Abstract
PURPOSE:To obtain a polycarbonate polarizing lens, which has little optical strain and is excellent in shock resistance and the like, by a method wherein the kind of thin polarizing layer, the thickness of laminate, thermal working conditions and the like are set in specified ranges. CONSTITUTION:The kind of thin polarizing layer, the thickness of laminate, thermal working conditions and the like to be set within specified ranges are as follows: the thin polarizing layer is produced by orientating dichroic dyestuff onto a polymer film. The laminate having a thickness of 0.5-2.5mm is manufactured by laminating polycarbonate films or sheets onto both the sides of said thin polarizing layer. Said laminate is heated up to a temperature, which is not lower than 135 deg.C and not higher than by 30 deg.C above the glass transition temperature of the polycarbonate. Further, a pressure of not higher than 1.2kg/cm<2> is gradually loaded to said laminate before said laminate reaches the glass transition temperature of the polycarbonate so as to shape said laminate into a curved surface having a radius of curvature of 80mm or more. Thus, a polycarbonate polarizing lens, which has little optical strain and is excellent in shock resistance and the like, can be obtained.
