Problems solved by technology

However, wearing glasses can only temporarily alleviate the problem of insufficient vision, and has no ability to control the development of myopia, and even lead to the continuous deepening of myopia
[0003] A more advanced treatment for myopia is laser surgery that changes the refractive power of the cornea. However, such surgery is expensive and has certain risks, which may cause sequelae after surgery
Moreover, there is also the problem of recurrence of myopia in patients after surgery.

Embodiment 1

[0048] refer to Figure 1a , the present embodiment provides a comprehensive vision training system 100 , which includes a base plate 110 , a support 120 , a cover 130 , an optical lens set 140 , a first mirror 150 , a second mirror 160 and a third mirror 170 .

[0049] The supporting member 120 is column-shaped, and is fixed on the left end of the bottom plate 110 . The cover body 130 is fixed on the top of the supporting member 120 . The bottom surface of the cover body 130 begins with an incident light opening 131 . There is an exit light opening 132 on the left side of the cover body 130 . On the upper surface of the bottom plate 110, there is a placement area facing the incident light opening 131, and the reading material 200 is placed on the placement area.

[0050] The optical lens group 140 is disposed in the cover body 130 . The optical lens group 140 has an object-side end receiving light from the incident light opening 131 , and an image-side end leading the ligh...

Embodiment 2

[0064] This embodiment is basically the same as Embodiment 1, the difference is that, with reference to image 3 , the optical lens group 140 is different. A prism system 144 is set to adjust the direction of the image so that the image is upright so that the patient can watch it. The eyepiece 145 is set, and eyeglasses of different degrees, different types, and different quantities are selected for use according to the actual refractive condition of the patient.

[0065] Specifically, refer to image 3 , the optical lens set 140 sequentially includes a reflective lens set 146 , a prism system 144 and an eyepiece 145 from right to left.

[0066] The mirror set 146 includes a mirror A141 and a mirror B142. The mirror A141 constitutes the object-side end. The reflection mirror A141 is located above the incident light opening 131 , and the reflection surface of the reflection mirror A141 faces obliquely downward to the left. The reflector B142 is located obliquely below the ...

Embodiment 3

[0074] refer to Figure 4 In this embodiment, the comprehensive vision training system 100 in Embodiment 1 and Embodiment 2 is further improved, and a target 180 is added to ease the visual fatigue caused by reading and writing for a long time.

[0075] This embodiment is described by taking the comprehensive vision training system 100 in Embodiment 1 as an example.

[0076] A target 180 is slidably disposed on the bottom plate 110 . The target 180 may be a board with an image, an eye chart, or the like. The target 180 is driven by transmission structures such as slide rails, conveyor belts, screw nut pairs, cylinders, hydraulic cylinders, rollers, etc., and moves back and forth between the placement area where the reading material 200 is placed and the right end of the bottom plate 110 to approach or stay away from the first reflector 150. Part or all of the target 180 is at the same level as the first reflector 150 , so that its image is horizontally incident on the first...

Abstract

The invention discloses a comprehensive vision training system. The comprehensive vision training system comprises a base plate, a support part, a cover, an optical lens set, a first reflector, a second reflector and a third reflector. A patient observes images of reading materials through an emergent ray opening, so that the patient can normally read and write visual objects in a long sight distance and in a good sitting posture; the patient observes the images of the reading materials through the upper part of the cover so as to get the distance vision capacity trained; the patient observes moving objects through the emergent ray opening, therefore, asthenopia brought by long-time reading and writing of the visual objects is relieved. Based on the primary cause of myopia due to asthenopia caused by short-distance reading and writing of visual objects, the comprehensive vision training system is adopted for comprehensively preventing and improving myopia in many ways; the system is low in cost and risk, has the ability of controlling myopia development, and prevents continuous deepening of the myopia degree and recurrence of myopia.

Description

technical field [0001] The invention relates to a vision correction device. Background technique [0002] At present, the proportion of myopia population is gradually increasing, and there is a trend of younger age. In order to alleviate the problem of vision loss caused by myopia, the traditional method is optometry and glasses. However, wearing glasses can only temporarily alleviate the problem of insufficient vision, and has no ability to control the development of myopia, and even lead to the continuous deepening of myopia. [0003] A more advanced treatment for myopia is laser surgery that changes the diopter of the cornea. However, such surgery is expensive and has certain risks, which may cause sequelae after surgery. Moreover, there is also the problem of recurrence of myopia in patients after surgery. Contents of the invention [0004] In view of this, the purpose of the present invention is to provide a comprehensive vision training system, which can extend th...
