<P>PROBLEM TO BE SOLVED: To provide a plastic polarized lens having reduced reflection on the surface of the polarized film embedded in the polymerization composition and good polarizing capability. <P>SOLUTION: The plastic polarized lens 1 has: a lens substrate 2, which is obtained by curing through polymerization a polymerization composition having a refractive index of 1.60 or more and comprising a thiourethane polymerization composition or a thioepoxy polymerization composition; and a polarized film 14, which is embedded in the lens substrate 2 and is obtained by forming antireflection layers 14B having a five-layer structure of Al<SB>2</SB>O<SB>3</SB>and ZrO<SB>2</SB>accumulated alternately on both surfaces of a polarized film substrate 14A obtained by curving an iodine polarized film to a prescribed curvature and cutted into a circular outer shape. <P>COPYRIGHT: (C)2008,JPO&INPIT |
