Abstract

The utility model discloses a kind of photochromic lens; it is combined by eyeglass base, discoloration film layer, protective film layer and strengthening layer, the discoloration liquid that discoloration film layer is produced by En Xi Photoelectric Co., Ltd. solidifies, and the refractive index for the film layer that changes colour is 1.58; light transmittance is 90% or more, with a thickness of 15 μm.The utility model structure is simple, eyeglass color change is fast, experimental results: the light transmittance of the utility model color-changing lens be 15.37-82.61%, as light color deepen the time required for color be 5 seconds, as dark color shoal the time required for color be 7 seconds, using effect is obviously improved.

Description

Photochromic lens

Technical field

The utility model relates to the technical field of eyeglass, in particular to a kind of photochromic lens.

Background technique

So-called color-changing lens are a kind of to become dark when under the light (usually ultraviolet light) for being exposed to certain specific wavelength Eyeglass, and no longer will ought be replied original light transmittance by the irradiation of this light source and become clear.Color-changing lens are distinctive because of its Property is widely used in sunglasses, optical frames, snow goggles, kinetoscope and protective glasses.But there is change in existing color-changing lens The slow defect of color, using effect are ideal not to the utmost.

Utility model content

The purpose of this utility model is to provide a kind of photochromic lens, structure is simple, it can be achieved that quick color-changing, mentions Rise using effect.

To achieve the goals above, the solution of the utility model is:

Photochromic lens are combined by eyeglass base, discoloration film layer, protective film layer and strengthening layer, discoloration film layer by The discoloration liquid of En Xi Photoelectric Co., Ltd. production solidifies, and the refractive index for the film layer that changes colour is 1.58, and light transmittance is 90% or more, With a thickness of 15 μm.

The protective film layer with a thickness of 3 μm, the effect of protective film is to increase lens surface hardness, anti-scratch.

The hardness of the strengthening layer is 4H, with a thickness of 3 μm.

After adopting the above scheme, the utility model structure is simple, selects specific discoloration liquid to solidify, refractive index is 1.58, light transmittance is 90% or more, and with a thickness of 15 μm, so that eyeglass color change is fast, experimental results: the utility model becomes The light transmittance of Look mirror piece be 15.37-82.61%, as light color deepen the time required for color be 5 seconds, shoaled needed for color as dark color The time wanted is 7 seconds, and using effect is obviously improved.

The utility model is described in further detail below in conjunction with drawings and the specific embodiments.

Detailed description of the invention

Fig. 1 is the light transmittance test chart of the utility model；

Fig. 2 is the structural schematic diagram of the utility model；

Fig. 3 is the partial enlarged view of Fig. 2.

Label declaration

Eyeglass base 1, change colour film layer 2, protective film layer 3, strengthening layer 4.

Specific embodiment

As shown in Figures 2 and 3, the photochromic lens that the utility model discloses by eyeglass base 1, discoloration film layer 2, are protected Cuticular layer 3 and strengthening layer 4 are combined.

Eyeglass 1 is made of glass or plastic material.

The discoloration liquid that discoloration film layer 2 is produced by En Xi Photoelectric Co., Ltd. solidifies, and the refractive index of discoloration film layer 2 is 1.58, light transmittance is 90% or more, with a thickness of 15 μm.

Protective film layer 3 with a thickness of 3 μm, the effect of protective film layer 3 is to increase lens surface hardness, anti-scratch.

The hardness of strengthening layer 4 is 4H, with a thickness of 3 μm.

The utility model structure is simple, and eyeglass color change is fast, experimental results: as shown in Figure 1, the utility model becomes The light transmittance of Look mirror piece be 15.37-82.61%, as light color deepen the time required for color be 5 seconds, shoaled needed for color as dark color The time wanted is 7 seconds, and using effect is obviously improved.
