Prism spectacles with a single prism perform a relative displacement of the two eyes, thereby correcting eso-, exo, hyper- or hypotropia. In contrast, spectacles with prisms of equal power for both eyes, called yoked prisms (also: conjugate prisms , ambient lenses or performance glasses ) shift the visual field of both eyes to the same extent.
Prism lighting is the use of prisms to improve the distribution of light in a space. It is usually used to distribute daylight , and is a form of anidolic lighting . Prism lighting was popular from its introduction in the 1890s through to the 1930s, when cheap electric lights became commonplace and prism lighting became unfashionable.
Photograph of a triangular prism, dispersing light Lamps as seen through a prism. In optics, a dispersive prism is an optical prism that is used to disperse light, that is, to separate light into its spectral components (the colors of the rainbow). Different wavelengths (colors) of light will be deflected by the prism at different angles. [1]

In a dispersive prism, material dispersion (a wavelength-dependent refractive index) causes different colors to refract at different angles, splitting white light into a spectrum. A compact fluorescent lamp seen through an Amici prism. Dispersion is the phenomenon in which the phase velocity of a wave depends on its frequency. [1]
A Nicol prism is a type of polarizer. It is an optical device made from calcite crystal used to convert ordinary light into plane polarized light . It is made in such a way that it eliminates one of the rays by total internal reflection , i.e. the ordinary ray is eliminated and only the extraordinary ray is transmitted through the prism .
Rainbow Brite is an animated series based on Hallmark's media franchise of the same name, that ran from 1984 to 1986. [3] Produced by DIC Enterprises with animation provided by Japanese TMS Entertainment, the show began as a part of DIC's Kideo TV syndicated anthology package. [4]
