Abstract

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.

Claims

1. A curved corrective lens configured to decode three dimensional content comprising:

a wafer formed of a high efficiency polarizer material layer over a lamination layer over an adhesion layer over a retarder layer; and

a lens material to which said wafer is integrated and into which a prescription is ground.

2. The lens of claim 1 wherein said polarizer material layer is tinted with iodine crystals or dichroic dyes.

3. The lens of claim 1 wherein said wafer further comprises a second lamination layer on an opposite side of said polarizer material layer.

4. The lens of claim 1 wherein said wafer further comprises a second adhesion layer for facilitating bonding between said wafer and said lens material.

5. The lens of claim 1 wherein said wafer and lens material are integrated using injection molding, casting and/or lamination techniques.

6. The lens of claim 1 wherein said polarizer material layer comprises one or more of the following:

polyvinylalcohol or polyethylene terephthalate.

7. The lens of claim 1 wherein said lamination layer comprises one or more of the following:

polycarbonate, poly(methyl methacrylate), polystyrene, polyamide, cellulose acetate butyrate (CAB), cellulose acetate, cellulose diacetate (DAC) or cellulose triacetate (TAC).

8. The lens of claim 1 wherein said lens material comprises one or more of the following:

polycarbonate, polyurethane, polysulfone, cellulose ester resin, homopolymer, copolymer of (meth)acrylates, polyamide, copolymer of olefin, or copoloymer of cycloolefin.

9. The lens of claim 1 wherein said retarder layer comprises one or more of the following:

copolymer resin, film, polyurethane, polycarbonate or polyvinylalcohol (PVA).

10. The lens of claim 1 further comprising a photochromic triactetate layer between said retarder layer and polarizer layer.

11. The lens of claim 1 further comprising a photochromic coating over said lens material.

12. A method of fabricating a curved corrective lens configured to decode three dimensional content comprising:

forming a wafer having a high efficiency polarizer material layer over a lamination layer over an adhesion layer over a retardation layer;

integrating said wafer with a lens material; and

grinding a prescription into said lens material.

13. The method of claim 12 further comprising tinting said polarizer material layer with iodine crystals or dichroic dyes.

14. The method of claim 12 further comprising forming said wafer having a second lamination layer on an opposite side of said polarizer material layer.

15. The method of claim 12 further comprising forming said wafer having a second adhesion layer for facilitating bonding between said wafer and said lens material.

16. The method of claim 12 further comprising integrating said wafer and lens material using injection molding, casting and/or lamination techniques.

17. The method of claim 12 further comprising forming said wafer utilizing a polarizer material layer having one or more of the following:

polyvinylalcohol or polyethylene terephthalate.

18. The method of claim 12 further comprising forming said wafer utilizing said lamination layer having one or more of the following:
