Abstract:
An optical system including at least a first lens, a partial reflector and a reflective polarizer is described. The optical system has an optical axis such that a light ray propagating along the optical axis passes through the first lens the partial reflector and the reflective polarizer without being substantially refracted. At least one major surface of the optical system is rotationally asymmetric about the optical axis. A major surface of the optical system may have a first portion defined by a first equation and a second portion adjacent the first portion defined by a different equation. The first lens may have a contoured edge adapted to be placed adjacent an eye of a viewer and substantially conform to the viewer's face.

Claim (Index 22):
The optical system of  claim 18 , wherein the lens has a principle axis, the film being disposed on the first major surface, the first major surface having a first maximum sag at a first radius in a first direction from the principle axis and a second maximum sag at a second radius in a second direction from the principle axis, the first direction along a first axis orthogonal to the principle axis, the second direction along a second axis orthogonal to both the principle axis and the first axis, a first ratio of the first maximum sag to the first radius being at least 1.05 times a second ratio of the second maximum sag to the second radius, the second ratio being at least 0.1.
