Curved lenses configured to decode three-dimensional content on television and computer screens

Abstract

Curved lenses configured to decode three dimensional content and method of fabricating the same. The lenses decode three-dimensional content displayed on televisions or computer monitors. Sheets from which the lenses are cut have either (i) a polarizing axis of 0 degrees relative to horizontal and one sheet has a retarder axis at −45 degrees relative to horizontal and the other sheet has a retarder axis of +45 degrees relative to horizontal; (ii) a polarizing axis of −45 degrees relative to horizontal and one sheet has a retarder axis at 0 degrees relative to horizontal and the other sheet has a retarder axis of 90 degrees relative to horizontal; or (iii) a polarizing axis of +45 degrees relative to horizontal and one sheet has a retarder axis at 0 degrees relative to horizontal and the other sheet has a retarder axis of 90 degrees relative to horizontal.

What is claimed is: 
     
         1 . Glasses configured to decode three dimensional content comprising:
 two lenses having:   a polarizing layer laminated with a polymeric material layer on one or both sides;   a retarder layer laminated to a front of the polarizer layer directly or to the polymeric material to form a sheet, said retarder layer configured to decode a desired circular polarization;   wherein a first blank cut from said sheet is curved into a first lens and a second blank cut from said sheet is curved into a second lens wherein together the first and second lenses are able to decode three dimensional circular polarized content; and   wherein the first blank and second blank are cut from said sheet such that:
 the first and second blank have a polarizing axis of 0 degrees relative to horizontal and one of said first blank or second blank has a retarder axis at −45 degrees relative to horizontal and the other of said first blank or second blank has a retarder axis of +45 degrees relative to horizontal.
