A NEW THEORY OF BINOCULAR VISION

Arch Ophthalmol. 1935;13(2):151-175. doi:10.1001/archopht.1935.00840020011001
Abstract

The perception of depth in stereoscopic vision is obviously dependent on the spatial differences in the two retinal images of the view, for it is known that the act of convergence is not an essential factor in this perception. For the brain to detect these differences, the representations of the two retinas in the brain must be accurately correlated. A retinal area in one eye and another in the other eye between which, during stereoscopic vision, the brain cannot distinguish any spatial difference may be called corresponding retinal areas, and images on such areas must appear to coincide. Anatomic, clinical and experimental observations have conclusively shown that in the occipital lobes the two retinas are represented spatially. But just how precisely each retina is represented in the brain is not really known. The visual acuity of each eye is normally so great, however, especially as revealed by the alinement
