    en.wikipedia.org/wiki/Aphakia

    Aphakia is the absence of the lens of the eye, due to surgical removal, such as in cataract surgery, a perforating wound or ulcer, or congenital anomaly. It causes a loss of ability to maintain focus ( accommodation ), high degree of farsightedness ( hyperopia ), [1] and a deep anterior chamber. Complications include detachment of the vitreous or retina, and glaucoma .

    en.wikipedia.org/wiki/Aberrations_of_the_eye

    The eye, like any other optical system, suffers from a number of specific optical aberrations. The optical quality of the eye is limited by optical aberrations, diffraction and scatter. [1] Correction of spherocylindrical refractive errors has been possible for nearly two centuries following Airy's development of methods to measure and correct ocular astigmatism. It has only recently [when ...

    I removed the Prentice rule example, because it is not written for a nonspecialist audience.

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 ...

  7. Prism (optics) - Wikipedia

    en.wikipedia.org/wiki/Prism_(optics)

    Prism (optics) An optical prism is a transparent optical element with flat, polished surfaces that are designed to refract light. At least one surface must be angled — elements with two parallel surfaces are not prisms. The most familiar type of optical prism is the triangular prism, which has a triangular base and rectangular sides.
