Abstract

Provided is a blue-light proofing resin lens manufacturing method including the following steps, by weight percent, of preparing a silica resin lens hardening liquid containing blue light wavelength conversion particles, and dip-coating and mixing the hardening liquid containing the blue light wavelength conversion particles. According to the invention, the method can change the blue light having a wave length in the range of 400-480nm and being harmful to human eyes into near infrared light having a wave length in the range of 850-950nm, on the premise of guaranteeing the light transmittance of the lens, the original blue-light proofing capability of the lens is significantly improved, and the blue light attenuation rate reaches to more than 20%, so that the blue light transmittance is selectively attenuated while the integral high light transmittance of the lens is considered, and the window transfer transmittance adjustment of blue light frequencies is realized. The blue-light proofing resin lens manufacturing method has the characteristics of novel creativity, special technology, simple process, high practicality, and selective adjustment of blue light attenuation rate.

Description

technical field

[0001] The invention relates to the technical field of manufacturing and application of anti-blue light resin lenses, in particular to a method for manufacturing an anti-blue light resin lens coated with blue light wavelength conversion particles and a hard film layer. Background technique

[0002] Scientific research has proved that blue light with a wavelength of 400-480nm is potentially harmful to people's eyes due to its short wavelength and high energy. Blue light can directly penetrate the lens and reach the fundus and retina, causing eye discomfort, visual fatigue, and retinal pigmentation. The decline of epithelial cells and long-term exposure to high-intensity blue light will cause macular degeneration, resulting in blurred vision and decreased vision. Since the damage caused by blue light to people's eyes has been confirmed and confirmed by medicine, it has gradually caused medical problems. The world and the glasses manufacturing industry have atta...
