Abstract
3-D eyewear system designed to be worn in association with vertically polarized eyewear (prescription or non-prescription) and method of correcting for vertical polarization for 3-D projections are disclosed. The 3-D eyewear is designed to correct for a vertically polarized underlying optic such that a viewer can use their polarized eyewear while viewing a 3-D stereoscopic movie.
Claims14
A set of mixed-use three-dimensional eyewear comprising:
- an underlying optic comprising at least a pair of vertically polarized lenses;
- and
- a polarization correcting optic incorporating one or more wave retarders, said wave-retarders with their own individual retardation levels being oriented to each other and designed to rotate the vertical polarization of the underlying optic to match the polarization of a projected stereoscopic image.
A method of correcting the vertical polarization of an optic for use with three-dimensional projections comprising:
- providing a polarization correcting optic incorporating one or more wave retarders, said wave-retarders with their own individual retardation levels being oriented to each other and designed to rotate the vertical polarization of the underlying optic to match the polarization of a projected stereoscopic image.
