Far-sighted write device and use method for preventing student myopia

Abstract

The invention discloses a far-sighted write device and a use method for preventing student myopia. The far-sighted write device comprises a camera, a large screen, a large mirror, a small mirror and far-sighted and short-sighted devices. The camera can shoot short-sighted write videos or contents of a computer and a mobile phone of a student in short-sighted write, the videos or contents are displayed on the large screen, an about 5m light path sight distance is connected by the large mirror and the small mirror, a mirror image similar to parallel light reaches eyeballs, short-sighted write is synchronously transformed into far-sighted write, ciliary muscles and medial rectus basically do not shrink, short-sighted write contents are finished in a rest state, environmental conditions generating myopia are eliminated, and the occurrence rate of student myopia can be reduced. The exercise capacity of the eyeballs can be trained by the far-sighted and short-sighted devices after far-sighted write or between lessons every day, and metabolism and normal development of the eyeballs are promoted. The far-sighted write device is a component of 'mutual separation automatic detection myopia prevention technology' and used for myopia prevention and aided treatment.

Description

technical field [0001] The invention belongs to the technical field of preventing and treating myopia. Background technique [0002] Students' myopia is a common disease in ophthalmology, frequently-occurring; the symptom is that the distance vision is less than 5.0; the organic lesion is mainly eye axis extension, ciliary muscle spasm; Reading and writing environment, or (and) the development of adapting to the environment due to myopia inheritance, so it can also be called school myopia; among them, ciliary muscle spasm is pseudomyopia, which is caused by the near reading and writing environment; eye axis extension is True myopia is caused by repeated episodes of false myopia; when myopia reaches ≥6.00D, it can cause genetics and complications, and even blindness; genetics plus nearsightedness can easily cause early onset, high incidence, and high degree of myopia in students, which will affect Students' physical fitness, study, life and future work will also seriously af...

Problems solved by technology

[0012] The inventor believes that in order to reduce the incidence of myopia in students, the cause of myopia must be solved, and three points must be achieved. First, the eye axis must be shortened or the corneal curvature increased; Spasm; three, and can not delay learning; however, the current mainstream optical correction and eye exercises and other technologies, methods, and measures are difficult to achieve the above three points, so the incidence of myopia cannot be reduced. The reason is that optical correction uses external force The technique of moving the focal point backwards has the side effect of promoting the development of myopia, including frame glasses, corneal contact lenses, etc. Among them, orthokeratology lenses are worn every night to compress the cornea, temporarily increasing the curvature of the cornea and reducing the diopter, and taken off during the day Under normal circumstances, the corrected distance vision can be temporarily improved when the cornea has not returned to its original state; eye exercises are a health care method based on massage of acupuncture points around the eyes in traditional Chinese medicine, and it can only feel a little comfortable
