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.
