Optics and Vision by Frank L. Pedrotti,
Optics and Vision by Frank L. Pedrotti,
This applications-oriented book covers a variety of interrelated topics under the study of optics. For physics and engineering, it covers lasers and fiber optics, emphasizing applications to the optics of vision. For optometry, it discusses the optics of the eye, geometrical optics, interference, diffraction, and polarization. Emphasizing the optics of vision, the book presents a vital and interesting applications of optical principles. It also includes several specialized sections on vision: a history of vision and spectacles; the use of vergences to handle refraction of the eye; the use of vergence to handle errors in refraction of the eye; optics of cyndrical lenses and application to astigmatism; aberrations in vision; structures and optical models of the eye; and the use of lasers in therapy for ocular defects. A valuable reference on optics for professional optometrists, physicists, and engineers.



Cornea - The cornea is the transparent front part of the eye that covers the iris, pupil, and anterior chamber and provides most of an eye's optical power Together with the lens], the cornea [[refraction|refracts light and consequently helps the eye to focus. The cornea gives a larger contribution to the total refraction than the lens, but whereas the curvature of the lens can be adjusted to "tune" the focus, the curvature of the cornea is fixed.

Eye bank - Eye banks retrieve and store eyes for cornea transplants and research. US eye banks provide tissue for about 46,000 cornea transplants a year to treat conditions such as keratoconus and cornea scarring.

Cornea transplant - A cornea transplant, also known as a corneal graft or penetrating keratoplasty, is a surgical procedure where a damaged or diseased cornea is replaced by donated corneal tissue which has been removed from a recently deceased individual having no known diseases which might affect the viability of the donated tissue. The cornea is the clear part of eye in front of the iris and pupil.

Trabecular meshwork - The trabecular meshwork is an area of tissue located around the base of the cornea, near the ciliary body, and is responsible for draining the aqueous humour from the eye via the anterior chamber (the chamber on the front of the eye covered by the cornea). The tissue is spongy and allows fluid to drain into a set of tubes called Schlemm's canal flowing into the blood system.

The eye is typically roughly spherical, filled with a focusing lens and often a muscle called the iris that controls how much light enters.
