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 24):
The optical system of  claim 18 , wherein the film is a shaped optical film having a projected area in a first plane, the shaped optical film being disposed on one side of the first plane, the first plane being such that a maximum area of any region of a second plane bound by any closed convex curve defined by an intersection of the shaped optical film with the second plane is largest when the second plane is parallel to the first plane, the projected area having a centroid, a length along a first axis and a width along an orthogonal second axis, each of the first axis and the second axis being disposed in the first plane and passing through the centroid, the width being a minimum length along any line segment in the first plane passing through the centroid and connecting opposite points on a boundary of the projected area, the shaped optical film having a first maximum sag being a difference in the maximum and minimum displacements from the first plane of the shaped optical film along the first axis, the shaped optical film having a second maximum sag being a difference in the maximum and minimum displacements from the first plane of the shaped optical film along the second axis, a first ratio of the first maximum sag to the length being at least 1.01 times a second ratio of the second maximum sag to the width, the second ratio being at least 0.05.
