Low-cost circular polarizing eyewear

A method for constructing circularly polarized eyewear comprising:

• providing substantially rigid material;
• and
• providing polarizing lensing material with retarder lensing material free of lamination by fixedly maintaining the polarizing lensing material and the retarder lensing material in association with said substantially rigid material;
• wherein said polarizing lensing material and said retarder lensing material enable each eye of a user to receive an intended image and an unintended image is blocked when used in conjunction with suitably polarization encoded projected images.

An apparatus comprising:

• substantially rigid material configured to receive and maintain lensing material;
• polarizing lensing material located proximate the substantially rigid material;
• and
• retarder lensing material matched to the polarizing lensing material and positioned adjacent to the polarizing lensing material;
• wherein the polarizing lensing material and retarder lensing material are fixedly maintained in association with the substantially rigid material and are configured to be provided free of lamination to form circular polarizing eyewear.
