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.
A shaped reflective polarizer having a principle axis and a major axis along a projection onto a plane orthogonal to the principle axis of a line connecting two points farthest from each other on the shaped reflective polarizer, the reflective polarizer comprising a plurality of polymeric layers and configured to substantially transmit light having a first polarization state and substantially reflect light having an orthogonal second polarization state, the reflective polarizer stretched and shaped so as to have a first maximum sag in a first direction and a different second maximum sag in an orthogonal second direction, the shaped reflective polarizer having an interior portion rotationally symmetric about the principle axis and a peripheral portion adjacent the interior portion and rotationally asymmetric about the principle axis.
