Eye care professionals use prism correction as a component of some eyeglass prescriptions. A lens which includes some amount of prism correction will displace the viewed image horizontally, vertically, or a combination of both directions. The most common application for this is the treatment of strabismus. By moving the image in front of the deviated eye, double vision can be avoided and ...

Prism (optics) An optical prism is a transparent optical element with flat, polished surfaces that are designed to refract light.

The most familiar type of optical prism is the triangular prism, which has a triangular base and rectangular sides.

English: White light dispersed by a prism into the colors of the optical spectrum (above stripe) compared to a calculated rainbow (below) and its interference between rays of light following slightly different paths with slightly varying lengths within the raindrop (∅: 0.7mm). The middle stripe is from a real observation of a rainbow.
