Abstract
Description
Technical Field
[0001] The present application relates to the technical field of visual function training, and more specifically, to a myopia visual function examination and training device. Background Art
[0002] Visual function testing and training often involves using an eye chart light box. The different sight marks on the light box can be adjusted by varying the distance and size. For example, having the patient observe the sight marks on the light box at different distances causes the ciliary muscles to contract and relax, thereby improving the eye's ability to adjust. This can be helpful in improving refractive errors such as myopia and hyperopia.
[0003] Existing eye chart light boxes have uniform specifications and fixed screen sizes, which have certain limitations in practical applications. When it comes to vision training, the training content is monotonous because there are not enough sight marks presented at the same time. The trainee's eye movement path and visual stimulation pattern will be relatively limited, which affects the continuity and advancement of the training, making it difficult to comprehensively improve scanning ability, prolonging the time required to achieve training results, and reducing training efficiency.
[0004] Application Contents
[0005] In order to solve the above problems, the present application provides a myopia visual function examination and training device.
[0006] The present application provides a myopia visual function examination and training device that adopts the following technical solutions:
[0007] A myopia visual function test and training device comprises a light box and a box body, wherein the box body is located inside the light box, a vision chart is provided on one side of the box body, extension components are provided inside and on both sides of the box body, and an adjustment component is provided inside the light box;
[0008] The extension component includes an extension plate, and an extension table is provided on one side of the two extension plates. The two extension plates are rotatably connected to the two sides of the light box respectively. The two extension plates are used to expand the training screen of the light box when training vision.
[0009] Furthermore, two extension plates are respectively located on both sides of the light box, and the sizes of the two extension plates match the size of the vision chart plate.
[0010] Furthermore, threaded holes are provided on both sides of the inner wall of the light box, a fixing block is fixedly connected to one side of each extension plate, and a screw is provided inside each fixing block.
[0011] Furthermore, each threaded hole is respectively arranged corresponding to the fixing block, and each screw rod respectively passes through the corresponding fixing block and is threadedly connected to the corresponding threaded hole.
[0012] Through the above technical solution, the training screen can be expanded. After the screen is expanded, more sight marks of different specifications can be displayed, and the intervals between the sight marks can also be adjusted more flexibly.
[0013] Furthermore, the adjustment component includes a grid-type track, which is fixedly installed on the inner wall of the box body.
[0014] Furthermore, first strip rails are provided on both sides of the grid rail, and the two first strip rails are respectively located at the bottom of the corresponding extension plates.
[0015] Furthermore, a second strip track is provided on one side of the inner wall of each extension plate, and multiple lamp bodies are provided on one side of each second strip track, first strip track and grid track. Multiple track joints are opened inside each second strip track, first strip track and grid track, and the track joints are evenly distributed.
[0016] Furthermore, the bottoms of the multiple lamp bodies are slidably connected to the second strip track, the first strip track and the grid track. The bottom of each lamp body is provided with a conductive contact, and each conductive contact is respectively engaged with the corresponding track connector.
[0017] Through the above technical solutions, the personalized training needs of different vision levels can be met and the training methods can be enriched.
[0018] In summary, this application includes at least one of the following beneficial technical effects:
[0019] (1) This application can expand the training screen by extending the components. After the screen is expanded, more sight marks of different specifications can be displayed, and the intervals between sight marks can be adjusted more flexibly. This allows the eyes to be trained in a richer visual stimulation environment, which helps to improve the training effect of visual sensitivity and can also train binocular vision function. Binocular vision function training often requires presenting different visual stimuli to both eyes at the same time. The extended light box screen can better display complex binocular sight marks, such as stereo sight marks, fusion sight marks, etc.
[0020] (2) This application controls the number of lamps by adjusting the components. For people who cannot bear the visual stimulation brought by more lamps at the beginning, the training intensity can be reduced by reducing the number of lamps, so that they can train step by step. For those with better vision, the number of lamps can be increased to increase the difficulty of training, so as to meet the personalized training needs of different vision levels, enrich the training methods, and combine multiple training modes.

DETAILED DESCRIPTION
[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application; obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments of the present application, and all other embodiments obtained by those skilled in the art based on the embodiments in the present application without creative labor fall within the scope of protection of the present application.
[0030] Referring to Figure 1-Figure 5 , a myopia visual function examination and training device includes a lamp box 1 and a box body 2, the box body 2 is located inside the lamp box 1, one side of the box body 2 is provided with a visual chart plate 3, the inside of the box body 2, both sides of the box body 2 are provided with an extension assembly, the inside of the lamp box 1 is provided with an adjusting assembly;
[0031] The extension assembly includes an extension plate 4, one side of each of the two extension plates 4 is provided with an extension chart 5, the two extension plates 4 are respectively rotationally connected to the two sides of the lamp box 1, and the two extension plates 4 are both used to expand the training screen when training vision.
[0032] Referring to Figure 1-Figure 5 The two extension plates 4 are respectively located on both sides of the light box 1. The sizes of the two extension charts 5 match the size of the vision chart plate 3. Threaded holes 8 are provided on both sides of the inner wall of the light box 1. A fixing block 6 is fixedly connected to one side of each extension plate 4. A screw 7 is provided inside each fixing block 6. Each threaded hole 8 is respectively arranged corresponding to the fixing block 6. Each screw 7 passes through the corresponding fixing block 6 and is threadedly connected to the corresponding threaded hole 8.
[0033] The extension component can be used to expand the training screen during training. The specific operation method is that when the training screen needs to be expanded, since the two extension plates 4 are rotatably connected to the two sides of the light box 1 respectively, the two extension plates 4 can be rotated out from the two sides of the light box 1. Because the sizes of the two extension charts 5 match the size of the vision chart board 3, and an extension chart 5 is provided on one side of the two extension plates 4, the rotated extension plate 4 can expand the training screen of the light box 1 through the extension chart 5 on one side, thereby meeting the demand for a larger training screen when training vision, and then screw the screw 7 inside each fixing block 6 into the corresponding threaded holes 8 on both sides of the inner wall of the light box 1 to achieve fixation.
[0034] The training screen can be expanded by extending the component. After the screen is expanded, more sight marks of different specifications can be displayed, and the intervals between sight marks can also be adjusted more flexibly. This allows the eyes to be trained in a richer visual stimulation environment, which helps to improve the training effect of visual sensitivity and can also train binocular vision function. Binocular vision function training often requires presenting different visual stimuli to both eyes at the same time. The extended light box 1 screen can better display complex binocular sight marks, such as stereo sight marks, fusion sight marks, etc.
[0035] Reference Figure 1-Figure 5 The adjustment component includes a grid track 9, which is fixedly mounted on the inner wall of the box body 2. A first strip track 11 is provided on both sides of the grid track 9. The two first strip tracks 11 are respectively located at the bottom of the corresponding extension plate 4. A second strip track 12 is provided on one side of the inner wall of each extension plate 4. A plurality of lamp bodies 10 are provided on one side of each second strip track 12, first strip track 11 and grid track 9. A plurality of rail joints 13 are provided inside each second strip track 12, first strip track 11 and grid track 9. The rail joints 13 are evenly distributed. The bottoms of the plurality of lamp bodies 10 are slidably connected with the second strip track 12, first strip track 11 and grid track 9. A conductive contact 14 is provided at the bottom of each lamp body 10, and each conductive contact 14 is respectively engaged with the corresponding rail joint 13.
[0036] By adjusting the assembly, the number of lamp bodies 10 can be controlled to adjust the different intensities of training. The specific operation method is that since the bottom of each lamp body 10 is connected to the corresponding track joints 13 on the second strip track 12, the first strip track 11 and the grid track 9 through the conductive contacts 14, and the lamp body 10 is slidably connected to these tracks, when the training intensity needs to be adjusted, that is, the number of lamp bodies 10 is changed, the lamp body 10 can be manually slid along the second strip track 12, the first strip track 11 or the grid track 9. During the sliding process, the conductive contacts 14 at the bottom of the lamp body 10 will be disengaged from the track joints 13 or connected to the new track joints 13. If you want to increase the training intensity, you can connect more lamp bodies 10 to the track joints 13 through the conductive contacts 14 to increase the number of lamp bodies 10 participating in the training; conversely, if you want to reduce the training intensity, some lamp bodies 10 will be detached from the track joints 13 to reduce the number of lamp bodies 10 participating in the training.
[0037] By adjusting the components to control the number of lamp bodies 10, for people who cannot initially withstand the visual stimulation brought by more lamp bodies 10, the training intensity can be reduced by reducing the number of lamp bodies 10, allowing them to train step by step. For trainees with better eyesight, the number of lamp bodies 10 can be increased to increase the difficulty of training, thereby meeting the personalized training needs of different vision levels, enriching the training methods, and combining multiple training modes.
[0038] Working principle: When the training screen needs to be expanded, since the two extension plates 4 are rotatably connected to the two sides of the light box 1 respectively, the two extension plates 4 can be rotated out from the two sides of the light box 1. Because the sizes of the two extension charts 5 match the size of the vision chart board 3, and one side of the two extension plates 4 is provided with an extension chart 5, the rotated extension plate 4 can expand the training screen of the light box 1 through the extension chart 5 on one side, thereby meeting the demand for a larger training screen when training vision, and then screw the screw 7 inside each fixing block 6 into the corresponding threaded holes 8 on both sides of the inner wall of the light box 1 to achieve fixation.
[0039] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
