Film coating method capable of enabling lens to achieve wear resistance, corrosion resistance and reflection resistance

Abstract

The invention relates to a film coating method capable of enabling a lens to achieve wear resistance, corrosion resistance and reflection resistance. The film coating method comprises the following steps of: 1) cleaning and drying a substrate; and 2) performing film coating on inner and outer surfaces of the substrate separately: first film layer double-sided coating, second film layer double-sided coating, third film layer double-sided coating, fourth film layer double-sided coating and fifth film layer double-sided coating. The lens is equipped with a plurality of film layers, and has the advantages such as wear resistance, good corrosion resistance, high abrasive resistance and strong reflection resistance.

Description

technical field [0001] The invention relates to the technical field of lenses, in particular to an anti-wear, anti-corrosion and lens-increasing coating method. 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.

Problems solved by technology

[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 sports, so The degree of wear resistance of the lens is also a consideration for consumers when purchasing. Currently, the surface hardness of TAC polarized lenses on the market can only reach H, and its wear resistance is 1.5. It is easy to be scratched or broken by hard objects. , affect the user's observation effect, not only bring inconvenience to the user, but also need to be replaced frequently, increase the cost of use, and need to be improved

In addition, the existing lenses also have defects such as poor corrosion resistance, easy demoulding when exposed to seawater, and poor anti-reflection properties.
