Abstract

Stereoscopic eyewear with compound curvature may be employed to view three dimensional content. The manufacture of such eyewear may be achieved by thermoforming a first material and by thermoforming a second material. The first and second materials may be in roll stock form prior to thermoforming, and the first layer may be polarizer material, while the second layer may be retarder material. Each of the first and second materials may be thermoformed by employing optimized thermoforming conditions for each of the two materials. Additionally, the two thermoforming lines may be timed so that the curved shapes of the first material in roll stock form may be substantially synchronized with the curved shapes of the second material in roll stock form, which may allow the curved shapes of each of the first and second materials in roll stock form may be joined together.
