PROBLEM TO BE SOLVED: To provide a polarizing lens which is manufactured by subjecting a polarizing plate made by laminating a protective layer on a polarizable thin film to curved surface processing, which is utilized for glare shielding sunglasses, goggles or the like, which has shock resistance and heat resistance and which is free from peeling and production of a colored interference fringe. SOLUTION: The polarizing plate is produced by laminating the protective layer (A) made of a triacetyl cellulose film on one surface of the polarizable thin film and laminating the protective layer (B) made of a mixed resin composed of a polycarbonate resin and a polyester series resin on another surface thereof. Then the polarizing plate is subjected to curved surface molding to produce the polarizing lens in which a thermoplastic resin (C) is laminated on the protective layer (B) side by an insert mold method. In the polarizing lens, a mixing ratio of the polycarbonate resin with the polyester series resin in the mixed resin is 80 to 20/20 to 80, the polyester series resin is synthesized by a dicarboxylic acid component consisting of terephthalic acid, 1,4-cyclohexane dimethanol and ethylene glycol. 1,4-cyclohexane dimethanol is consisting of diol components of 40 mol.% or more.
