ABSTRACT:
Fiber-optic imaging bundles are used to transfer images of an object from an objective lens to a eyepiece mounted on a portion of the front surface of a spectacle lens. In one embodiment, the image from a single objective lens is split at the eyepiece end of the fiber bundle in order to present the image to both eyes; in another, each eye has its own objective lens, fiber bundle, and eyepiece for true stereo vision; in another, right and left images from two offset objective lens are selectively colored, as by a dichroic filter, and the two colored images are transferred through a single fiber bundle to a color separator.
