Abstract
An eyepiece for a head mounted display includes a light relay body, a total internal reflection ('TIR') interface, and a focusing lens. The light relay body has a first end coupled to receive CGI light from an image source and a second end including a viewing region from which the CGI light is emitted. The TIR interface is disposed in the viewing region at an oblique angle relative to an eye-ward side of the light relay body through which the CGI light is emitted from the eyepiece. The TIR interface is oriented to redirect the light towards the eye-ward side of the light relay body. The focusing lens is disposed along the eye-ward side of the light relay body in alignment with the TIR interface to bring the CGI light into focus for a near-to-eye arrangement.
