Description
Technical Field
The utility model relates to an eyeglass especially indicates a do benefit to improvement vision definition prevent blue light lens.
Background
Along with the popularization of electronic products, the time for people to watch a screen is longer and longer, and the blue light in screen luminescence can cause harm to human eyes after being irradiated for a long time due to strong penetrability of the blue light. Therefore, many blue light prevention glasses are put on the market, but most glasses aim at people with abnormal eyesight (myopia and presbyopia), and the blue light prevention function is added into common glasses. However, when people with normal vision wear ordinary flat blue-light-proof glasses, even the flat glasses can feel fatigue due to the reduction of definition because the flat glasses are not worn in daily life, and the protection of eyes becomes quite adverse.
SUMMERY OF THE UTILITY MODEL
Technical problem to be solved
An object of the utility model is to provide a do benefit to blue light lens of preventing that improves visual clarity, have high definition, prevent the characteristics of blue light, especially be fit for the normal crowd of eyesight and wear. In order to achieve the above purpose, the utility model adopts the following technical scheme:
(II) technical scheme
The utility model provides a do benefit to blue light prevention lens that improves visual clarity which characterized in that: the substrate is in planar design and made of polyurethane, the refractive index of the substrate is 1.60, a blue light absorption layer, a blue light reflection layer, a first zirconium dioxide (ZrO2) layer, a first titanium oxide (TiO2) layer, a hard coating, an anti-reflection film and a waterproof film are sequentially plated on the outer side of the substrate, and a second zirconium dioxide (ZrO2) layer, a second titanium dioxide (TiO2) layer and an anti-fog film are sequentially plated on the inner side of the substrate; the thickness of the first zirconium dioxide (ZrO2) layer and the second zirconium dioxide (ZrO2) layer is not more than 40nm, and the thickness of the first titanium oxide (TiO2) layer and the second titanium oxide (TiO2) layer is not more than 30 nm.
