  2. Stereoblindness - Wikipedia

    en.wikipedia.org/wiki/Stereoblindness

    Stereoblindness (also stereo blindness) is the inability to see in 3D using stereopsis, or stereo vision, resulting in an inability to perceive stereoscopic depth by combining and comparing images from the two eyes. Individuals with only one functioning eye have this condition by definition since the visual input of the second eye does not exist.

    Oliver Sacks was the first to make the story of Susan Barry, whom he nicknamed "Stereo Sue", known to the general public.. Stereopsis recovery has been reported to have occurred in a few adults as a result of either medical treatments including strabismus surgery and vision therapy, or spontaneously after a stereoscopic 3D cinema experience.

    In the 19th century Charles Wheatstone determined that retinal disparity was a large contributor to depth perception. [1] Using a stereoscope, he showed that horizontal disparity is used by the brain to calculate the relative depths of different objects in 3-dimensional space in reference to a fixed point.
