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.
Stereopsis recovery, also recovery from stereoblindness, is the phenomenon of a stereoblind person gaining partial or full ability of stereo vision . Recovering stereo vision as far as possible has long been established as an approach to the therapeutic treatment of stereoblind patients.
Coarse stereopsis is important for orientation in space while moving, for example when descending a flight of stairs. Fine stereopsis is mainly based on static differences. It allows the individual to determine the depth of objects in the central visual area (Panum's fusional area) and is therefore also called quantitative stereopsis.
For example, when looking at a picture of a tree, the visual system must determine that the two retinal images of the tree come from the same actual object in space. If the correspondence problem is not overcome in this case, the organism would perceive two trees when there is only one.
A random-dot stereogram (RDS) is stereo pair of images of random dots that, when viewed with the aid of a stereoscope, or with the eyes focused on a point in front of or behind the images, produces a sensation of depth due to stereopsis, with objects appearing to be in front of or behind the display level.
