plane perpendicular to the two vertical planes, wherein a subject to be tested moves the images into convergence in the center of the cubic space.
It is therefore an object of this invention to provide an electronic eye depth testing method and apparatus comprising a three dimensional cubic space displayed on a display screen, the cubic space having a first image of a three dimensional object and a second image of a three dimensional object, the first and the second images randomly placed within the cubic space wherein a subject to be tested moves the two images into convergence in the center of the cubic wherein the first image is initially located at the intersection of two perpendicular vertical planes and a horizontal plane perpendicular to the vertical planes,and the second image is initially located at the intersection of two perpendicular vertical planes and a horizontal plane perpendicular to the vertical planes.
It is yet another object of this invention to provide an electronic eye depth testing method and apparatus comprising a three dimensional cubic space displayed on a display screen, the cubic space having a series of horizontal planes extending through the side walls and through the rear wall and the front wall, a first series of vertical planes extending through the rear wall and front walls and through the top and bottom walls, and a second series of vertical planes extending through the bottom and top walls and the side walls of the cubic space.
Yet another object of this invention is to provide an electronic
