Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to an optometry system that includes an objective optometrist (autorefractometer) and a subjective optometrist (vision tester) used in optometry on a table.

[Conventional technology]

At eyeglass stores and the like, after a visual acuity test, it is common practice to provide consulting in order to select eyeglass frames, lenses, and the like. When performing this visual acuity test, both a subjective ophthalmoscope (autorefractometer) and an objective ophthalmoscope (vision tester) are usually used. Testing using this subjective ophthalmoscope allows for accurate measurements, but if you do not know the visual acuity of the eye to be tested before the test, it may be difficult to determine which power lens should be inserted before starting the test. It takes a lot of time because you don't know. Moreover, when the eye examination time becomes longer in this way, the degree of fatigue increases and the eye examination accuracy decreases. Furthermore, the objective ophthalmoscope can measure the refractive power of the subject's eye to a certain extent very quickly, regardless of the subject's will. Therefore, by determining the refractive power (refractive power, astigmatic power, and astigmatic axis) of the eye to be examined in advance using an objective ophthalmoscope, it is possible to determine what lens power should be used during the examination using a subjective ophthalmoscope. Once started, it will give you an idea of whether you can perform a subjective test in a short time. Therefore, in a visual acuity test, the refractive power of the eye to be examined is first tested using an objective ophthalmoscope, and then a test using a subjective ophthalmoscope is performed based on this data. In particular, in the case of severe astigmatism, unless a certain degree of astigmatism is corrected, visual acuity may not be measurable no matter what refractive power lens is used. For this reason, the eye examination is started after a lens with the astigmatic power and astigmatism axis measured by the objective ophthalmoscope is inserted in advance into the position where the eye to be examined looks. After the refractive power to be corrected is determined, the astigmatism test is performed, and the subjective astigmatic power and astigmatism axis are determined. In addition, in the case of children and elderly people who are not familiar with optometry,
There is a risk of ambiguous judgment and overcorrection, and the results of objective tests can be helpful in preventing this. Currently, such ophthalmoscopes are installed separately in different locations. Moreover, in many cases, eyeglass stores do not have a large space, so when arranging a plurality of ophthalmoscopes and consulting tables, it is often difficult to arrange them. Furthermore, since the final check is performed using a trial frame, it must be carried out in a space that can accommodate multiple trial lenses. Furthermore, in this case, it would be good to be able to select frames, etc. while watching the condition for a while by playing a trial frame. Furthermore, in order to select eyeglass frames and lenses, materials such as pamphlets and catalogs of eyeglass frames and lenses are spread out on the table, and the customer (examiner) and store staff (examiner) look at these materials. Consulting is often involved. Since this kind of consulting involves a lot of materials, it is often done while the customer and staff are pointing at a catalogue, etc., so it is best to do it sitting in the middle of the table.

[Problem to be solved by the invention]

However, these subjective ophthalmoscopes, objective ophthalmoscopes, trial lenses, etc. are currently installed separately in different locations, so it is difficult for examiners and patients to move from one place to another. It was not possible to perform optometry at such places. Therefore, the present invention is capable of performing a visual acuity test using an objective ophthalmoscope and a subjective ophthalmoscope without moving the examiner and the examinee while sitting at positions sandwiching the center of the table. After the examination, the examiner and the patient do not have to move, just move the ophthalmoscope to the side of the table, and perform a final check using the trial frame or provide consultation while showing the materials spread out on the table with the center of the table in between. The aim is to provide an optometry system that can perform

[Means to solve the problem]

In order to achieve this purpose, the optometry system of the present invention moves an objective ophthalmoscope and a subjective ophthalmoscope used for eye examination between a retracted position excluding the area in front of the subject's eyes and an eye examination position above the center of the table. It is also characterized by the provision of an optometry table.

【Example】

The present invention will be explained below based on the drawings. 1 and 2 are diagrams of an optometry system showing a first embodiment of the present invention. First, the configuration will be described. In the figure, 1 is a chair on which a subject sits, and 3 is an optometry table installed in front of the chair 1. Reference numeral 10 denotes a mounting table, which is composed of a frame 11 and a carrier 15. The frame 11, which has a disk shape, has a horizontal axis 11a.
It is rotatably attached to. This frame 11
A plurality of carriers 15 having rotatable support points 13 spaced apart from each other are provided on the same circumference sufficiently far from the center of the carrier. The carrier 15 has a substantially L-shaped cross section,
A groove-like guide rail 15b is provided on the horizontal carrier table 15a, and instruments 7 such as a refractometer (objective ophthalmoscope) and a vision tester (subjective ophthalmoscope) are placed on the movable table 5. There is. This is done by fixing the instrument 7 on the moving table 5 with bolts or the like as shown in FIG.
A moving table 5 is mounted so that its wheels 9 are guided by guide rails 15b of a carrier table 15a. Further, a stopper (not shown) is provided to prevent the movable table 5 from moving except when pulled out to the optometry table 3. In this way, the carrier 15 always supports the instruments 7 horizontally, and the mounting table arranges the instruments 7 in a vertical plane. A moving means for moving and setting the instrument 7 to the examination position at the center of the table, that is, in front of the subject's eyes, is composed of a moving table 5 and a rail 3a provided on the optometry table 3. The frame 11 does not need to be disc-shaped and may be radial. However, here, the disc-shaped frame 11 is used as a driven vehicle that receives driving force. That is, a chain, a rope, a belt, or the like is hung on the frame 11 as a driven vehicle, which is attached to a motor vehicle 21 connected from a motor 17 via a gearbox 19. Note that the frame 11, carrier 15, instrument 7, etc. are housed in the housing 23 in the retracted position shown by the two-dot chain line. A method of using the optometry system having such a configuration will be explained. After the operator seats the subject on the chair 1, the operator takes out the instrument 7 from the housing 23 according to the examiner's needs. Therefore, when a switch (not shown) is pressed, the motor 17
is driven, and the decelerated prime mover 21 is attached to the frame 11.
Rotate. The instrument 7 on the carrier 15, which is suspended from the frame 11 via the fulcrum 13, is always supported horizontally and passes in front of the optometry table 3. At this time, the rotation of the frame 11 is stopped so that the desired instrument 7 corresponds to the optometry table 3, and the rail 3a of the optometry table 3 and the rail 15b of the carrier table 15a are aligned. In this state, the moving table 5 on the carrier table 15a is
It becomes possible to move left and right on the optometry table 3 along the line a. Therefore, in this state, the stopper (not shown) is removed, and the instrument 7 is pulled out onto the optometry table 3, and the movable table 5 is pulled out and installed on the rail 3a above the center of the optometry table 3. When the use of this instrument 7 is finished, by moving the instrument 7 on the optometry table 3 toward the housing 23, the instrument 7 is placed on the carrier table 15a and stored in the retracted position on the side of the optometry table 3. . Furthermore, when it is desired to use another instrument 7, the same procedure can be followed. 3 and 4 are diagrams of an optometry system showing a second embodiment of the present invention. In the drawings, parts or members that are the same or equivalent to those in the first embodiment are given the same reference numerals and redundant explanations will be omitted. First, this configuration will be explained. Reference numeral 30 denotes a mounting table, which has four pillars 31 inside the housing 23.
The case 33 moves up and down while being guided by the case 33, and has at least two partitioned spaces 25 formed therein for arranging and storing the instruments 7 in a vertical plane. Although the case 33 has an open shape in this figure, it may be open only on the optometry table 3 side and close off the rest. Four rollers 35 provided on the side of the case 33 are guided by the pillars 31, and can move up and down. In addition, the case 33 has two pulleys 3
The balance is adjusted by a counterweight 43 that is suspended from a rope 41 that is strung through cables 7 and 39. A motor 17 is connected to a pulley 39 around which a rope 41 is wound according to the required driving force, and moves the case 33 up and down. A method of using the optometry system having such a configuration will be explained. This method of use is almost the same as that of the first embodiment, except that the apparatus stand does not rotate as in the first embodiment, but moves up and down within a vertical plane. Therefore, in order to take out the desired instrument 7, the motor 17 is driven to move the case 33 up and down, the desired instrument 7 is aligned with the optometry table 3, and the same as in the first embodiment is used to pull out the desired instrument 7. .
To replace with another instrument 7, proceed in the same manner. In addition, in the first and second embodiments, the instrument 7
In order to smoothly place the optometry table 3 on the optometry table 3, the gap between the optometry table 3 and the carrier 15 or the case 33 must be made very narrow, the optometry table 3 must be made movable, or the carrier 15 must be placed on the optometry table 3. This can be achieved by allowing movement to the side. Instead of placing the optometry instrument 7 on the carrier table 15a via the movable table 5, the carrier table 15a is configured to be extendable in a direction perpendicular to the frame 11, that is, in the horizontal direction, and the optometry instrument 7 is placed directly on the table. It is also possible to have a configuration in which it is attached.

【composition】

Since the present invention is configured as described above, the examiner and the subject can perform visual acuity tests using an objective ophthalmoscope and a subjective ophthalmoscope without moving while sitting on opposite sides of the center of the table. It can be carried out. Moreover, by providing the subjective ophthalmoscope and the objective ophthalmoscope on the table in this way, the objective ophthalmoscope and the subjective ophthalmoscope can be connected with short wiring within the table for data transmission. Optometric data (refractive power) obtained in a short time by the objective ophthalmoscope can be easily and quickly supplied to the subjective ophthalmoscope to control the initial settings of the lenses of the subjective ophthalmoscope. In addition, after the visual acuity test, the examiner and patient do not have to move, just move the ophthalmoscope to the side of the table, and the final check can be performed using the trial frame or the materials spread out on the table can be shown with the center of the table in between. Consulting can be done while doing so.
