Stereoblindness

Stereoblindness (also stereo blindness) is the inability to see in 3D using 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 always have this condition; the condition also results when two eyes do not function together properly.

It has been suggested that Dutch Old Master Rembrandt may have been stereoblind, which would have aided him in flattening what he saw for the production of 2D works. Scientists have suggested that more artists seem to have stereoblindness when compared with a sample of people with stereo-acuteness (normal stereo vision).

British neurologist Oliver Sacks lost his stereoscopic vision in 2009 due to a malignant tumor in his right eye and now has no remaining vision in that eye. His loss of stereo vision was recounted in his book The Mind's Eye, published in October 2010.

In 2012 one case of stereoblindness was reportedly cured by watching a 3D film.
