An electronic eye depth testing method comprises a three dimensional cubic space displayed on a display screen, wherein the cubic space has a first image of a three dimensional object and a second image of a three dimensional object randomly placed within the cubic space. The first image is located at the intersection of two perpendicular horizontal planes and a vertical plane perpendicular to said two horizontal planes and the second image is located at the intersection of two perpendicular horizontal planes and a vertical plane perpendicular to said two horizontal planes. A subject to be tested for depth perception is directed to move the images into convergence in the center of the cubic space.
