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.
ADDITION: Should I assume that prism correction is unavailable to contact lens wearers? Thanks, Wordreader 18:17, 12 August 2015 (UTC) I'm sorry, make that "Crizal", not Crizol. Is the "fresnel prism" used in eyeglasses the same as this kind of prism? Thanks again, Wordreader 02:42, 15 August 2015 (UTC)
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]
Pritzker was born in Palo Alto, California, on January 19, 1965.He is the son of Donald Pritzker and Sue Pritzker (née Sandel).

LCD in a Texas Instruments calculator with top polarizer removed from device and placed on top, such that the top and bottom polarizers are perpendicular. As a result, the colors are inverted. The optical effect of a TN device in the voltage-on state is far less dependent on variations in the device thickness than that in the voltage-off state.
In this example the first eye, with a −1.00 diopter prescription, is the stronger eye, needing only slight correction to sharpen the image formed, and hence a thin spectacle lens. The second eye, with a −4.00 diopter prescription, is the weaker eye, needing moderate correction to sharpen the image formed, and hence a moderately thick ...
Router with two dozen 10 Gigabit Ethernet ports and three types of physical-layer module. 10 Gigabit Ethernet (abbreviated 10GE, 10GbE, or 10 GigE) is a group of computer networking technologies for transmitting Ethernet frames at a rate of 10 gigabits per second.
