Zusammenfassung:	The present invention relates to a polarizing lens molded by inserting a polarizing sheet bent into a sphere or an asphere after having an aromatic polycarbonate sheet bonded via an adhesive layer to both surfaces of a film with polarized nature into a mold, and injecting aromatic polycarbonate, wherein heat treatment at a temperature not less than a temperature of 50° C. lower than the glass transition point and less than the glass transition point for an appropriate time has been performed after injecting aromatic polycarbonate to approximate a designed value of the lens curvature.
