Problems solved by technology

(2) After the blue light enters the fundus and is focused, the focal point does not fall on the retina, but falls between the retina and the lens, which increases the chromatic aberration distance of the light focusing in the eye, and the distance between the focal points in the eye It is the main cause of blurred vision, so the injection of blue light will exacerbate chromatic aberration and visual blurring, and then the eye muscles will be overly tense, the blood supply to the eyes will be overly tense, and the blood supply to the eyes will be strengthened, which will aggravate fatigue

Abstract

The invention relates to a blue-light-resistant resin lens of 1.60 in refractivity. The blue-light-resistant resin lens comprises a resin substrate of 1.60 in refractivity, a hardened film layer is dipcoated on the resin substrate, and a first SiO2 film layer, a ZrO2 film layer, a second SiO2 film layer, a Ti2O3 film layer, an In2O3 film layer and a third SiO2 film layer are sequentially deposited on the surface of the hardened film layer. The blue-light-resistant resin lens can filter 40-50% of blue light of 400-500nm in wavelength and can effectively filter blue light radiation, pricking and soreness of eyes can be reduced, eye dryness and eye fatigue can be reduced, and cataract and maculopathy 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...
