Abstract
Abstract A cornea-borne image and light display device (10) comprising a pair of scleral-rider devices (10), (20) similar to contact lenses, which mount on the corneas of the viewer's eyes to present images within the viewer's eyes. The images to the devices is supplied through a respective fiber-optic bundle (14), (16) that derives its light from a light projector (12). Two embodiments are presented, in one, the fiber-optics directly transmit the light source from the projector (12), in the second the optic fibers reflect the light from a plurality of mirrors embedded within the device.

Claim 1
Independent Claim

A cornea-borne image and light display device comprising: (a) projector means for generating desired images, (b) a pair of viewing scleral-riders positionable on the corneas of the viewer's eyes where an opaque layer covers the outer surface of said scleral-riders and a plurality of mirror surfaces are formed on the inner surface of said opaque layer, and (c) a pair of fiber-optic bundles each connecting said projector means to a respective end of said scleral-riders where the individual optical fibers of each of said bundles extend into said scleral-riders and terminate adjacent to one of said mirror surfaces to cause light from said optical fibers to be reflected by said mirror surfaces to the retina of the viewer's eye.
