artificial v. An experimental technique to make it possible for some blind people to see as a result of electrical stimulation of the retina or the connection of digital video cameras to the visual cortex of the brain.
binocular v. The visual sensation produced when the images perceived by each eye are fused to appear as one.
central v. Vision resulting from light falling on the fovea centralis.
