Embodiment 1
[0032] The high-efficiency blue light suppression lens in this embodiment includes a substrate and a coating layer. The material of the substrate includes CR-39 material and an ultraviolet absorber, and the ultraviolet absorber used is the composition of ultraviolet absorber UV-49 and ultraviolet absorber UV-81. The mixture, the ratio of UV absorber UV-49 and UV absorber UV81 is 10:1. The material of the substrate also contains 1.98% catechol, and the catechol is melanin; a dye is permeated between tissues inside the substrate, and the dye is Blue Blocker dye. The coating layer is SiO from the inside to the outside 2 film layer, ZrO 2 Coating, SiO 2 film layer, ZrO 2 film, ITO film, SiO 2 The corresponding film thicknesses of the film layer and User film layer are 175.8nm, 21.8nm, 28.6nm, 63.2nm, 8nm, 100nm and 2nm respectively. The coating layer enhances the light transmittance of the band greater than 500nm, and suppresses the light transmittance of less than 500nm. Th...
Embodiment 2
[0043] The high-efficiency blue light suppression lens in this embodiment includes a substrate and a coating layer. The material of the substrate includes CR-39 material and a UV absorber, and the UV absorber used is a mixture of UV-49 and Ciba UV81. UV-49 and The ratio of Ciba UV81 is 10:1. The material of the substrate also contains 0.5% catechol, and the catechol is melanin; a dye is permeated between tissues inside the substrate, and the dye is Blue Blocker dye. The coating layer is SiO from the inside to the outside 2 film layer, ZrO 2 Coating, SiO 2 film layer, ZrO 2 film, ITO film, SiO 2 The corresponding film thicknesses of the film layer and User film layer are 175.8nm, 21.8nm, 28.6nm, 63.2nm, 8nm, 100nm and 2nm respectively. The coating layer enhances the light transmittance of the band greater than 500nm, and suppresses the light transmittance of less than 500nm. The ultraviolet and visible light transmission spectrum of the lens is shown in figure 2 .
