Patent ID: 8100525

Claim:
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 forma 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.
