Abstract
When a meridional size lens1 is placed with its axis in the vertical position (at 90 degrees) in front of one eye of a normal observer, the retinal image of that eye is enlarged in the horizontal meridian. Since horizontal disparity of the retinal images is responsible for stereoscopic effects, the observer will experience typical changes in the appearance of his environment. If the size lens is placed in front of the right eye, objects located in the right half of the observer's field of vision appear larger yet farther away from him than objects of the same size situated at the same distances from the observer but located in the left half of his field of vision. A flat desk top will appear to be slanting down on the right side and slanting up on the left side ; a wall perpendicular to the observer's line of gaze willKeywords
