Abstract

A shaped reflective polarizer has different maximum sags in different directions and has an interior portion rotationally symmetric about a principle axis and a peripheral portion adjacent the interior portion and rotationally asymmetric about the principle axis. An optical system includes a partial reflector and an optical stack including an optical lens and the shaped reflective polarizer disposed on a curved major surface of the optical lens. The 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.
