Description

A kind of control spectacles

(1) technical field

The utility model relates to a kind of glasses, relates in particular to a kind ofly can solve eyes muscular fatigue and convergence power phenomenon simultaneously, plays the glasses of prevention and the effect of treatment myopia.

(2) background technology

At present, China pupils and students' near-sighted problem becomes increasingly conspicuous, though there are the glasses of numerous treatment myopia to occur, all fails fundamentally to address this problem, and it is former in the origin cause of formation investigation from myopia.The origin cause of formation of myopia mainly contains two kinds, the one, human eye is when seeing near objects, can cause the contraction of ciliary muscle reflectivity, see object clearly to change curvature of lens, when this reflection continued when of a specified duration, will cause the fatigue of ciliary muscle, make it and can't loosen, in the course of time will cause and to see distant objects clearly, become myopia; The convergence power that makes eyeball inside can appear in human eye when seeing near objects, this convergence power can cause the optic nerve reflection synchronously, causes eye muscle to produce tonicity and regulates, thereby make eyes be in fatigue state.Though spectacles can solve the problem of seeing that distant objects is unclear, concave lens has increased the weight of the adjusting burden of eyes when seeing near objects, causes the kopiopia aggravation; Simultaneously, when looking nearly object, eyeball will inwardly be assembled productive set power, can occur causing because of convergence power the problem of eye fatigue like this in ciliary muscle fatigue, make myopic degree deepen day by day.

In the prior art, immediate with the utility model is by the disclosed 99254419.x utility model patent of Patent Office of the People's Republic of China.This patent adopts the progressive multifocal principle design, the design of its transition region has partly solved human eye and has looked near and looking eyeglass has only a photocentre when far away, can not make sight line nature continuous transition, and the picture jumping problem of bifocals, but fail to solve when looking nearly object because the synchronous nervous problem of flesh of looking that the eyeball convergence power causes.Transferred simultaneously applicant's No. 932203670.8 Chinese utility model patent, then adopt the design proposal that in concave lens, incorporates prism, solved the convergence power phenomenon that when seeing near objects, occurs, but because eyeglass is two light, exist image-jumping phenomenon, and the sight line focus can't natural transition, make the patient that uncomfortable sensation be arranged, pattern is not attractive in appearance, the problem that is difficult to promote.That is to say in the glasses of existing treatment myopia, there be not a kind of can the solution simultaneously when closely looking thing owing to the tonus of ocular muscles problem of excessively regulating and the generation of convergence power causes, especially in the time of can not avoiding single dioptric to rescue, the generation of convergence power will cause the contradiction that tonus of ocular muscles is regulated once more.

(3) summary of the invention

The purpose of this utility model is exactly in order to solve above-mentioned the deficiencies in the prior art, a kind of tonicity adjusting and convergence power phenomenon that solves ciliary muscle simultaneously that have is provided, can effectively prevent and treat myopia, and the various harmful light of energy filtering, the control spectacles of advantages of simple structure and simple.

For achieving the above object, the utility model has adopted following technical scheme: a kind of control spectacles, and it comprises picture frame, mirror holder and eyeglass is characterized in that: eyeglass top is for looking the far field; The left and right sides, eyeglass middle and lower part is the astigmatism district; The eyeglass middle part is prism polarisation transition region, the regular linable visual corridor of being made up of the focus that changes from high to low on it; The eyeglass bottom is to have the nearly mist visor section of prism effect or claim the low degree short sightedness lens region.

The described far field of looking is the concave lens that concavees lens make.

Described astigmatism district is an astigmatic lens.

The eyeglass of described prism polarisation transition region and nearly mist visor section adopts prism technology to make prism structures, each the corresponding photocentre on simultaneously should the zone eyeglass thereupon laterally vertical direction be offset gradually.

The eyeglass base of described prism polarisation transition region and nearly mist visor section is curved to be changed, and makes this zone possess the effect of prism, each the corresponding photocentre on simultaneously should the zone eyeglass thereupon laterally vertical direction be offset gradually.

Incorporate the different material of refractive index in the eyeglass of described prism polarisation transition region and nearly mist visor section, make this zone possess the effect of prism, each the corresponding photocentre on simultaneously should the zone eyeglass thereupon laterally vertical direction be offset gradually.

On the described eyeglass plated film is arranged.

The middle and lower part of the utility model eyeglass is to see far and seeing that focus is different when near according to human eye, make the arrangement being aligned of their rules by dioptric change according to the focal variation rule, constitute visual corridor, effectively solved eyes from looking as far as looking the visual fatigue that sight line when near can not natural transition causes and the picture jumping problem of bifocals; Simultaneously, this zone has adopted the prism processes to make, become prism structures,, each photocentre is offset to eyeglass outside vertical direction because prism has refraction action to light, the light of looking when near changes its direction by refraction, make it to become directional light and enter eyes, thereby removed the convergence power of eyes, eliminated the nervous problem of eye muscle, really solved two principal elements that cause myopia, myopia has been had tangible prevention and therapeutic action.

(4) description of drawings

The utility model is described in further detail below in conjunction with accompanying drawing and embodiment.

Fig. 1 is a structural representation of the present utility model.
