Abstract
Eyewear having an optical waveguide communicating infrared light from a remote infrared emitter in the eyewear to an optical output coupler that uniformly illuminates an eye for tracking eye movement of a user. An optical input coupler couples a light beam emitted by the remote infrared emitter into the waveguide. The remote infrared emitter simplifies industrial design and is a single light source. The remote infrared emitter is not in a peripheral vision of a user's eye and improves a cosmetic impact.
