Abstract

The invention relates to a blue light prevention optical lens which comprises a substrate, and a front composite blue light prevention film layer and a reverse composite blue light prevention film layer which are positioned on the front and reverse sides of the substrate, wherein the front composite blue light prevention film layer sequentially comprises a first silicon monoxide layer, an antimony oxide layer, a first silicon dioxide layer, a first stannic oxide / cerium dioxide / palladium / platinum compound layer, a second silicon dioxide layer and a first potassium fluoride layer from the interior to exterior; and the reverse composite blue light prevention film layer sequentially comprises a second silicon monoxide layer, a second stannic oxide / cerium dioxide / palladium / platinum compound layer, a third silicon dioxide layer and a second potassium fluoride layer. According to the optical lens disclosed by the invention, the transmittance of short-wave harmful blue light is reduced, visual fatigue is effectively relieved, the retina is protected, high transmittance of beneficial blue light is guaranteed, and the visual clarity and authenticity can be improved.

Description

technical field [0001] The invention belongs to the field of optical lenses, and in particular relates to an anti-blue optical lens. Background technique [0002] Blue light is the wavelength of visible light closest to ultraviolet light, its wavelength range is between 400-500nm, and it appears blue in the sense of human eyes. With the rapid development of society, people's lives are filled with various electronic products such as computers, mobile phones, and TVs. People are also increasingly dependent on electronic products, and the screens of electronic products emit a large amount of irregular short-wave blue light. It will directly penetrate the cornea and reach the retina, causing the retina to produce free radicals, which lead to the decline of retinal pigment epithelial cells, and then make the photosensitive cells lack nutrients, causing visual impairment, macular degeneration, squeezing and shrinking the lens, causing myopia and even the macular area lesion.
