Stereoblindness

Stereoblindness (also stereo blindness) is the inability to see in 3D using stereo vision, resulting in inability to perceive stereoscopic depth.

Individuals with only one eye always have this condition; the condition also results when two eyes do not work in proper concert.

It has been asserted that the Dutch painter Rembrandt may have been stereoblind, which would have aided him in flattening what he saw for the production of 2D works.
