Devices, systems and methods that include specialized waveguide assemblies are provided for performing light transformations. Some waveguide assemblies include a waveguide and a compensating lens. The waveguide includes a front surface and a back surface, wherein the waveguide is configured to receive external light at the front surface and transmit the external light through the waveguide to the back surface. The compensating lens is located on the back surface and is configured to direct light emitted from the back surface toward an exit pupil proximate the back surface. The compensating lens has an input surface oriented toward the waveguide and an opposing output surface oriented away from the waveguide. The waveguide can sometimes increase a user's field of view with minimal distortion on a mixed reality display.
