Then, explain in having the eye detection device of structure as stated, will make or the inspection sighting target prepared is presented at operation and the making of eye examination program on the Optotype presenting apparatus 200 by the examiner.
The example of the inspection sighting target of being made by the examiner at first, is described.Fig. 5 (a) is spherical degree adjustment with intersecting the example of grid sighting target 300, is formed by five vertical lines 301 and five horizontal lines 302 of black, and background is to be made up of white background.When inspection, configuring fixed crossing cylinder eyeglass on the inspection hatch 11 of determination unit 10 is adjusted spherical degree through the definition of seeing vertical line 301 and horizontal line 302.
Fig. 5 (b) is the example of the strabismus checking sighting target 310 in the two eye vision functional checks.Last vertical line 311a and right horizontal line 311b describe with green, and following vertical line 312a and left horizontal line 312b describe with redness.And the round 313a of central authorities, the line 313b and the housing 313c of four direction sideling describe with black.In when inspection, on the inspection hatch 11 of left eye, dispose green color filter, on the inspection hatch 11 of right eye, dispose Red lightscreening plate, check stravismus through the skew of each line of independently identifying with right eye and left eye.
Fig. 5 (c) is the example of two balance check sighting targets 320.Use when waiting,, replace literal or mark and describe five caricature sighting targets 321 that the child can interpretation in the central authorities of sighting target 320 for child that can not the interpretation literal in inspection etc.It is to be 0.3,0.5,0.7,1.0 according to being equivalent to the vision value that the size of 5 caricature sighting targets 321 begins from a left side, and 1.2 size is described.During inspection, if at the prism (the prism number of degrees 3) of right eye configuration bottom lower direction, the prism (the prism number of degrees 3) of direction is then discerned sighting target 320 up and down discretely in two on left eye configuration bottom.
The image editing software that the inspection sighting target of being made by the examiner like this can use a computer and sell on the market that PC has is made as view data.The situation of the intersection grid sighting target 300 of construction drawing 5 (a) is described as an example.Suppose sighting target suggestion device 200 (display 201) is arranged at and leave hypermetropia inspection from those who are investigated and use apart from 5m.In addition, suppose that display 201 is picture dimensions of 19 inches with dot structure of 1280 * 1024 (horizontal * vertical) pixel, one of them pixel is to be the square of 0.294mm on one side.In addition, suppose on the display 201 that is positioned over 5m inspection distance, to hope that the size of the intersection grid sighting target 300 of demonstration is that the length of the vertical line that vertical line 301 has is 180mm, and live width is 1.8mm.The interval W of line (inner distance of line and line) is 25.2mm.At this moment, because the size of a pixel of display 201 is to be 0.294mm on one side, so the 1.8mm * 180mm (horizontal * vertical) in order to realize vertical line 301 becomes the dot structure of about 6 * 612 (horizontal * vertical).25.2mm for the interval W that realizes line becomes about 86 pixels.Horizontal line 302 is that vertical line 301 is revolved the position relation that turn 90 degrees, the length of its line, live width and line be the structure identical at interval with vertical line 301, so dot structure also is suitable for identical calculating.
Describe the mode of the identical sighting target of above-mentioned dot structure, the view data of making sighting target 300 through using the image editing software that is installed on the personal computer PC of selling on the market with this dot structure.That is,, can for the interval between line and the line, can be the structure of 86 pixels for about 6 * 612 (horizontal * vertical) dot structure for the single line of vertical line 301.In addition, for of view data, if be made as the dot structure of 1280 * 1024 (horizontal stroke * height) pixel identical with display 201, then with living pictorial display on display 201.
In addition, shown in Fig. 5 (c), when making the sighting target 321 corresponding, be benchmark with Lan Shi (Landolt) sighting target of when checking, stipulating apart from 5mm with vision value sighting target, confirm the actual size of sighting target 321.For example, inspection distance is that 0.3 Lan Shi sighting target is the size of 24.24mm * 24.24mm for 5mm and vision value, at this moment, through describe sighting target 321 with the dot structure of 82 * 82 pixels, can make the sighting target that is equivalent to vision value 0.3.The sighting target 321 that is equivalent to other vision value 0.5,0.7,1.0,1.2 is also made according to same thought.
The view data of the inspection sighting target of being made by the examiner as stated can store into through the write-in functions that computer PC had among the storage medium CF.As the preservation form of examiner to storage medium CF image stored data, if for example preserve as the packed data of general requirements such as JPEG, then can the conserve memory capacity.In addition, when in storage medium CF, storing the sighting target data of examiner's preparation, different ground with the memory area of the pre-prepd sighting target data of manufacturer's side are stored in the file of preparing as the memory area that increases sighting target.Thus, confusing of the sighting target data of avoiding preparing with the manufacturer side can reduce the problem of the sighting target data of being prepared by examiner's (user) deletion or change manufacturer side.As stated, if outside the sighting target data that the storage examiner prepares in storage medium CF, also store the sighting target data that manufacturer's side is prepared, during the combination etc. of then after device is provided with, changing sighting target conveniently, but not necessarily.
At this, when the control assembly 210 that receives the command signal (communication cryptology) that shows from the sighting target of operating unit 20 shows sighting target on display 201, need to specify which sighting target of demonstration.Therefore, the sighting target difference that sighting target that is increased newly by the examiner and manufacturer prepare is come, and specifies through the regulation filename that manufacturer is provided with in advance.That is, when the examiner arrives storage medium CF in the inspection sighting target storage (preservations) that will newly make (or prepare), will give each the sighting target data and preserve by the regulation filename that manufacturer makes an appointment.Filename for example be decided to be approximately " K001 ", " K002 ", " K003 " ..., " K018 ".Below, suppose to give filename " K001 " to the inspection sighting target 300 of Fig. 5, give filename " K002 " to inspection sighting target 310, give filename " K003 " to inspection sighting target 320.
When storage medium CF was set at the slot 203 of sighting target suggestion device 200, control assembly 210 was read the sighting target data that the manufacturer in the manufacturer's memory area that is stored in storage medium CF in advance prepares, and it is copied to memorizer 205.And, also can call the sighting target data of the examiner's making that is stored in the memory area (file) of distributing to user and using, and it is copied to memorizer 205.When the processing speed of the image processing function of control assembly 210 is fast, also can copy in the memorizer 205, but when sighting target shows, call the sighting target data and show sighting target at display 201 from storage medium CF.
Using the inspection sighting target of preparing by the examiner as stated when Optotype presenting apparatus 200 shows (during manual examination (check)); The examiner operates operating unit 20; When touching the No.4 icon of label icon 87; Shown in Fig. 4 (b), the display frame of display 22 is switched to demonstration and is used to select the increase sighting target options button 86b by the sighting target of examiner's increase.Increase sighting target options button 86b preparation the key that has added " 1 "～" 18 " numberings is arranged.Following agreement is arranged: select the sighting target of numbering " 1 " corresponding to file " K001 " by name; Select the sighting target of numbering " 2 " corresponding to file " K002 " by name; Select the sighting target of numbering " 3 " corresponding to file " K003 " by name; After this, likewise select the sighting target of numbering " 18 " corresponding to file " K018 " by name.When in increasing sighting target options button 86b one is selected, control assembly 21 will send to sighting target suggestion device 200 with the idsplay order signal of the sighting target of options button corresponding file name.Control assembly 210 calls the sighting target data that are stored in the memorizer 205 (perhaps storage medium CF) according to filename, and should check that sighting target was shown on the display 201 according to the command signal that sends.The inspection sighting target is to consider Pixel Dimensions and the inspection distance of display 201 and make, and shows the inspection sighting target of the size that the examiner is desired thus.
Then, explain that the examiner formulates the flow process of checking process, the working condition that is presented at inspection sighting target and determination unit 10 on the Optotype presenting apparatus 200 at each examination phase of checking process is set to the eye examination program making function of eye examination program.Through the operation of Menu key 38, on the picture of display 22, show various setup menus, when wherein program writes menu when selected, eye examination routine call picture (omitting diagram) is shown on the display 22.For example, can register five eye examination program A, B, C, D, E.When for example calling program B through eye examination routine call picture, shown in Fig. 6 (a), the inspection item of this program B guide look picture 90a is shown on the display 22.The inspection item icon 120 that on this picture, shows the guide look of each stage put down in writing checking process and its contents of program.When program is not transfused to, show the inside of each icon 120 with empty hurdle.The digital 120a that shows in the left side of icon 120 is the inspection item numbering of the examination phase of expression eye examination process.When new production process, in order contents of program is programmed from 1 beginning of inspection item numbering.Page or leaf through page up icon 125a, following one page icon 125b image switching.When icon 120 is touched, so on display 22 the condition setting picture 90b shown in the displayed map 6 (b).
No.4 label icon is as the selectionbar of the inspection sighting target that increases newly and preliminary.When selecting No.4 label icon; Shown in Fig. 6 (c); Replace the selectionbar 93 of sighting target, the condition setting picture 90c (examiner's sighting target is provided with picture) that selects numbering " 1 "～" 18 " selectionbar 106 is arranged and switch to the preparation that is used to be provided with the sighting target that the examiner prepares.At this; Following agreement is arranged: select the sighting target of numbering " 1 " corresponding to file " K001 " by name; Select the sighting target of numbering " 2 " corresponding to file " K002 " by name; Select the sighting target of numbering " 3 ", after this, likewise select the sighting target of numbering " 18 " corresponding to file " K018 " by name corresponding to file " K003 " by name.
The demonstration example of Fig. 6 (b) is the situation that is provided with the inspection of spherical degree adjustment as the examination phase of inspection item numbering 1.In this case, if from sighting target selectionbar 93, choose by manufacturer pre-prepd red/green sighting target, then in display field 91, show the pattern of red/green sighting target.Hurdle 97 is set right eye is set as the inspection eye.The right eye side of auxiliary lens selectionbar 92 is set to open wide, and the left eye side is set to cover.Hurdle 94 is set is set to conscious inspection, the hurdle is set is set to the hypermetropia inspection, the hurdle that is provided with of checking mode is set to sphere adjustment modes (SPH).In addition, in this inspection, hurdle 98 is set is set to " cloud and mist+0.5 ", hurdle 99 is set is set to " not carrying out the XC test ".Respectively be provided with in the hurdle,, the project of examiner's expectation can be set through among touching the option of ejecting demonstration in each hurdle, selecting through touch.
At this, in the examination phase of spherical degree adjustment, suppose to replace the red/green sighting target of manufacturer's preparation, use the inspection sighting target 300 of Fig. 5 (a) of examiner's preparation to make the eye examination program.At this moment, through selecting the No.4 of label icon 104, switch to the picture that is provided with that preparation shown in Fig. 6 (c) is useful on the sighting target selectionbar 106 of selecting the inspection sighting target that the examiner prepares.Inspection sighting target 300 is stored among the storage medium CF with filename " K001 ".Therefore, through touching the numbering " 1 " of selecting sighting target selectionbar 106 by the examiner, and on the display field 91 of sighting target display file name " K001 ".Under the situation of the sighting target that manufacturer prepares; To the programme pattern of the sighting target that makes that on display field 91 demonstration is selected of control sequence; But under the situation of the sighting target that the examiner prepares, owing to do not know this pattern, so the numbering corresponding file name of demonstration and sighting target selectionbar 106.The examiner confirms according to the demonstration of the filename of display field 91 whether the sighting target of oneself wanting is set up.
If the stage during from production process begins to seek the interlock of the action of sighting target suggestion device 200, can confirm more reliably then whether the sighting target of oneself wanting is set up.That is, when the numbering of sighting target selectionbar 106 was selected, the command signal that the sighting target corresponding with this numbering shows sent to sighting target suggestion device 200 sides from the control assembly 21 of operating unit 20.When the command signal of sighting target demonstration is the numbering " 1 " of sighting target selectionbar 106; The control assembly 210 of sighting target suggestion device side calls the data of the sighting target 300 that is endowed and numbers " 1 " corresponding file name " K001 " from storage medium CF (or memorizer 205), and on display 201, shows this sighting target.Whether the examiner is the inspection sighting target of oneself wanting through watching the sighting target that is shown on the display 201 to confirm.In addition, when the sighting target data with the numbering corresponding file name of in sighting target selectionbar 106, choosing were not stored among the storage medium CF (or memorizer 205), control assembly 210 showed error message on display 201.Thus, can confirm the mistake that sighting target is selected in the stage at program making.
As stated, when red/green sighting target changed to the inspection sighting target 300 that the examiner prepares, in order with this inspection sighting target 300 determination unit 20 to be worked, the right eye side that examiner's auxiliary lens is provided with hurdle 92 was set to fixedly crossing cylinder eyeglass.Other is provided with hurdle 94～99 and likewise is provided with like the situation of Fig. 9 (b).
In addition; At examination phase as two balance checks, the sighting targets such as literal that replace manufacturer to prepare, and when using the inspection sighting target 320 of Fig. 5 (c); Through selecting the numbering " 3 " of the sighting target selectionbar 106 corresponding, inspection sighting target 320 is set with the filename " K003 " of this sighting target.Display file name " K003 " on display field 91.In this inspection, the examiner is provided with hurdle 92 with auxiliary lens and is set to two and opens wide, checking mode is provided with hurdle 96 is set to spherical degree adjustment (SPH), with the cloud and mist amount hurdle 98 is set and crossing cylinder test setting hurdle 99 is set to " nothing ".
