Abstract

The invention discloses an optical lens capable of resisting blue light. The optical lens capable of resisting blue light comprises a base lens, wherein film systems are arranged on the external surface and the internal surface of the base lens; the film system on the external surface of the base lens sequentially comprises anti-impact reinforced film layers, uvioresistant film layers, blue light resisting film layers, optical regulating film layers and oil contamination resisting film layers from inside to outside; the plurality of blue light resisting film layers are arranged on the external surface of the base lens; the film system on the internal surface of the base lens sequentially comprises anti-impact reinforced film layers, uvioresistant film layers, blue light resisting film layers and oil contamination resisting film layers from inside to outside; the plurality of blue light resisting film layers and uvioresistant film layers are arranged on the internal surface of the base lens. The film layers are matched to finally form a white transparent film layer on the optical lens. The lens is capable of effectively filtering out more than 33% of harmful blue light and maintaining the light transmission rate at greater than 79%, making a good contribution to clarity and authenticity of the vision and effectively alleviating visual fatigue by filtering out the harmful blue light.

Description

technical field [0001] The invention relates to an anti-blue optical lens. Background technique [0002] It is already known that ultraviolet rays can cause damage to the eyes, and long-term ultraviolet exposure can cause cataracts. Similarly, blue light is high-energy visible light with a wavelength of 400-500nm. Blue light can directly penetrate the cornea, eye lens, and reach the retina. The death of sensitive cells, the retinal pigment epithelial cells have a strong absorption effect on the light radiation in the blue light area, and the absorption of blue light radiation will cause the retinal pigment epithelial cells to shrink, which is also one of the main causes of macular degeneration; The greater the cell damage, the atrophy of the retinal pigment epithelial cells will make the retinal image blurred, and the ciliary muscle will continue to adjust the blurred image, which will increase the work intensity of the ciliary muscle and cause visual fatigue. Under the ac...
