ABSTRACT:
Spectacle-mounted display apparatus in which a reflective surface of a partially-transparent eyeglass lens is employed as the primary optical element. A concave spherical relay reflector is positioned inside the lens/eye cavity. The display ocular is an asymmetrical multi-axial virtual image magnifier which receives the object light on its relay reflector and thereby reflects the object light from the partially reflective surface of the spectacle lens to the wearer's eye to form a virtual image at infinity. In various embodiments of the invention, the ocular display apparatus is employed as a personal display of film, LEDs, fiber optics, CRT or electronic images generated for delivering data to a wearer as a virtual image at infinity.
