PLASTIC POLARIZED LENS

摘要

A plastic polarized lens 1 contains a lens substrate 2, which is obtained by curing through polymerization a polymerization composition having a refractive index of 1.60 or more containing a thiourethane polymerization composition or a thioepoxy polymerization composition, having embedded therein a polarized film 14, which is obtained by forming antireflection layers 14B having a five-layer structure of Al₂O₃ ZrO₂ accumulated alternately on both surfaces of a polarized film substrate 14A obtained by curving an iodine polarized film to a prescribed curvature, followed by cutting into a circular outer shape. According to the constitution, such a plastic polarized lens can be obtained that is reduced in reflection on the surface of the polarized film embedded in the polymerization composition and has good polarizing capability.
