一种防蓝光树脂镜片的制造方法及产品
摘要：
本发明为一种防蓝光树脂镜片的制造方法及产品。本发明方法在热固型光学树脂单体中填充紫外线吸收剂、蓝光吸收剂制成镜片，包括步骤：1）将热固型光学树脂单体重量的600ppm~800ppm或60ppm~90ppm量的OLP黑色素粉末与极性有机溶剂、脂溶性增溶剂混合，混合重量比为OLP黑色素粉末：极性有机溶剂：脂溶性增溶剂=1：（20~50）：（0.00001~0.0002），搅拌至充分溶解，形成蓝光吸收剂；2）将紫外线吸收剂按热固型光学树脂单体重量的0.5%~2%，加入热固型光学树脂单体中进行混合，然后加入蓝光吸收剂混合，搅拌后热固成型。本发明产品在极少改变长波光透过率的情况下，改善镜片的防蓝光性能。
摘要（英）：

The invention relates to a manufacturing method of a blue light prevention resin lens, and the blue light prevention resin lens. According to the method, a lens is manufactured by filling an ultraviolet absorbent and a blue light absorbent in a thermosetting optical resin monomer. The method comprises the following steps: (1) mixing the thermosetting optical resin monomer with the weight of 600-800ppm or OLP melanin powder with the weight of 60-90ppm with polar organic solvent and fat-soluble solubilizer, wherein the weight ratio of the OLP melanin powder to the polar organic solvent to the fat-soluble solubilizer is 1:(20-50):(0.00001-0.00002), and stirring till the mixture is fully dissolved to form the blue light absorbent; (2) adding the ultraviolet absorbent with the weight being 0.5-2% that of the thermosetting optical resin monomer in the thermosetting optical resin monomer for mixing, then adding the blue light absorbent for mixing, and then stirring for thermosetting forming. Under the condition that the long-wave light transmissivity of the lens is rarely changed, the blue light prevention performance of the lens is improved.
