  The present invention provides a functional eyeglass lens for blocking ultraviolet and blue light, which comprises a mixture of the following materials: a polymerization initiator which reacts with a monomer, which is a raw material of a plastic lens whose refractive index varies depending on physical properties, and which converts the monomer into a polymer; an ultraviolet absorber for absorbing ultraviolet from a plastic lens which is mixed with the monomer to then be converted into a polymer; and a transparent material for making the plastic lens, which has been mixed with the monomer and converted into a polymer, transparent by minimizing a phenomenon in which the plastic lens appears yellow, wherein the ultraviolet absorber comprises a mixture of any one or more of UV-A, UV-B and UV-C which are benzotriazole-based ultraviolet absorbers having different molecular weights, and the transparent material is a mixture of a blue dye, showing blue color, and a red dye, showing red color, which is mixed with the monomer at a predetermined ratio.

  本发明提供了一种阻挡紫外线和蓝光的功能性眼镜片，它由以下材料混合而成：聚合引发剂，它与单体反应，单体是塑料镜片的原材料，其折射率根据物理性质而变化，它将单体转化为聚合物； 紫外线吸收剂，用于吸收塑料镜片中的紫外线，它与单体混合，然后转化为聚合物；紫外线吸收剂包括 UV-A、UV-B 和 UV-C 中任意一种或多种具有不同分子量的苯并三唑基紫外线吸收剂的混合物，而透明材料则是显示蓝色的蓝色染料和显示红色的红色染料的混合物，按预定比例与单体混合。
