Abstract

The utility model discloses a blue light-resistant coated eyeglass. The surface of the eyeglass is coated by 16 layers of films by using the vacuum in an evaporated manner. A first layer is a SiO2 film, a second layer is a Ti3O5 film, and a third layer is a SiO2 film. The first layer, the second layer, and the third layer can form a circulation, and the circulations can be overlapped till a fifth layer, and in addition, a sixth layer is a waterproof medicine film. The blue light-resistant coated eyeglass is advantageous in that the high light transmission eyeglass can be produced by adopting the coating permeability improvement design and the film layer design, and the structure can absorb the high-energy blue lights and the ultraviolet rays effectively, and therefore the damage on human eyes can be greatly reduced; the color of the eyeglass can remain real, the light transmission performance can be high, the electromagnetic radiation can be effectively shielded, and therefore the optimal blue light filterability and the optimal light transmission rate can be achieved, and therefore the blue light filtration can reach the optimal performance. The eyeglass having the structure has advantages of excellent anti-pressure capability, excellent anti-scratch capability, and high temperature resistance performance.

Description

A kind of anti-blue light plated film lens

Technical field

The utility model relates to the technical field of glasses, special relevant with the structure of anti-blue light plated film lens.

Background technology

Blue light is the high-energy visible ray that wavelength is 380～500nm.Blue light harm retina, can cause macula area hemorrhage, and macular diseases has surpassed the cataract in the past ranked the first.Therefore, develop anti-blue light eyeglass imperative.

Current, anti-blue light eyeglass is to adopt to add toner or staining method on the market, its transmittance is reduced to reach anti-blue light function, but this way can cause the eyeglass transmittance low, be unsuitable for indoor use, for this reason, the inventor is studied specially, develop a kind of anti-blue light eyeglass of high transmission rate, this case produces thus.

The utility model content

The purpose of this utility model is to provide a kind of anti-blue light plated film lens, to obtain best Filtering out blue rate and best transmittance, makes eyeglass filter blue light and reaches best.

To achieve these goals, the technical solution of the utility model is as follows:

A kind of anti-blue light plated film lens, utilize vacuum evaporation 16 tunic layers on the surface of eyeglass, wherein ground floor is SiO ₂rete, the second layer is Ti ₃o ₅rete, the 3rd layer is SiO ₂rete, ground floor, the second layer and the 3rd layer are as a circulation, and so circulation is superimposed to the 15 layer, and the 16 layer is the waterproof medicine film layer.

The SiO of described ground floor ₂thicknesses of layers is 257～266nm, the Ti of the second layer ₃o ₅thicknesses of layers is 743.5～752nm, the SiO of the 3rd layer ₂thicknesses of layers is 510～531nm, and the waterproof medicine film layer thickness of the 16 layer is 0.7～0.9nm.

The concrete material of described waterproof medicine film layer is fluoride.

After adopting such scheme, the utility model utilizes Film Coating Antireflection and Mo Ceng Let Meter to make the high transmission rate eyeglass, this structure has absorbed high-octane blue light and ultraviolet ray effectively, greatly reduce the injury to human eye, eyeglass color and luster fidelity has high light transmittance simultaneously, electromagnetic radiation shielding effectively, thus best Filtering out blue rate and best transmittance obtained, make eyeglass filter blue light and reach best.In addition, the eyeglass that has this structure has excellent anti-pressure ability, anti-scratch ability and the performance such as high temperature resistant.

Below in conjunction with drawings and the specific embodiments, the utility model is described in further details.

The accompanying drawing explanation

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

Fig. 2 is structure enlarged drawing of the present utility model.

Label declaration

Eyeglass 1, ground floor 2,3, the three layers 4, the 16 layers 5 of the second layers.

Embodiment

As depicted in figs. 1 and 2, be a kind of anti-blue light plated film lens that the utility model discloses, utilize vacuum evaporation 16 tunic layers on the surface of eyeglass 1, wherein ground floor 2 is SiO ₂rete, the second layer 3 is Ti ₃o ₅rete, the 3rd layer 4 is SiO ₂rete, ground floor 2, the second layer 3 and the 3rd layer 4, as a circulation, so circulate 5 times, are superimposed to the 15 layer, and the 16 layer 5 is waterproof medicine film layers.

Wherein, optimal design of the present utility model is: the SiO of ground floor 2 ₂thicknesses of layers is 257～266nm(nanometer), the Ti of the second layer 3 ₃o ₅thicknesses of layers is 743.5～752nm, the SiO of the 3rd layer 4 ₂thicknesses of layers is 510～531nm, and the waterproof medicine film layer thickness of the 16 layer 5 is 0.7～0.9nm.The concrete material of waterproof medicine film layer is fluoride.

The utility model eyeglass 1 has high transmission rate (80%) usually, after utilizing Film Coating Antireflection and Mo Ceng Let Meter, the utility model can be realized anti-blue light 95% left and right at 450nm wave amplitude place, residual 5% left and right blue light only, on average can anti-blue light more than 90%, only residual 10% following blue light at 380～500nm wave amplitude place.

These are only specific embodiment of the utility model, is not the restriction to protection domain of the present utility model.All equivalent variations of doing according to the mentality of designing of this case, all fall into the protection domain of this case.
