Anti-reflection and wear-proof lens capable of filtering blue light and preparation method of anti-reflection and wear-proof lens

Abstract

The invention relates to an anti-reflection and wear-proof lens capable of filtering blue light and a preparation method of the anti-reflection and wear-proof lens. The lens comprises a substrate, wherein first film layers, second film layers, third film layers, fourth film layers, fifth film layers, sixth film layers, seventh film layers, eighth film layers and ninth film layers are symmetrically and sequentially arranged on the inner surface and the outer surface of the substrate from inside to outside; the first film layers, the third film layers and the fifth film layers are all trititanium pentoxide layers with the thickness being 10-100 nm; the second film layers, the fourth film layers and the sixth film layers are all silicon dioxide layers with the thickness being 50-100 nm; the seventh film layers are metal layers with the thickness being 5-20 nm; the eighth film layers are high-hardness layers with the thickness being 10-50 nm; the ninth film layers are acrylic acid layers with the thickness being 5-15 nm. The preparation method comprises steps as follows: 1), the substrate is cleaned; 2), the inner surface and the outer surface of the substrate are plated with films respectively. The lens can filter harmful blue light and dazzle light, and the wear resistance and the antireflection property can be improved.

Description

technical field [0001] The invention relates to the technical field of lenses, in particular to a blue light filtering anti-reflection wear-resistant lens and a preparation method thereof. Background technique [0002] With the continuous improvement of people's culture and living standards and the development of vision care work, glasses, as a simple optical device made to correct vision or protect eyes, have played an important role in people's daily life. Spectacles are usually composed of lenses and frames. From the function of lenses, it has the functions of adjusting the amount of light entering the eyes, increasing vision, protecting eye safety and clinically treating eye diseases. [0003] At present, there are many kinds of lenses, such as the common TAC polarized lens, which can block harmful light 100%, so it is very popular among consumers, especially suitable for outdoor sports. However, the lens will inevitably be scratched during exercise, so The degree of we...

[0005] In addition, in the cold winter, when people wear glasses to enter the room from the outside, a large number of water droplets will condense on the surface of the glasses, which will affect the light transmittance of the glasses and reduce people's sight, which will not only bring great inconvenience to life, but even cause danger.
