Abstract
An ocular projection display (12) projects an image directly to the eye (26) of the user (10). The focus of the image may be varied to allow for different user profiles or to relieve the stress of maintaining a fixed focus over a prolonged period of time. Optionally, the ocular projection display (12) can include a location and distance sensor (46) for identifying the location of the user's eyes for proper aiming of the image to the eyes of the user and focus detection circuitry (54) to correct for the user's focusing abilities.
