Embodiment Construction

[0025] Depend on figure 1 It is known that an anti-high-energy blue light invisible grid anti-glare lens is provided with an invisible mesh-shaped chrome-plated layer on the surface of the invisible grid anti-glare lens. 0.6~0.9mm.

[0026] The components of the anti-high-energy blue light invisible grid anti-glare lens are: 985-991 grams of resin monomer, 0.4-2.0 grams of resin catalyst, 1-3 grams of resin release agent, 7-12 grams of ultraviolet absorber, Anti-high energy blue light absorber 0.05-0.15g.

[0027] The resin monomers are brominated bisphenol A diacrylate and thiourethane.

[0028] The resin catalyst is dibutyltin dichloride, 1,1-di-tert-butylperoxy-3,3,5-trimethylcyclohexane and azobisisoheptanonitrile.

[0029] Described resin release agent is organic silicone oil, acidic acid ester.

[0030] The UV absorber is 2-(2-hydroxyl-5-tert-octylphenyl)benzotriazole, 2-(2-hydroxyl-3-tert-butyl-5methylphenyl)-5-chloro Benzotriazole.

[0031] The anti-high-energy b...

Abstract

The invention relates to a high-energy blue light-resistant stealth grid anti-glare lens and a manufacturing method thereof. The high-energy blue light-resistant stealth grid anti-glare lens is characterized in that the surface of a stealth grid anti-glare lens is coated with a stealth grid chrome-plated layer, the grid pores are arranged in a honeycomb way, the pore diameters are in a range of 0.4-0.6mm, the pore distance is in a range of 0.6-0.9mm, and the stealth grid chrome-plated layer comprises 985-991g of a resin monomer, 0.4-2.0g of a resin catalyst, 1-3g of a resin release agent, 7-12g of a UV absorber and 0.05-0.15g of a high-energy blue light-resistant absorber. The result of the test on the lens based on a UV spectrophotometer UV-2550 shows that the transmittance at 440nm is about 0.08%, the blocking effects are complete and the UV value is 450nm or more based on the international UV value evaluation standards.

Description

technical field [0001] The invention belongs to the technical field of lens manufacturing, and in particular relates to a method for manufacturing an invisible grid anti-glare lens. Background technique [0002] Glare refers to the visual condition that causes visual discomfort and reduces the visibility of objects due to unsuitable brightness distribution or extreme brightness contrast in space or time in the field of vision. In the field of vision, there is a light sensation that the human eye cannot adapt to, which may cause disgust, discomfort or even loss of vision. Excessively high brightness appears in a certain local place in the field of vision or excessive brightness changes occur before and after. Glare is one of the important causes of visual fatigue. The normal sight range of the human eye is from 30° to 60° below, and glare is glare if there is dazzling light within this range. [0003] Blue light is a relatively high-energy light with a wavelength between 4...
