Abstract

The invention relates to the technical field of spectacle lens preparation, in particular to a preparation method of a self-cleaning spectacle lens, which comprises the following steps: S1, preparinga polycarbonate base material; S2, soaking the polycarbonate base material obtained in the step S1 in deionized water for 1-3 hours; soaking for 5 to 10 minutes by using 5 to 10 percent of hydrogen peroxide; and S3, immersing the polycarbonate base material treated in the step S2 into a titanium dioxide-containing composite material dispersing agent for 5-15 seconds, and drying in vacuum to obtainthe polycarbonate composite material. The spectacle lens prepared by taking the titanium dioxide composite material as the dispersing agent has good mechanical properties, has a better absorption effect on ultraviolet light, has good antistatic capacity, reduces dust adsorption, and can be kept in a clean state for a long time.

Description

technical field [0001] The invention relates to the technical field of spectacle lens preparation, in particular to a method for preparing self-cleaning spectacle lenses. Background technique [0002] At present, spectacle lenses on the market are mainly made of glass and resin. Glass spectacle lenses are more resistant to scratches than resin lenses, but their refractive index is relatively high, and their weight is much heavier than resin lenses, and the glass material is fragile. Not durable. Resin spectacle lenses come from coniferous plants and are a polymer mixture composed of various hydrocarbon secretions. Compared with glass lenses, the material is lighter, but the surface is not wear-resistant and prone to scratches. [0003] Whether it is made of glass or resin, the surface of the lens will generate static electricity, which will cause dust, particles and other pollutants in the air to deposit on the surface of the lens. It needs to be wiped frequently during use...
