A kind of cleaning anti-blue light spectacle lens

Abstract

The invention discloses a clean anti-blue-light spectacle lens.The clean anti-blue-light spectacle lens has the permeability increasing effect and the quite high anti-dust and antifouling effect.The clean anti-blue-light spectacle lens comprises a methacrylate substrate.The front main face and the back main face of the substrate are evaporated with films; the film on the front main face sequentially comprises a first hard coating, a first anti-scratching and anti-wearing layer, an anti-blue-light reflective film, a first anti-reflective film, a first anti-dust film and a first cleaning film from inside to outside; the film on the back main face sequentially comprises a second hard coating, a second anti-scratching and anti-wearing layer, a second anti-reflective film, a green-light permeability increasing film, a second anti-dust film and a second cleaning film from inside to outside; the first cleaning film and the second cleaning film are prepared from ethyoxyl nonafluorobutane and perfluoro butyl ethyl propyl ether in the ratio of 4:1.

Description

technical field [0001] The invention relates to an anti-blue light spectacle lens, in particular to a clean anti-blue light spectacle lens. Background technique [0002] In the prior art, research on anti-blue light glasses is in full swing, especially with the development of Internet technology, anti-radiation glasses including anti-blue light and anti-ultraviolet radiation have been widely used. Generally speaking, the visible light band is approximately the spectral range from a wavelength of 380 nanometers (nm) to a wavelength of 780 nm. The portion from about 380 nm to about 500 nm substantially corresponds to high-energy blue light. Blue light is very harmful to the human eye, especially the retina. If the human eye is exposed to blue light for a long time, it may cause serious ophthalmic diseases, such as age-related macular degeneration, and even lead to blindness. However, the 465nm to 495nm part of the above-mentioned blue light band is beneficial to health, beca...

Problems solved by technology

[0005] In the existing technology, the requirements of reducing blue light damage and increasing light transmittance are often incompatible. One loses the other, and one trades off. In order to reduce blue light damage, the light transmittance must be sacrificed as a price
