Problems solved by technology

[0003] At present, the concept of VR is also introduced in the market for refractive training, but the real point of gaze does not change the distance shown in the VR screen, but the size changes, and the focus of gaze does not really change, and it cannot drive the contraction of the ciliary muscle. -Effect of comfort regulation
[0004] Eye massage is to relieve eye fatigue and improve refractive status by stimulating the acupoints of the eyes according to the meridian theory of traditional Chinese medicine. use, and the massage effect alone is not very satisfactory

Embodiment 1

[0018] The present invention provides a VR-based refractive training device, which is suitable for people who are mainly myopic and may have mild amblyopia; the correction process is as follows: the patient sits directly in front of the training device, the eyes are attached to the silicone layer, and the elastic band can be adjusted to fix it On the head, the eyes are facing the window respectively, and the eyes are closed. Through the control of the circuit board, massage the acupoints of the eyes first, and at the same time, use the silicone layer hot compress that fits the eyes. After 3 minutes, the massage program is completed, eyes are opened, and the user starts the VR game. The game program will judge whether the user can see the game screen clearly according to the user's feedback in the game. Once it is judged that it can see clearly, it will immediately turn the double-sided disc under the control of the circuit board to switch the additional lens, and it will switc...

Embodiment 2

[0020] The invention provides a VR-based refractive training device, which is suitable for people who mainly have amblyopia, but may have myopia, hyperopia and astigmatism; the correction process is as follows: insert a black light-shielding film on the empty disc of the disc. The patient sits directly in front of the training equipment, the eyes are attached to the silicone layer, the adjustable elastic band is fixed on the head, the eyes are facing the window respectively, and the eyes are closed. Through the control of the circuit board, massage the acupoints of the eyes first, and at the same time, use the silicone layer hot compress that fits the eyes. After 3 minutes, the massage program is completed, and the eyes are opened. Under the control of the circuit board, the shading sheet is fixed on the window area of ​​the non-amblyopic eye and does not rotate anymore. The user watches VR with the amblyopic eye. The side disc for the amblyopic eye can only switch between +1....

Embodiment 3

[0022] The present invention provides a VR-based refractive training device, which is suitable for people with poor fusion function, lack of stereo vision, amblyopia, myopia, hyperopia and astigmatism; , One green and two lenses. The patient sits directly in front of the training equipment, the eyes are attached to the silicone layer, the adjustable elastic band is fixed on the head, the eyes are facing the window respectively, and the eyes are closed. Through the control of the circuit board, massage the acupoints of the eyes first, and at the same time, use the silicone layer hot compress that fits the eyes. After 3 minutes, the massage program is completed, eyes are opened, and the user starts the VR game. Under the control of the circuit board, the disc is only switched between the red lens and the green lens. After the user gets the fusion effect through the VR game content, he will give feedback, switch immediately, and switch again after seeing clearly again, and so on...

Abstract

The invention relates to refractive training equipment based on VR. The equipment is characterized by comprising an outer cover, a circuit board, a display screen, lenses, lens holding discs, additional lenses, electric acupoint massagers, a silica gel layer and an adjustable elastic cord, wherein one end of the outer cover is open, and the open end is fixedly connected to the silica gel layer; the circuit board, display screen, lenses, lens holding discs, additional lenses and electric acupoint massagers are wall wrapped by the outer cover; the adjustable elastic cord is connected to the outer cover; the additional lenses are fixed to the rotational lens holding discs on two sides, and thus the purpose of changing the refractive situations of eyes is achieved by changing the additional lenses; heating films and the electric acupoint massagers are arranged in the silica gel layer, and two windows are formed in the silica gel layer at an interval. By using the refractive training equipment based on VR, ciliaris, extraocular muscles and acupoints and main and collateral channels of the eyes can be comprehensively trained, and thus the effects of preventing and relieving myopia, and correcting strabismus and amblyopia are achieved.

Description

technical field [0001] The invention relates to the technical field of refractive error correction, in particular to a VR-based refractive training device. Background technique [0002] There are nearly 400 million people with myopia in my country, of which about 270 million are young children, and there is an increasing trend year by year, which has a serious impact on physical and mental health. Moreover, if myopia is allowed to deepen, when it develops into pathological myopia, it may cause irreversible damage to visual function. Therefore, the prevention and control of myopia in adolescents has attracted more and more attention from the whole people. In addition, there are a large number of strabismus, amblyopia, hyperopia and astigmatism, which have a great impact on visual function. The main cause of myopia in children at this stage is to use the eyes at close range for a long time. This unhealthy state of eye use will lead to continuous contraction of the ciliary m...
