Abstract
A lens system set capable of controlling myopia comprises distant myopic spectacles and a lens set which is sleeved in front of the distant myopic spectacles. The distant myopic spectacles consist of a lens 2, a glasses frame 3 and a glasses leg 1. The lens 2 of the distant myopic spectacles is a concave lens, and the lens set consists of a convex lens 5 and a glasses frame 4. The lens 2 of the distant myopic spectacles and the lens 5 of the lens set are both resin lens adhered with a film with electromagnetic wave prevention and strong transparency. The convex lens 5 of the lens set has a degree of +1.75D. The frame 3 of the distant myopic spectacles and the frame 4 of the lens set are made of magnetic material or ferromagnetic material. The utility model has advantages that, when people look at the distant object, they can wear the distant myopic spectacles; when they read and write, they don not need to replace the distant myopic spectacles with near myopic spectacles. Instead, they can put the lens set in front of the distant myopic spectacles closely and reliably by the magnetic force between the lens set and the frame of the distant myopic spectacles to achieve the effect of near myopic spectacles.
Description
Technical field
The utility model relates to myopia and use glasses, and especially a kind of A nearsighted person of convenience is by seeing that change far away sees that the control myopia of using when near overlaps mirror.
Background technology
People see that pleasing to the eye light is parallel rays when far away, need not regulate after parallel rays is pleasing to the eye on the retina that images in normal eye just; And pleasing to the eye only divergent rays when seeing nearly reading and writing, divergent rays must just can be imaged onto on the retina through regulating after going into normal eye, and long-term adjusting can cause eyes muscular fatigue, just can excite myopia.
The A nearsighted person must optometry join mirror.Joining the mirror optometry generally is to carry out 5 meters distance, therefore get the right lensses for one's eyeglasses be suitable for seeing remote object far use mirror.
People see that near normalized distance is from being 33 centimeters.The inverse of distance is an adjusting power, is+3.00D.That is to say that people see the adjusting power that needs ten 3.00D when near, promptly see the convex lens that add ten 3.00D when near, see that eye is exactly the acyclic homologically trioial joint when near, can avoid the generation of myopia or further develop.
Cause eyes muscular fatigue for avoiding seeing when near, the A nearsighted person is closely optometry also, and mirror is closely used in preparation.Use two pairs of glasses better to alleviate to see and cause eyes muscular fatigue, control myopia progression when near.Shortcoming is far to see near continuous variation along with seeing, two pairs of eyes must be taken off continually or puts on, and is very inconvenient.
Summary of the invention
The purpose of this utility model is to be to avoid further developing of myopia to need preparation far away from mirror and near with two pairs of glasses of mirror at present A nearsighted person, far see near continuous variation according to seeing, two pairs of eyes must be taken off continually or put on, very inconvenient problem provides the control myopia of the additional again cover mirror of one pair of near-sighted glasses of a kind of preparation to overlap mirror.
Control myopia cover mirror described in the utility model comprises far away from near-sighted glasses and cover mirror.The cover mirror is linked in the front with near-sighted glasses far away.Far constitute by eyeglass, picture frame, mirror leg with near-sighted glasses.Far be loaded in the picture frame with the near-sighted glasses eyeglass.Both sides and mirror leg with the near-sighted glasses picture frame far away is hinged.Far away is concavees lens with the near-sighted glasses eyeglass.The cover mirror is made of eyeglass, picture frame.Cover mirror eyeglass is loaded in the picture frame.Cover mirror eyeglass is convex lens.
Be resin lens far with near-sighted glasses eyeglass and cover mirror eyeglass.
Far with posting anti electromagnetic wave, the strong rete of anti-reflection property on near-sighted glasses eyeglass and the cover mirror eyeglass eyeglass.
The number of degrees of cover mirror convex lens eyeglass are+1.75D.
Far the material with the near-sighted glasses picture frame is magnetic picture frame or ferromagnetic material picture frame.
The material of cover mirror picture frame is magnetic picture frame or ferromagnetic material picture frame.
Described anti electromagnetic wave, the rete that anti-reflection property is strong all can be buied by market, as Beijing Long Yuan spectacles factory.
In the use, wear the near-sighted glasses of using far away when seeing far object, need not during reading and writing to take far and use the nearly near-sighted glasses of using instead with near-sighted glasses, only the cover mirror need be put in and be close to the front with near-sighted glasses far away, borrow the cover mirror and far just the cover mirror can be pull-in on reliably the front with near-sighted glasses far away, reach a kind of nearly effect with near-sighted glasses with the magnetic force between the near-sighted glasses picture frame.

Fig. 1 is the structural drawing of the utility model control myopia cover mirror;
Fig. 2 is the structural map of near-sighted glasses in the utility model;
Fig. 3 is the structural map of cover mirror in the utility model.
Among the figure, 1 near-sighted glasses picture frame, 2 near-sighted glasses eyeglasses, 3 near-sighted glasses picture frames, 4 cover mirror picture frames, 5 cover mirror eyeglasses
Embodiment
The utility model is described in further detail below in conjunction with embodiment shown in the drawings:
As shown in Figure 1, control myopia cover mirror described in the utility model comprises far away from near-sighted glasses and cover mirror.The cover mirror is linked in the front with near-sighted glasses far away.Far constitute by eyeglass 2, picture frame 3, mirror leg 1 with near-sighted glasses.Far be loaded in the picture frame 3 with near-sighted glasses eyeglass 2.Both sides and mirror leg 1 with near-sighted glasses picture frame 3 far away is hinged.Far away is concavees lens with near-sighted glasses eyeglass 2.The cover mirror is made of eyeglass 5, picture frame 4.Cover mirror eyeglass 5 is loaded in the picture frame 4.Cover mirror eyeglass 5 is convex lens.
Far away is resin lens with near-sighted glasses eyeglass 2 and cover mirror eyeglass 5.
Far with posting anti electromagnetic wave, the strong rete of anti-reflection property on near-sighted glasses eyeglass 2 and the cover mirror eyeglass eyeglass 5.
The number of degrees of cover mirror convex lens eyeglass 5 are+1.75D.
Far the material with near-sighted glasses picture frame 3 is magnetic picture frame or ferromagnetic material picture frame.
The material of cover mirror picture frame 4 is magnetic picture frame or ferromagnetic material picture frame.
