ABSTRACT:
A vision compensation system includes a lens receiving frame with a pair of lens members, at least one of which has variable optical compensation capabilities. Carried by the frame are means for producing a signal as a function of the relative angular positions of the eyes of the wearer and means responsive to that signal for changing the optical characteristics of the variable lens to provide compensation for impaired accommodative capacity of the wearer's eye.
