia force (objective value) of human eye.Gained To the objective value of long sight used time be stored in memory 72.

In the measure of above-mentioned objective eye ametropia force, control unit 70 can control correction optical system 90, in objective type Caused optical aberration in the light path of optical system 10 is determined to be corrected.In this case, from memory 72 obtain with by Correcting value corresponding to the refractive diopter that objective type measure optical system 10 determines, school is controlled based on acquired aberration correction quantity Positive optical system 90.

More specifically, correcting value is set according to the eye ametropia force obtained in preparation measure, the correction based on setting Amount corrects optical system 90 to drive.Thus, it is caused in the light path of objective type measure optical system 10 on formal measure Aberration is formally determined in the state of being corrected afterwards, therefore can accurately determine objective eye ametropia force.In addition, continuous When ground determines eye ametropia force (for example, carrying out multiple formal measure), correction optical system can be controlled based on each measurement result 90。

In addition, in the above description, determining the objective eye ametropia force of long sight, but this is not defined in, can also survey Determine the eye ametropia force i.e. objective eye ametropia force of myopia in the state of presenting sighting target with distance with myopia.In addition, objective eye Refractive power measure can be performed simultaneously with right and left eyes, can also right and left eyes with different timing implementations.

Next, carry out subjective measure (S3).Complete objective refraction power measure and performance monitor (in present embodiment In, as operating portion) 4 when, switch to the long sight of subjectivity with test near and distance pattern (subjective refractive power mode determination).

For example, control unit 70 can control display 31 and required for being shown in optical axis L 2 eyesight value sighting target (for example, The sighting target of eyesight value 0.8).After initial presentation sighting target is presented to tested eye, the long sight that scrutineer carries out checked people is used Test near and distance.When pressing the predetermined switch of monitor 4, the presented eyesight value sighting target of switching.

For example, scrutineer when the answer of checked people is correct option, switches to the sighting target of higher leveled eyesight value.Separately On the one hand, when the answer of checked people is wrong answer, the sighting target of the eyesight value of low one-level is switched to.That is, control unit 70 can Sighting target is switched with the signal changed based on the eyesight value from monitor 4.

In addition, scrutineer can change the correction number of degrees of correction optical system 60 using monitor 4, tested eye is obtained Long sight with subjective value (spherical degree S, astigmatism degree C, dissipate optical axis angle A).

In addition, correction optical system 60 the correction number of degrees be set as the different number of degrees by right and left eyes, can also right and left eyes set It is set to the identical number of degrees.In addition, subjective eye ametropia force measure can be performed with right and left eyes simultaneously, can also right and left eyes determined with different When implement.In addition, in different timings, sighting target can not be shown on the display 31 of non-measure eye, can also be by rectifying Positive optical system 60 makes its mist depending on (for example, adding certain refractive diopter for objective value).

After the subjective value of long sight has been obtained, the myopia test near and distance pattern of subjectivity can be switched to.Work as setting For myopia mode determination when, control unit 70 can be controlled to projection optics system 30, become and be based more on the receipts of deflecting mirror 81 Angle is held back, sighting target is presented with position in myopia.In addition, the presentation distance of the sighting target in myopia inspection can be based on coming from operating portion 4 operation signal and arbitrarily change.As a result, the presentation distance of sighting target is changed to myopia position from long sight with position.Separately Outside, myopia inspection in, can by myopia with position change sighting target presentation distance come subjectively obtain add the number of degrees, Adjusting force.

In this case, for example, control unit 70 can obtain the corresponding picture of presentation distance with sighting target from memory 72 Poor correcting value, correction optical system 90 is controlled based on acquired aberration correction quantity.Moreover, the presentation distance in sighting target is become When more, control unit 70 distance can be presented according to the sighting target of change to change the aberration correction quantity of correction optical system 90.Thus, In the case that distance is presented in the presence of change in sighting target, the sighting target for alleviating aberration can also be presented.In this case, control Portion 70 can change aberration correction quantity according to the correction number of degrees for the presentation distance for being attached with sighting target.

And then control unit 70 can be controlled to change according to the change of the position of appearing of sighting target to light deflecting member The convergent angle of the sighting target light beam of left and right.In this case, for example, control unit 70 can be obtained from memory 72 and convergency Aberration correction quantity corresponding to degree corresponding to the deflection angle of light deflecting member, and controlled based on acquired aberration correction quantity Correct optical system 90.Moreover, when the convergent angle of sighting target light beam is changed, control unit 70 can be according to the convergency of change Spend to change the aberration correction quantity of correction optical system 90.Thus, when convergent angle exists and changed, mitigation can also be presented The sighting target of aberration.

In the same manner as being checked with long sight, in myopia inspection, for example, scrutineer can use the predetermined of operating portion 4 Switch to change the correction number of degrees of correction optical system 60, to presenting the subjective eye ametropia force in the state of myopia sighting target (near-sighted with subjective value) is measured.In myopia inspection, control unit 70 can change school according to the change of the correction number of degrees The aberration correction quantity of positive optical system 90.

Here, in the present embodiment, subjective formula optometry equipment 1 possesses carries out objective determination during subjective measure is implemented To catch the structure of the change of the optical characteristics of tested eye.For example, in the present embodiment, based on during subjective measure is implemented The optical characteristics of the tested eye determined by objective type determination unit, to obtain regulation information.For example, regulation information can be used for Catch the change of the optical characteristics of the tested eye during implementing subjective measure.

Hereinafter, the acquirement (S5) for adjusting information is illustrated.For example, in the present embodiment, control unit 70 is surveyed by subjective formula During order member subjectively determines the optical characteristics (S3) of tested eye, tested eye is objectively determined by objective type determination unit Optical characteristics.

More specifically, for example, in the present embodiment, control unit 70 is objectively determined tested by objective type determination unit Eye optical characteristics and obtain the first optical characteristics.For example, control unit 70 is subjectively determining quilt by subjective formula determination unit During the optical characteristics for examining eye, the optical characteristics of tested eye is objectively determined by objective type determination unit to obtain the second light Learn characteristic.In addition, the optical characteristics determined by objective type determination unit can be stored in memory 72.

For example, in the present embodiment, it is tested subjectively being determined by subjective formula determination unit on the first optical characteristics Before the optical characteristics of eye, the optical characteristics of tested eye is objectively determined by objective type determination unit, to obtain the first optics Characteristic.For example, in the present embodiment, by the optical characteristics that the objective determination (S2) carried out before subjective determine obtains by with Make the first optical characteristics (for example, spherical degree, astigmatism degree, scattered optical axis angle).Certainly, as the first optical characteristics, also may be used To be separately by objective type determination unit before the optical characteristics of tested eye is subjectively determined by subjective formula determination unit The structure of acquirement.

For example, control unit 70 can after subjective measure has been started, when have passed through the time set in advance (for example, From being started subjective measure after 1 minute etc.), determine the second optical characteristics.In addition, it is not defined to be set as obtaining have passed through The structure of the second optical characteristics is obtained during the time of the timing of the second optical characteristics.Second optical characteristics can be configured to various Trigger to obtain.Can be (for example, starting sighting target when starting subjective measure for example, as the timing for obtaining the second optical characteristics The state of the projection of light beam, start check program state, start subjective determination device operating portion operation state, start Correct state of driving etc. of optical system), switching checks during sighting target, (carries out multiple masters between subjective determination and subjective determination See check situation) etc. at least any one.It is of course also possible to the timing output beyond above-mentioned record opens objective determination The trigger signal of beginning.

It is more alternatively, it is also possible to be obtained during the optical characteristics of tested eye is subjectively determined by subjective formula determination unit Individual optical characteristics.In this case, for example, control unit 70 can be set in advance after subjective measure has been started have passed through The second optical characteristics is obtained during the fixed time, then, optical characteristics is obtained whenever by the time set in advance (for example, the Three optical characteristics, the 4th optical characteristics etc.).

For example, control unit 70 obtains the regulation information based on the first optical characteristics and the second optical characteristics.For example, in this reality Apply in example, control unit 70 to the first optical characteristics and the second optical characteristics by carrying out difference processing to obtain regulation information.Separately Outside, in the following description, as the first optical characteristics and the second optical characteristics, the spherical degree using eye ametropia force is enumerated Illustrated exemplified by situation.In addition, in the present embodiment, as the first optical characteristics and the second optical characteristics, for refraction of eye Spherical degree in power is illustrated, but is not defined in this.For example, as the first optical characteristics and the second optical characteristics, Eye ametropia force is not defined to.Moreover, for example, as eye ametropia force, spherical degree, astigmatism degree and scattered optical axis angle can be used In it is at least any of.

More specifically, in the present embodiment, for example, control unit 70 subjectively determines according to by subjective formula determination unit The first eye ametropia force obtained before the optical characteristics of tested eye by subjective formula determination unit with subjectively determining tested eye The difference of the second eye ametropia force obtained during optical characteristics, to obtain regulation information.For example, in the ball of the first eye ametropia force The face number of degrees are the spherical degree of 1.0 diopters (D) and the second eye ametropia force when being 3.0D, and control unit 70 carries out difference processing, takes Spherical degree 2.0D is obtained as regulation information.

Now, for example, control unit 70 can be based on the correction information for correcting optical system, to passing through objective type determination unit Measurement result obtained from objectively determining tested eye is corrected.For example, it is that objective type measure is single in subjective formula optometry equipment In the case of structure of the measure light beam of member via the correction optical system of subjective formula determination unit, when obtaining the first optical characteristics Correction optical system 60 correction state (configuration status of optical component) with obtain the second optical characteristics when correction optics The correction state of system 60 is different sometimes.Therefore, when by the first optical characteristics compared with the second optical characteristics, not The correction state of correction optical system is considered in the case of being compared, and is used as regulation information, it is difficult to obtain high-precision knot Fruit.

In the following description, the correction information based on correction optical system is enumerated to correct the first optical characteristics and second Illustrated in case of optical characteristics.In addition, in the present embodiment, enumerate based on correction information to correct the first optics Illustrated exemplified by the structure of characteristic and the second optical characteristics, but be not defined in this.For example, it is also possible to based on correction information come Correction regulation information.

For example, in the present embodiment, control unit 70 corrects the first optics spy based on the correction information of correction optical system Property and the second optical characteristics.For example, control unit 70 obtains the correction information for correction.For example, control unit 70 is from memory 72 The correction information of correction optical system when obtaining the first optical characteristics is recalled (for example, spherical degree, the cylinder number of degrees, cylinder Axle).Moreover, for example, control unit 70 recalls the correction information of correction optical system when obtaining the second optical characteristics (for example, ball The face number of degrees, the cylinder number of degrees, cylinder axis).In addition, the correction information on correcting optical system, as long as control unit 70 will obtain respectively The correction information of correction optical system during optical characteristics is established with each optical characteristics and is associatedly stored in memory 72.

For example, control unit 70 recalls the first correction information and the acquirement second when obtaining the first optical characteristics from memory 72 The second correction information during optical characteristics.For example, control unit 70 can correct the first optical characteristics based on the first correction information, Second optical characteristics is corrected based on the second correction information.For example, the spherical degree in the first correction information is 1.0D, second rectifys The spherical degree of positive information is 4.0D, the spherical degree of the first optical characteristics is 1.0D and the spherical degree of the second optical characteristics is During 5.0D, the spherical degree of the first optical characteristics when not correcting the influence of optical system is 0D, does not correct optical system Influence when the spherical degree of the second optical characteristics be 1.0D.Accordingly, when the situation of the influence in no correction optical system Under when carrying out difference processing to the spherical degree of the spherical degree of the first optical characteristics and the second optical characteristics, believe as regulation Breath, is 1.0D.I.e., it is known that the change of 1.0D spherical degree is generated during subjective measure is implemented.In addition, in above-mentioned knot In structure, on correcting information, enumerate and be illustrated exemplified by spherical degree, but be not defined in this.For example, as correction letter Breath, it can use at least any of in spherical degree, astigmatism degree and scattered optical axis angle.

In addition, not carrying out correcting the driving (not correcting) of optical system when obtaining the first optical characteristics, and only taking In the case of the driving (correction) that correction optical system has been carried out when obtaining the second optical characteristics, pass through the second correction information Only the second optical characteristics is corrected, the regulation information of correction optical system is considered thus, it is possible to obtain.Certainly, when taking Do not carry out correcting the driving (not correcting) of optical system when obtaining the second optical characteristics, and only carried out when obtaining the first optical characteristics In the case of the driving (correction) of correction optical system, only the first optical characteristics is carried out by the first correction information Correction, the regulation information of correction optical system is considered thus, it is possible to obtain.

In addition, in the present embodiment, enumerate based on correction information to correct the first optical characteristics and the second optical characteristics In case of be illustrated, but be not defined in this.For example, it is also possible to regulation information is corrected based on correction information. In this case, for example, control unit 70 carries out difference processing to obtain for school to the first correction information and the second correction information Positive correction information.For example, the spherical degree in the first correction information is 1.0D, the spherical degree of the second correction information is When 4.0D, the spherical degree of the first optical characteristics are 1.0D, the spherical degree of the second optical characteristics is 5.0D, according to the first correction The difference of information and the second correction information, in order to which the correction information obtained for correction is 3.0D.Moreover, for example, according to The difference of one optical characteristics and the second optical characteristics, regulation information is 4.0D.Therefore, regulation is corrected by using correction information Information, it is contemplated that the regulation information for correcting the influence of optical system is 1.0D.

As described above, based on information is corrected, as being corrected to measurement result obtained from objectively determining tested eye, The measure light beam due to objective determination can be corrected via the deviation for correcting optical system and caused optical characteristics.Thus, In the case of having carried out objective determination when being corrected by correcting optical system, optics also can be accurately obtained Characteristic.For example, especially when obtaining regulation information based at least two optical characteristics obtained by objective determination, due to Deviation is produced between optical characteristics and is difficult to compare, therefore this technology is more efficient.

For example, when obtaining regulation information, the output regulation information of control unit 70.In the present embodiment, for example, control unit 70 To sending regulation information for correcting the setup unit that the correcting value of adjustment state change is set.In addition, in this implementation In mode, it is setup unit that control unit 70, which doubles as,.Certainly, set as the structure different from control unit 70 or separately The structure of setup unit (setting control unit).In addition, in the present embodiment, as the structure of output regulation information, enumerate to Setup unit illustrates exemplified by sending the structure of regulation information, but is not defined in this.For example, it is also possible to regulation information is shown It is shown in monitor 4.Moreover, for example, it is also possible to print regulation information.In this case, scrutineer can be by confirming to monitor Device 4 or printed matter and confirm adjustment state.

For example, in the present embodiment, control unit 70 is used for determining list by subjective formula based on regulation information to set The correcting value that the adjustment state change of caused tested eye is corrected during member subjectively determines the optical characteristics for being detected eye. For example, control unit 70 is controlled correction optical system 60, the correcting value based on setting, enter to be about in subjective formula determination unit The correction (S6) that the adjustment state change of caused tested eye is offset.In addition, as being used for into being about in subjective formula determination unit The structure for the correction that the adjustment state change of caused tested eye is offset, is not defined to correct optical system 60.Can be separately The structure of the optical system of different corrections is set.

For example, control unit 70 sets correcting value based on acquired adjustment state.For example, control unit 70 is to correcting optics System is controlled.For example, correcting value can be made for regulation information each parameter and form set in advance, it is made Form can be stored in memory (for example, memory 72).In this case, for example, control unit 70 can be from memory 72, which recall correcting value corresponding with adjustment state, is set.Moreover, for example, on correcting value, can be deposited in memory 72 The arithmetic expression of the correcting value of each parameter for exporting regulation information is stored up, and correcting value is obtained using arithmetic expression.

For example, the correction state of correction optical system when control unit 70 determines for subjectivity is corrected.For example, control Portion 70 carries out the correction of additive correction amount.For example, the spherical degree of the correction optical system when subjectivity determines is 2.0D and tune In the case that the spherical degree of section information is 1.0, correcting value is set as 1.0D.For example, control unit 70 is with 1.0D pairs of correcting value The spherical degree of correction optical system 60 is corrected.That is, control unit 70 corrects optical system 60 by controlling, so that correction light The spherical degree of system is corrected as 1.0D mode.

In addition, in the present embodiment, enumerate and enter to be about to the school that the adjustment state change of tested eye is offset based on regulation information It is illustrated exemplified by positive structure, but is not defined in this.For example, it is also possible to it is to judge to adjust information based on regulation information It is no good, and result of determination is shown in monitor 4 or printed matter.In this case, scrutineer can confirm that result of determination, And carry out processing corresponding with result of determination.For example, scrutineer can carry out the action for improving adjustment state.

As previously discussed, for example, in the present embodiment, the light of tested eye is subjectively being determined by subjective formula determination unit During learning characteristic, the optical characteristics of tested eye is objectively determined by objective type determination unit, thus, it is possible to confirm subjective survey The change of the optical characteristics of tested eye in a period of fixed.Thus, scrutineer is it can be considered that tested eye in during subjective measure Optical characteristics change and carry out subjective measure.Therefore, scrutineer, can when subjectively determining the optical characteristics of tested eye Accurately determine the optical characteristics of tested eye.

In addition, for example, in the present embodiment, objectively determine and obtain the first optical characteristics, and determined subjectively The second optical characteristics objectively determined is obtained during the optical characteristics of tested eye.Obtain special based on the first acquired optics The regulation information of property and the second optical characteristics, and export regulation information.By such structure, according to first based on tested eye The regulation information of optical characteristics and the second optical characteristics, it can easily obtain the optical characteristics of the tested eye during subjectivity determines Change.Therefore, scrutineer, can be easily and high when subjectively determining the optical characteristics of tested eye by using regulation information Determine to precision the optical characteristics of tested eye.

In addition, for example, in the present embodiment, the optical characteristics of tested eye is subjectively being determined by subjective formula determination unit Before, the optical characteristics of tested eye is objectively determined by objective type determination unit.Thus, based on subjective formula determination unit The measure of objective type is carried out before subjectivity measure, therefore can inhibited due to the caused light using subjective formula determination unit The optical characteristics of the measure of objective type is obtained in the state of the change of characteristic.Optical characteristics is inhibited therefore, it is possible to obtain The optical characteristics of the measure based on objective type of change, can obtain better regulation information.

In addition, for example, in the present embodiment, regulation information is obtained by comparing processing, thus, after processing is compared Regulation information, can more easily obtain the change of the optical characteristics of tested eye during subjective measure.Therefore, scrutineer is led to Cross using regulation information, can be easier when subjectively determining the optical characteristics of tested eye and accurately determine tested eye Optical characteristics.

In addition, for example, in the present embodiment, based on regulation information come set for the adjustment state for being detected eye is changed into The correcting value of row correction, and enter to be about to support in the adjustment state change for being detected eye caused by subjective formula determination unit based on correcting value The correction to disappear.Thus, during the optical characteristics of tested eye is subjectively determined by subjective formula determination unit, even in generation During the change of the optical characteristics of tested eye, it can be also measured in the state of the change of optical characteristics is offset.Thus, When subjectively determining the optical characteristics of tested eye, the optical characteristics of tested eye can be easily and highly accurately determined.

For example, in the present embodiment, subjective formula optometry equipment 1 can start tested eye by subjective formula determination unit Optical characteristics subjective measure after, carry out objective determination, the measurement result of acquirement be set as determining by subjective formula single The initial value of correction optical system 60 during the optical characteristics of first tested eye of subjectively measure.

Fig. 7 is the flow chart of the flow of the control action for the initial value setting for illustrating the present embodiment.Hereinafter, initial value is illustrated Setting.For example, control unit 70 starts subjective measure (S11).For example, work as by scrutineer's performance monitor (in the present embodiment, As for operating portion) 4 when, for example, control unit 70 is controlled to display 31, required eyesight value is shown in optical axis L 2 Sighting target.

For example, control unit 70 determines it in the subjectivity for the optical characteristics for having started tested eye by subjective formula determination unit Afterwards, the optical characteristics of tested eye is objectively determined by objective type determination unit to obtain the optical characteristics of tested eye (S12).Example Such as, in the present embodiment, after control unit 70 presents initial presentation sighting target on the display 31, objective type determination unit is passed through Objectively determine the optical characteristics of tested eye and obtain the optical characteristics of tested eye.I.e., in the present embodiment, determined as subjectivity The timing of beginning, use the timing that initial presentation sighting target is presented.Certainly, the timing started as subjective measure, be not defined to be in The timing of sighting target is now initially presented.

For example, the timing started as subjective measure, as long as the state that the control of subjective measure starts.For example, The timing started as subjective measure, can be start to check the timing of program, start subjective determination device 1 monitor ( In present embodiment, as operating portion) 4, in the timing of driving of correcting optical system 60 etc. at least any one.

For example, the optical characteristics of the tested eye objectively determined is set as by subjective formula determination unit by control unit 70 The subjectively initial value (S13) of the correction optical system 60 during the optical characteristics of the tested eye of measure.For example, in the present embodiment, As the optical characteristics set for initial value, eye ametropia force can be enumerated (for example, spherical degree, astigmatism degree, astigmatism shaft angle Degree) exemplified by illustrate.In addition, in the present embodiment, as the optical characteristics set for initial value, enumerating eye ametropia force is Example illustrates, but is not defined in this.Can be different optics for example, as the optical characteristics for initial value setting Characteristic.Moreover, for example, as the eye ametropia force for initial value setting, spherical degree, astigmatism degree and astigmatism axle can be used It is at least any of in angle.

For example, in the present embodiment, control unit 70 is by the light of the tested eye objectively determined by objective type determination unit It is the quilt implemented before the objective determination based on objective type determination unit starts by subjective formula determination unit to learn property settings Examine the initial value of the correction optical system in the subjective measure (S11) of the optical characteristics of eye.It is in addition, single being determined by objective type During member obtains the optical characteristics of tested eye, it can continue to implement subjective measure.Moreover, passing through objective type determination unit During the optical characteristics for obtaining tested eye, subjectivity measure can temporarily cease.In such a case, it is possible to initial value is set, And control unit 70 starts again at subjective measure.Moreover, in such a case, it is possible to after initial value is set, pass through inspection People is looked into select to start the switch of subjective measure and start again at subjective measure.

For example, control unit 70 obtains the eye ametropia force of tested eye by objective type determination unit.Taken for example, control unit 70 is worked as When must be detected the eye ametropia force of eye, correction optical system 60 is driven based on eye ametropia force, and be set as the initial of subjective determination Value.For example, by objective type determination unit, based on the eye ametropia force of tested eye, in a manner of correcting the refractive error of tested eye Control correction optical system 60.

For example, when control correction optical system 60 completes the setting of initial value, scrutineer sets from completion initial value Fixed state starts, and using monitor 4, the correction number of degrees of optical system 60 are corrected in change, obtain the subjective optics of tested eye Characteristic (S15).That is, subjective measure is proceeded by from the state for the setting for completing initial value.

For example, in the present embodiment, surveyed having started the subjective of the optical characteristics of tested eye by subjective formula determination unit After fixed, the optical characteristics of tested eye is objectively determined by objective type determination unit to obtain the optical characteristics of tested eye.Will The optical characteristics of the tested eye objectively determined is set as that the optics that tested eye is subjectively determined by subjective formula determination unit is special The initial value of correction optical system during property.Pass through such structure, it is not necessary to standby real again untill completing objective determination Alms giver sees the subjective measure of check device, can promptly determine the optical characteristics of tested eye.

In addition, for example, in the present embodiment, the optics of the tested eye objectively determined by objective type determination unit is special Property be set as before the objective determination of objective type determination unit starts by subjective formula determination unit implement tested eye light Learn the initial value of the correction optical system in the subjective measure of characteristic.By such structure, can promptly carry out based on master See the subjective measure of check device.

In addition, in the present embodiment, the optical characteristics for enumerating the tested eye that will objectively determine is set as surveying in objective type In the subjective measure of the optical characteristics for the tested eye that the objective determination of order member is implemented before starting by subjective formula determination unit Correction optical system initial value structure exemplified by be illustrated, but be not defined in this.For example, control unit 70 is passing through Subjective formula determination unit performs the first subjective measure of the optical characteristics for subjectively determining tested eye and then secondary passes through subjectivity Formula determination unit performs the second subjective measure of the optical characteristics for subjectively determining tested eye.Control unit 70 is starting the first master After observation is fixed, the optical characteristics of tested eye is objectively determined by objective type determination unit.Control unit 70 will be surveyed by objective type The optical characteristics for the tested eye that order member objectively determines is set as the initial value of the second subjective measure.In addition, for example, first Subjectivity measure is to obtain the measure of the optical characteristics different from the optical characteristics obtained by the second subjective measure.In such case Under, for example, the first subjective measure can the optical characteristics of sighting target light beam is changed by correcting optical system Subjective measure without the optical characteristics that tested eye is subjectively determined under correction state.That is, the first subjective measure can be bore hole inspection Look into.For example, the second subjective measure can be by the correction optical system make the changes in optical properties of the sighting target light beam and Subjectively determine the subjective measure of the optical characteristics of tested eye.

For example, in the present embodiment, the optics spy for being detected eye is subjectively determined being performed by subjective formula determination unit Property the first subjective measure and then secondary the of the optical characteristics that subjectively determines tested eye is performed by subjective formula determination unit Two subjective measure.After the first subjective measure has been started, the optics of tested eye is objectively determined by objective type determination unit Characteristic, and the optical characteristics of the tested eye objectively determined is set as the second subjective initial value determined.By such Structure, in the case of subjective measure is carried out again, due to having been achieved with initial value in different subjective measure, therefore Can promptly it be measured.
