Abstract
High productivity polarizing lens that is impact-resistant, and is not prone to warping or iridescent patterning and other color irregularities. Polarizing lens () includes a polarizing sheet () in which a pair of protective films () and () is laminated on both sides of a polarizing film (), and a lens base material layer () integrally bonded on a rear side of the polarizing sheet (), the lens base material layer () being composed of polyurethane. Manufacturable by: bending the polarizing sheet () at a predetermined curvature; fitting the polarizing sheet () in a mold recessed with a cavity contoured to correspond to the bent polarizing sheet so that its front side runs along the cavity; and filling and injection-molding thermoplastic polyurethane into the mold in which the polarizing sheet () has been fit, to form the lens base material layer () on the polarizing sheet () rear side.
