A polarizing sheet for a corrective polarizing plastic lens in which the polarizing sheet is formed by appropriate bending of a laminated sheet produced by laminating polycarbonate support layers to both sides of a thin polarizing layer, a method and an apparatus for producing such a polarizing sheet, and a corrective polarizing plastic lens that uses the polarizing sheet. The polarizing sheet comprises an aspheric curved surface in which the degree of curvature varies continuously from the center of the curved surface toward the outer periphery, and is formed by subjecting an intermediate product, formed by a first bending process, to a subsequent second bending process.
