ABSTRACT:
Telemicroscopes mounted to spectacle lenses extend rearwardly from the lenses toward a patient's eyes. The telemicroscopes are miniaturized and provide an extended depth of field and a field of view ranging from 8 degrees to 20 degrees. The spectacle lenses are shaded to increase the field of view, and the image viewed through the telemicroscopes matches the perceived outer diameter of the telemicroscopes. With the very small scopes positioned at about the center viewing axis of the eye, bilevel viewing in which a magnified image and a nonmagnified image are simultaneously viewed is possible. Several telemicroscopes may be mounted in a cluster for panoramic viewing.
