Anti-blue-ray ultraviolet lens

Abstract

The invention discloses an anti-blue-ray ultraviolet lens. The anti-blue-ray ultraviolet lens comprises a base layer, the base layer comprises a substrate and coating layers; the coating layers are adhered on outer surfaces of an upper end and a lower end of the substrate; an ultraviolet absorbing film is adhered on the outer surface of the top end of the base layer, an Ag film is adhered on the outer surface of the top end of the ultraviolet absorbing film, and a PE film layer is adhered on the outer surface of the top end of the Ag film. The anti-blue-ray ultraviolet lens disclosed by the invention can realize the protection capacity of each protective film and better improve the transmittance of the light way by strictly controlling the thickness of each protective film, and the problemthat the existing lens is thick in thickness and low in transmittance can be well solved; secondly; various protective films are supplemented with each other, the conflict is avoided, the protectivefilms can be mutually promoted, and the entire comprehensive use effect is improved; and by mounting the Ag film in the lens, the bacteria surface breeding on the lens can be prevented.

Description

technical field [0001] The invention relates to the field of optical lenses, in particular to an anti-blue light ultraviolet lens. Background technique [0002] Lens is an optical lens that uses light refraction. With the continuous progress of society, the scope of use of lenses is becoming wider and wider. It is often used for astronomical observation, medical testing and vision adjustment. At the same time, there are more and more types of lenses. According to the material, it can be divided into glass lens, resin lens and space lens; [0003] The existing anti-blue light ultraviolet lens has certain disadvantages when used, and the thickness of each protective film cannot be accurately controlled. The thickness of the protective film is uneven. When the thickness is thin, the protective effect is low and cannot play its due role well. Therefore, we propose an anti-blue light ultraviolet lens. Contents of the invention [0004] The main purpose of the present inventio...

Problems solved by technology

[0003] The existing anti-blue light ultraviolet lens has certain disadvantages when used, and the thickness of each protective film cannot be accurately controlled. The thickness of the protective film is uneven. When the pass rate is thinner, the protective effect is low, and it cannot play its due role well. Therefore, we propose a blue-ray anti-ultraviolet lens
