Embodiment 1

[0026] 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 film, 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 u...

Embodiment 2

[0037]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 film, 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 .

Abstract

The invention relates to a method of an efficient blu-ray inhibition lens. The method comprises two steps: preparing lens substrate and dyeing. The prepared lens has the visible light transmittance kept above 65 percent, has the 380-500nm short-wave visible light transmittance smaller than 10 percent (that is, most blu-ray is filtered), and has the 280-380nm short-wave visible light transmittance of almost zero (that is, barely violet ray and ultraviolet light can penetrate), the light transmittance is moderate, and the efficient blu-ray inhibition lens is truly suitable for being worn outdoors and indoors and particularly suitable for being worn by the aged. Under the premise of ensuring the visual effect, strong light of a high-brightness display, particularly HEV (Harm Energy Visible) light mainly consisting of blu-rays, is effectively shielded to reduce injury on people, and the incidence of both glaucoma and macular degeneration is reduced.

Description

technical field [0001] The invention relates to a preparation method of a lens, in particular to a preparation method of a high-efficiency blue light suppression lens. Background technique [0002] According to the survey of "Macwelt", the radiation of LCD screen is much smaller than that of ordinary screen, but if the brightness is too high, it is more likely to damage our eyes and cause symptoms such as fatigue, soreness, fever and even pain. The researchers pointed out that when the brightness of the display reaches [AD] 100cd per square meter, it will already have a certain impact on the eyes. However, the luminous intensity of the LCD screens they tested all exceeded 300cd per square meter, and some even reached 400cd-500cd. [0003] According to research by professors Die Monocrom-Lichtdome, A. Wunsch, Sensora Light Modulation and R.H.W. Funk, our eyes can become dysfunctional when continuously exposed to "inappropriate light", especially light from LED lights, comput...
