Myopia preventing and controlling glasses integrating accommodative-convergence training and dynamic reading

Abstract

The invention relates to a pair of myopia preventing and controlling glasses integrating accommodative-convergence training and dynamic reading. The pair of glasses comprises mother lenses and assistant son lenses, and the mother lenses and the assistant son lenses in a glasses frame are connected via middle beams. The pair of glasses is characterized in that the assistant son lenses are two independent assistant son lenses which are respectively matched with vision degrees of left and right lenses of the mother lenses; a driving motor is installed on the middle beam of a mother lens frame; the driving motor drives the son lenses to rotate or overturn by taking the middle beam as the central point; and a control device supplies power to the driving motor and electrically controls the driving motor. According to the glasses provided by the invention, the glasses are used to improve the adjusting ability and sensitivity of ciliaris and alleviate visual fatigue, and meanwhile change near vision to looking in distance and convert static reading to dynamic reading so as to prevent, control and alleviate generation and development of myopia and avoid early occurrence of presbyopia. According to the pair of glasses disclosed by the invention, the defects that a pair of glasses in the prior art is just used to look nearly and is not used to look in distance in the using process, has a single reading function, cannot be used as a training tool for accommodative convergence, is just used for static reading and cannot be used for dynamic reading are overcome.

Description

technical field [0001] The invention relates to a kind of myopia prevention and control multifunctional glasses which can be used not only as a set adjustment training tool, but also can change static reading from near vision to telephoto or near distance into dynamic reading. Background technique [0002] Heavy study, a lot of reading, indulging in video games, and unrestrained surfing the Internet all require excessive adjustment and concentrated eye use at close range for a long time, which puts a heavy burden on our eyes, resulting in decreased eye adjustment function and ciliary muscle spasm. , making more and more patients with visual fatigue, myopia and presbyopia appear prematurely. [0003] One of the ways to prevent and control myopia is to see far more than near, and change the environmental factors of myopia by wearing corrective glasses. When nearsightedness, the ciliary contraction, lens thickening, and the muscle energy and refractive state of the visual ...

Problems solved by technology

But it has such disadvantages: when the mirror is used for a long time, the adjustment set function does not work, and new functional waste is generated.

At the same time, the mirror can only be used for short-distance vision. When looking at the distance, the glasses must be removed, otherwise the object image will be blurred, resulting in double vision and vision confusion, which is not convenient for daily use and habitual eye use.

[0008] 2. Combined myopia prevention glasses (Patent No. 200810040251.7): According to the needs of changes in eye sight distance, sub-lenses with convex lenses or prism lens combinations are attached to different positions of the main lens of the mother frame. The disadvantage of this technology is that there are too many sub-lenses , high cost, not conducive to storage, every time the lens is changed, it must be manually disassembled, which causes inconvenience in use and is not conducive to promotion

[0009] 3. Ophthalmic lens design for controlling myopia (Patent No. 201080006989.7): Glasses use lenses designed with wavefront data from the eye to reduce optical defocus and aberrations around the lens to control the development of myopia. This technology is only for myopia The improvement of the lens of the glasses worn by the users failed to change the environmental factors of myopia caused by the over-adjustment of the concentrated eyes at close range

But it needs to manually turn over the lens for training, which is laborious. At the same time, the lens always touches the user's glasses during the turning process, which makes the operation very inconvenient
