CURVED LENSES AND RELATED METHODS

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 heating and pressing the lens blank between a convex member and a concave member at a first pressure, ramping the pressure sigmoidally to a higher pressure over a period of time, and maintaining the higher pressure for a time sufficient to allow the lens blank to conform to the shape of the convex member and concave member. Methods of the invention may be used to make curved lenses with different polarization properties and curvatures.
