Abstract

A viewing assembly for viewing a two dimensional object in three dimensions is disclosed which has vision directing means for converging the lines of sight of a user of the viewing assembly to direct the sight of each eye of the user to predetermined segments of an object being viewed, the predetermined segments being laterally spaced and partially overlapping, the angle of convergence of the lines of sight being such that the lines of sight of each eye intersect at a point between the eyes and the object whereby a segment to the left of the object is viewed by the right eye and a segment to the right of the object is viewed by the left eye. A method of ocular therapy is also disclosed wherein the vision of a patient is conditioned by viewing an object using the viewing assembly.
