Prism adaptation is a sensory-motor adaptation that occurs after the visual field has been artificially shifted laterally or vertically.

A typical application of such a lens is to refocus the correction allowing clear vision at any distance. Unlike with bifocals, near-vision correction is achieved over the entire field of view, in any direction. Switching between distance and near vision is accomplished by re-adjusting the lens, instead of by tilting and/or rotating the head.
