Visual aid for vision correction and rehabilitation

Abstract

The invention discloses a visual aid for vision correction and rehabilitation. The visual aid comprises a body and a vision rehabilitation assembly connected to the body. In each embodiment of the invention, the visual aid can be returning contact lenses, returning eyeglasses, backtracking contact lenses or backtracking eyeglasses, can be used for changing the corneal radian of a corrected person and adjusting the eye axis length of the corrected person during blinking, and has the effects of lightening vision adjusting burden, starting visual feedback rehabilitation of a vision mechanism and fulfilling the aim of vision returning treatment.

Description

technical field [0001] The invention relates to a visual aid, in particular to a visual aid for vision correction and rehabilitation. Background technique [0002] The most troublesome thing about myopia is that you have to wear glasses all your life. However, it was originally just a lack of long-distance vision and sluggishness, but this result was caused by the misuse of technology. Regardless of the improvement of the material and comfort of glasses or contact lenses, or corneal reshaping in new corneal therapy, corneal refraction in laser myopia and corneal ring implant surgery instead of lens refraction, all of them only pay attention to the function of refraction correction and ignore it. The function of visual rehabilitation causes myopia to lose the chance of rehabilitation due to their complete dependence on refractive correction. Vision correction in these ways has been disappointing in terms of vision recovery, and has limited range of effectiveness by acting on...

Furthermore, if Figure 1F The vision recovery and correction method of the alternative therapy shown is mainly aimed at relaxing the eye muscles, and most of them use the relaxation and adjustment of the conscious eye muscle training to restore the vision, or use drugs to relax the ciliary muscle. Or use physical or traditional Chinese medicine to relax eye muscles 232, massage, electrotherapy, and acupuncture to restore vision, all of which are low-level visual feedback correction methods for vision restoration and correction. Because of the limited improvement effect of vision restoration, they cannot be widely used

[0004] In view of the above, although the existing refractive glasses can correct the focusing position of the light and have a clear image without adjusting the hyperopia function, the long-term dependence on the hyperopia function degrades, which will cause the loss of recovery opportunities, and even the degree will become deeper and deeper. ; In addition, laser surgery has risks and sequelae such as aberrations, or orthokeratology has the risk of ulcer infection, and corneal ring implant surgery also has the risk of sequelae, and the corneal curvature improved by the three are all Corneal refractive correction alone does not have the rehabilitation function at the same time; eye muscle training such as drug and physical eye muscle relaxation and vision recovery is low-level visual feedback consciousness regulation, subjective feeling, or limited recovery; Therefore, the existing visual recovery methods and devices cannot simultaneously correct and rehabilitate functions, nor can they naturally and safely activate high-level visual mechanisms, and can reorganize brain plasticity adjustments related to visual and learning impairment rehabilitation treatment
