A computer-implemented method for optical element fabrication with optical scanner feedback includes initiating the optical scanner to obtain an optical measurement of an optical layer of a multi-layer film. A rotational orientation for an optical element that is to be cut from the multi-layer film is then determined based on the optical measurement. The method also includes initiating a cutting instrument to cut the optical element from the multi-layer film at the rotational orientation.

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 curved rigid member and a flexible member at a pressure and maintaining the pressure for a time sufficient to allow the lens blank to conform to the shape of the curved rigid member. Methods of the invention may be used to make curved lenses with different polarization properties and curvatures.
