ABSTRACT:
There is disclosed herein a vision aid for doctors, dentists, visually-handicapped, engineers, mechanics, technicians, and the like. The device comprises a conventional eyeglass frame having mounted thereto a pair of plastic elevating plates and which are hinged with respect to the eyeglass frame. One monocular, or a pair of monoculars forming a binocular, can be secured to the elevating plates. The elevating plates are connected together and attached to the hinges in a manner to allow the interocular or pupil distance to be readily set or readjusted, and also allow the monoculars to be adjusted up and down vertically with respect to the axis of the wearer's eyes. The hinged arrangement allows the elevating plates to tilt up to thereby move the monocular or monoculars out of the line of vision, so as to restore the wearer's natural vision or vision as corrected by corrective lenses in the eyeglass frames. The monoculars also are mounted in a manner to allow alignment and re-alignment of the axis of the monoculars to toe in or toe out these lenses so that it can be parrallax adjusted for any close working distance to allow for exact collimation. The overall assembly is relatively simple, compact and lightweight. The monoculars can be fixed focus but generally are lenses of variable focus.
