Abstract
The utility model relates to a pair of myopia preventing glasses. The pair of glasses comprises a glasses frame and lenses matched with the glasses frame. The pair of glasses is characterized in that each lens is formed by compounding a convex lens and a prism. Light rays are refracted when passing through the prism, so that the direction of propagation of light can be changed to ensure that ocular axes are dispersed, the stress of medial rectus to eyeballs is removed, and eye fatigue is eliminated. The convex lenses are capable of focusing light to relieve ciliaris in eyes, so that myopia is fundamentally removed, and a good myopia prevention function is realized.
Description
Technical field
The utility model relates to a kind of glasses, especially relates to a kind of related preventive mirror.
Background technology
Society, mankind's myopiaization tendency is day by day serious, and myopia has been brought without infinite worry to the people.The age of knowledge explosion, student every day is in the study of overload, and computer, TV universal makes eyes see that near chance is more and more, and the time is also more and more longer; It is that a kind of neural reflex is movable that eyes are regulated eyesight, in read-write, the brain visual centre is accepted to stimulate and excited always, and cell electrophysiology proves, certain neurocyte is because of long-term irriate excitement, in the course of time, always there be excited constantly the biography to make it always be in contraction state to ciliary muscle, see also not allow when far away and loosen, occur seeing closely clear, see far fuzzy, thereby cause myopia generation.And existing glasses can only be used for correcting defects of vision basically, do not have the effect of related preventive, and result of use is relatively poor.
Summary of the invention
The related preventive mirror that the utility model provides a kind of eyeglass to be composited by convex lens and prism; Solve the technical matters of the effect that does not have related preventive that exists in prior art.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals: a kind of related preventive mirror, comprise mirror holder and associated eyeglass, and it is characterized in that: described eyeglass is composited by convex lens and prism.Light produces refraction by prism, can change the direction of propagation of light, and axis oculi is scattered, and removes internal rectus muscle to the compressing of eyeball, anti-eye strain; Convex lens can be light focusing, the intraocular ciliary muscle of can loosening, thus fundamentally eliminate near-sighted generation, myopia is played prevention effect preferably.
As preferably, the outside of described convex lens also is compounded with layer protecting film.Diaphragm is compounded in the outside of convex lens can with harmful light line absorptions such as ultraviolet ray, infrared ray, low frequency radiations, eliminate the near-sighted factor that causes because of the light pollution.
As preferably, described convex lens have+1.25 ± 0.25DS.
As preferably, described prism has 2.50 ± 0.50 Δs.
Therefore, the utility model has following characteristics compared to existing technology: 1. simple in structure, reasonable in design; 2. eyeglass is composited by convex lens and prism, and light produces refraction by prism, can change the direction of propagation of light, and the limit axle is scattered, and removes internal rectus muscle to the compressing of eyeball, anti-eye strain; Convex lens can be light focusing, the intraocular ciliary muscle of can loosening, thus fundamentally eliminate near-sighted generation, myopia is played prevention effect preferably
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model;
Accompanying drawing 2 is cut-open views of eyeglass.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1: see Fig. 1, Fig. 2, a kind of related preventive mirror comprises mirror holder 1 and associated eyeglass 2, and eyeglass 2 is composited by convex lens 21 and prism 22.Convex lens have+1.25 ± 0.25DS.Prism 22 has 2.50 ± 0.50 Δs.Light produces refraction by prism, can change the direction of propagation of light, and axis oculi is scattered, and removes internal rectus muscle to the compressing of eyeball, anti-eye strain; Convex lens can be light focusing, the intraocular ciliary muscle of can loosening, thus fundamentally eliminate near-sighted generation, myopia is played prevention effect preferably.
The outside at convex lens 21 also is compounded with layer protecting film 23.Diaphragm is compounded in the outside of convex lens can with harmful light line absorptions such as ultraviolet ray, infrared ray, low frequency radiations, eliminate the near-sighted factor that causes because of the light pollution.
