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, wherein the image source comprises a lighting system that directs light from a light source to a curved polarizing film that reflects a portion of the light to a reflective image display. The ratio of the height of the curved polarizing film to the width of the reflective image display is less than 1:1.
