STEREOPSIS IN PRESBYOPES FITTED WITH SINGLE VISION CONTACT LENSES*

Abstract

Single vision contact lenses may be used for presbyopes by correcting one eye for distance and the other for near, but a blurred eye might place limitations upon depth perception. Fifty presbyopes fitted with a contact lens for near seeing for the non-dominant eye were tested with a polaroid vectograph to measure stereopsis. 94% of the patients exhibited stereoscopic vision within norms developed by several researchers.
