LENS SYSTEM FOR PRESBYOPES WITH INTER-EYE VISION DISPARITY LIMITS

摘要

PROBLEM TO BE SOLVED: To provide a lens system for presbyopes.SOLUTION: A lens system for presbyopes utilizes inter-eye disparity limits to improve vision. The lens system may be utilized to improve binocular vision when viewing distant, intermediate and near objects by requiring a minimal level of inter-eye disparity in vision such that the level of inter-eye disparity is not objectionable to a patient. This disparity in vision depends upon the lens design for each eye and upon how the lenses are fit in each eye relative to the distance refraction of the patient.SELECTED DRAWING: Figure 4
