Abstract
A display system includes an optical system and a curved display disposed to emit light toward the optical system. The optical system includes at least a first optical lens, a partial reflector and a reflective polarizer. The optical system has an optical axis such that a light ray propagating along the optical axis passes through the first optical lens the partial reflector and the reflective polarizer without being substantially refracted. At least one major surface of the optical system can be 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 optical lens may have a contoured edge adapted to be placed adjacent an eye of a viewer and substantially conform to the viewer's face.
