Abstract
This disclosure concerns an interactive head-mounted eyepiece with an integrated processor for handling content for display and an integrated image source for introducing the content to an optical assembly through which the user views a surrounding environment and the displayed content, and an LED lighting system coupled to a light transmissive illumination system of the optical assembly. An optical imperfection of the illumination system directs light from the LED lighting system to uniformly irradiate a reflective image display to produce an image that is reflected through the illumination system to provide the displayed content to the user.
