Abstract
An object of the present invention is to provide a thin and lightweight polarizing lens for use in lightweight sunglasses (in particular, rimless sunglasses) while maintaining the clamping force and mechanical strength of a temple part, and a manufacturing method therefor. The values of: the center thickness v of a polarizing lens A including an injection-molded layer 3 laminated on at least one surface of a polarizing sheet B, the injection-molded layer having a polyamide-based resin; and the flexural modulus of the injection-molded layer 3 are adjusted, thus the predetermined clamping force and mechanical strength of a temple part are obtained even in the case of sunglasses with the thin and lightweight polarizing lens.
