Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A device and display for demonstrating glare reduction by a polarized lens includes an array of vertically spaced-apart, parallel, transparent elements. Rays of light polarized in a first dimension are directed onto the array from above. An indicium is positioned behind the array. A reflective surface is positioned adjacent a bottom of the array. A polarized lens having a polarization opposed to the first dimension is interposable between a viewer's eye and the array. In use, rays from the polarized light source impinge upon the array, partially pass to the reflective surface and are partially reflected onto the indicium via glare off the array. Rays reflected by the reflective surface are reflected by the array via glare toward the viewer's eye, and rays reflected by the indicium pass thorough the array toward the viewer's eye. An interposition of the polarized lens shields the viewer's eye from the glare.
