Abstract
The utility model relates to spectacles for myopia, in particular to myopia control spectacles, which comprises a spectacle frame and concave spectacle lenses. The outer side of each concave spectacle lens is provided with a prism with the same size as the concave spectacle lens, the base of each prism faces towards the middle portion of the spectacles, namely one side of each prism approaching the nose bridge of a user is thicker while the other side away from the nose bridge of the user is thinner. As pupils of the users need big conversion when using conventional concave lenses to view from a distance to close objects, eyes are easy to be fatigue and degree of myopia can be increased. After being added with the prisms, parallel light deviates towards the base after passing through the prisms, and then eye positions in excess convergence in close distance is relieved, and conversion range of pupils when people view objects from far to near is reduced, thereby achieving the purpose of protecting eyes well. Further, because the concave lenses are integrated with the prisms, the spectacle lenses are light in weight and small in volume.
Description
Technical field
The utility model relates to a kind of spectacles, especially relates to a kind of myopia control mirror.
Background technology
The glasses of conventional myopic eye generally be by a width of cloth concavees lens as eyeglass, concavees lens can only solve the needs of seeing when far away, as wear mirror and see closely, can increase to regulate the near-sighted number of degrees are further increased.In order to address this problem, the someone has designed and has a kind ofly added the method for prism with convex lens, as the patent No. is
200620084401http: //www.soopat.com/Patent/Search.rails? the utility model of Parameter.SearchWord=SQH%3a (200620084401) discloses a kind of physiotherapeutic glasses for myopia, its structure is to be made of mirror holder and eyeglass disposed thereon, and characteristics are that eyeglass is to be composited by convex lens and the inside prism of substrate.Utilize the optically focused performance of convex lens and the refractive property of prism, simultaneously by means of the melting as function and look instinct clearly of eyes, when making nearly eye operation, eyes are in the state of looking in the distance, and impel ciliary muscle to produce reciprocal relaxation force.But the form of convex lens+prism will be unfavorable for posture and body development apart from very near when seeing object, sees when far away very fuzzyly, and very burden is arranged.The patent No. is that 00229336 utility model discloses a kind of Spectacle for myopia, and its eyeglass is a kind of prismatic glasses or a kind of by the synthetic eyeglass of convex lens, concavees lens and prism; The angle of wedge A of prismatic glasses is 23 °～9 °, and prismatic glasses can be inside and outside serrate, and its drift angle A reduces step by step.Though this utility model has also been mentioned the array mode that adopts concavees lens and prism, but from its whole content, still there is a very big problem in its manufacture, its prism is mounted in the lens inboard, and the inboard of concave spectacle lens is a concave surface, so, these concavees lens and prism combine the difficulty that exists in the very big processing, in fact, from its design proposal, the concave part that its prism can only touch with it is fitted.The part that also just can only accomplish this eyeglass is used to see at a distance, part is used to see nearby.Therefore, the user is difficult to custom.
Summary of the invention
The utility model mainly is to solve existing in prior technology myopia control mirror to exist difficulty of processing big, and the technical matters of the very difficult adaptation of user etc. provides a kind of handling ease, and the control of myopia is effective, and the myopia that the user adapts to is easily controlled mirror.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals: a kind of myopia control mirror, comprise mirror holder and concave spectacle lens, the outside that it is characterized in that described concave spectacle lens is provided with a prism sizable with it, and the substrate of this prism is towards the glasses middle part.Substrate refers to prism towards glasses middle parts thicker near a side of user's bridge of the nose, thinner away from a side of user's bridge of the nose.User's pupil when using traditional concave spectacle lens from seeing at a distance to seeing near objects need be changed largely, increases easily and uses kopiopia, makes myopic degree deepen easily.After adding prism, parallel rays is by behind the prism, and the based direction deviation of light in order to alleviate closely the eye position of excessively set, makes people when seeing far and near object, and the transition amplitude of its pupil is less, to reach the effect of better protect eyes.Two because concavees lens also prism combine together, thus eyeglass in light weight, volume is little.
As preferably, described prism is a prism, and its drift angle is 9 to spend to 23 degree.The too little meeting of this angle does not have effect, and the deflection angle when too light is used in conference by prism is excessive.
As preferably, the described prism outside towards and the primary optical axis of concave spectacle lens between a downward differential seat angle is arranged.Because often the people's of reading visual angle usually is downward, thus this design proposal be the prism outside towards and the primary optical axis of concave spectacle lens between a downward differential seat angle is arranged.
As preferably, described prism has the distortion of certain radian, merges mutually to reach with concave spectacle lens.Make it reach attractive in appearance, compact effect.
The beneficial effect that brings of the present utility model is, solved existing in prior technology myopia control mirror and existed difficulty of processing big, the technical matters of the very difficult adaptation of user etc. provides a kind of handling ease, the control of myopia is effective, the myopia control mirror that the user adapts to easily.
Therefore, the utlity model has characteristics such as rational in infrastructure, easy to use.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model;
Accompanying drawing 2 is a kind of fundamental diagrams of the present utility model;
Accompanying drawing 3 is a kind of fundamental diagrams of the present utility model.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: accompanying drawing 1 is a kind of structural representation of the present utility model, and accompanying drawing 2 is a kind of fundamental diagrams of the present utility model, and accompanying drawing 3 is a kind of fundamental diagrams of the present utility model.It comprises mirror holder and concave spectacle lens 3, the prism 2 that it is the 9-23 degree that the outside of concave spectacle lens is provided with a drift angle sizable with it, prism has the distortion of certain radian, merge mutually to reach with concave spectacle lens, the substrate of this prism is towards the glasses middle part, substrate refers to prism towards glasses middle parts thicker near a side of user's bridge of the nose, thinner away from a side of user's bridge of the nose.The prism outside towards and the primary optical axis of concave spectacle lens between a downward differential seat angle is arranged.Substrate refers to prism towards glasses middle parts thicker near a side of user's bridge of the nose, thinner away from a side of user's bridge of the nose.
User's pupil 4 when using traditional concave spectacle lens from seeing at a distance to seeing near objects 1 need be changed largely, increases easily and uses kopiopia, makes myopic degree deepen easily.After adding prism, parallel rays is by behind the prism, and the based direction deviation of light in order to alleviate closely the eye position of excessively set, makes people when seeing far and near object, and the transition amplitude of its pupil is less, to reach the effect of better protect eyes.
So the handling ease of the utlity model has, the control of myopia is effective, and the user is feature such as adaptations easily, and eyeglass in light weight, volume is little, is fit to very much A nearsighted person's use.
