摘要： Curved lenses and methods for making curved lenses are described. One embodiment of a method of making a curved lens includes curving a lens blank made of a linear polarizer layer laminated together with a plurality of polymeric layers. The lens blank is curved by engendering rotational motion about a rotational axis of a roller having a forming surface thereon and lateral motion of a belt in contact with the forming surface. The lens blank is heated and pressed between the belt and the forming surface at a pressure, the pressure being supplied by tension on the belt. The pressure is maintained for a time sufficient to allow the lens blank to conform to the shape of the forming surface. Methods of the invention may be used to make curved lenses with different polarization properties and curvatures.
