Abstract

The utility model provides a degree adjustable glass, which comprises an outer layer which is made of transparent materials, an inner layer which is made of elastic transparent materials, and a sandwich layer which is formed between the inner and the outer layers and is injected with a transparent liquid, wherein, the outer layer and the inner layer are sealed at the peripheries, and are respectively provided with a fine hole. The utility model is characterized in that the degree of the glass can be adjusted by that the inner part of the sandwich layer is injected the transparent liquid to adapt the requirements for different degrees, and therefore, the service life of the glass can be extended. The utility model is especially suitable for teenagers.

Description

Can adjust the lens of the number of degrees

The utility model relates to lens, refers to a kind of concave lens or hyperopic lens that has certain number of degrees especially.

At present, commercially available concave lens or hyperopic lens, generally all be the number of degrees according to the human eye needs, selecting the different lens blank of thickness to grind forms, the shortcoming of doing like this is: in case make, the malleable number of degrees not more can not be at any time change according to the eyesight of human eye, at any time adjust the number of degrees, to adapt to different needs.Especially teenager, because the singularity in growth period, their variation of eyesight is very fast, the cycle is shorter, if adopt above-mentioned traditional eyeglass will bring financial burden.

Therefore, the purpose of this utility model is to propose a kind of lens of adjusting the number of degrees.

The purpose of this utility model is achieved in that it comprises the skin that transparent material is made, the internal layer that elastic apparent material is made, formed between the inside and outside layer, as can to inject transparency liquid interlayer; Described skin and internal layer seal at periphery, and are provided with tiny filling orifice.

Described outer field transparent material is glass or resin.

The elastic apparent material of described internal layer is plastics or film.

The transparency liquid that injects in the described interlayer is a water.

When using this eyeglass, adopt a tiny catheter, insert in the described filling orifice, inject transparency liquids such as water in interlayer, along with the injection of liquid, the internal layer that resilient material is made produces deformation, and liquid injects and is for a long time to outer gibbosity; Inject manyly more, the cambered outwards degree of internal layer is big more, and the number of degrees are also dark more, otherwise then shallow more; If when oppositely vacuumizing, then internal layer is inside concavity.

The utility model has the advantages that: simple in structure, easy to use, can adjust the number of degrees voluntarily at any time according to the eyesight variation of human eye, to meet the needs of, especially be fit to the teenager, the lens life cycle is prolonged.

Below in conjunction with drawings and Examples, the utility model is described in further detail:

Fig. 1 is the front view that can adjust the lens of the number of degrees;

Fig. 2 is the A-A cut-open view among Fig. 1;

Fig. 3 is the situation that eyeglass is convex lens among Fig. 2;

Fig. 4 is the situation that eyeglass is concave mirror among Fig. 2.

See figures.1.and.2, interlayer 3 formed, that can inject transparency liquid is formed between internal layer 2 that the skin 1 that the internal layer 2 that the skin 1 that lens of the present utility model is made by transparent material, elastic apparent material are made, transparent material are made, elastic apparent material are made and the inside and outside layer 2,1, skin 1 seals at periphery with internal layer 2, and leaves tiny filling orifice 4.

Outer 1 transparent material that adopts can be glass or resin, is ocular lens material commonly used at present.

The elastic apparent material that internal layer 2 adopts can be plastics or film.

But the transparency liquid water that injects in the interlayer 3 also can be other liquid.

Fig. 3 is outside protruding situation after the utility model lens injection water is shown, and is convex lens this moment; Water injects more after a little while, and degree of convexity is little, and the convex lens number of degrees are more shallow; Water injects more for a long time, and degree of convexity is big, and the convex lens number of degrees are darker.

Fig. 4 is the situation of caving inward after the utility model lens extraction water is shown, and is concave mirror this moment.

Claims
