Abstract
A contact lens set for stereoscopic visualization includes a left contact lens comprising a first lens substrate incorporating a first polarizer, and a right contact lens comprising a lens substrate incorporating a second polarizer. The first polarizer comprises a first plurality of parallel lines having sub-wavelength pitch and oriented in a first direction. The second polarizer comprises a second plurality of parallel lines having sub-wavelength pitch and oriented in a second direction. The left contact lens and the right contact lens each comprises a rotational stabilization means, such that, during use, the first direction is adapted to orient in an approximately orthogonal direction to the second direction. In another embodiment, a contact lens set for stereoscopic visualization includes a left contact lens and a right contact lens, each coded with different colors.
