CURVED CORRECTIVE LENSES CONFIGURED TO DECODE THREE-DIMENSIONAL CONTENT
Curved corrective lens configured to decode three dimensional content. The corrective lens may include a wafer formed of a high efficiency polarizer material layer over a lamination layer over an adhesion layer over a retardation layer, and a lens material to which the wafer is integrated and into which a prescription is ground. Photochromic materials may also be used to provide a self-darkening feature.
