Abstract

The invention relates to an anti-blue-ray resin lens with the refraction index of 1.56. The anti-blue-ray resin lens with the refraction index of 1.56 comprises a resin substrate with the refraction index of 1.56; the resin substrate is dip-coated with a hardened film; a first SiO2 film, a ZrO2 film, a second SiO2 film, a Ti2O3 film, an In2O3 film and a third SiO2 film are deposited on the surface of the hardened film in sequence. According to the resin lens disclosed by the invention, the effect of filtering blue rays with the wavelength of 400 to 500 nm can reach 40 to 50 percent; blue ray radiation can be filtered effectively; sharp pain, soreness and swelling of eyes can be reduced; eye dryness and eye fatigue can be reduced; cataract and macular degeneration can be prevented.

Description

technical field [0001] The invention relates to the technical field of optical lenses, more specifically, the invention relates to a method for preparing and coating a high-refractive index resin lens, and the prepared resin lens has excellent anti-blue light performance. Background technique [0002] The damage of ultraviolet rays to the eyes and the body is known to the world, and a variety of anti-ultraviolet spectacle lenses have also been developed in the prior art and have been widely used. In comparison, blue light damage has only been known to the world in recent years. According to data from the Ophthalmology Branch of the Chinese Medical Association, among the 420 million Internet users in China, 63.5% of them suffer from vision loss, cataracts, and blindness due to blue light radiation. The World Health Organization (WHO) announced that from 2006 to 2008, more than 30,000 people around the world were blinded by blue light radiation every year. [0003] Blue ligh...
