Abstract
Disclosed herein is a lens for a wearable projection system. The lens includes a holographic optical element embedded within the lens and covering a portion of the viewable area of the lens. The lens can be manufactured by filling a cavity in a lens blank with a photosensitive material and exposing the photosensitive material to a number of light beams to form the HOE.
