Abstract
Curved lenses configured to decode three dimensional content and method of fabricating the same. The lenses comprise a polyvinylalcohol polarizer film laminated with triacetate on both sides, wherein the polarizer film has a polarizing efficiency equal to or exceeding 99% and a transmittance percentage equal to or exceeding 35% and a retarder film (e.g., norbornene copolymer resin) laminated on a front surface of the polyvinylalcohol polarizer film laminated with triacetate and aligned to produce a desired circular polarization responsive to specified retardation wavelengths.
