Accommodation In younger people, under age 40, the lens is adjusted by the ciliary muscles to focus clearly for near as well as far vision. With age the lens is less able to change, eventually requiring reading glasses or bifocals for close work.
RELATED TERMS--------------------------------------
Lens
The lens of the eye is like an adjustable lens of a camera and focuses light rays on to the retina for sharp images. A condition called presbyopia occurs when the lens is no longer able to adjust for objects at different distances.
Vision
The sense of sight.
Bifocals
Eyeglasses with divided lenses. The two parts of each lens have different strengths, allowing the wearer to focus the eye for either near or distant vision.
SIMILAR TERMS--------------------------------------
Accolate
Accolate is a prescription or over-the-counter drug which is (or once was) legal in the United States and possibly in other countries. Active ingredient(s): zafirlukast.
Accoucheur
French for a male obstetrician, a physician skilled in the art and science of managing pregnancy, labor and the puerperium (the time after delivery).
Accoucheuse
"French for a woman who is an obstetrician (a physician skilled in the art and science of managing pregnancy, labor and the time after delivery) or a midwife (today a non-physician trained to assist a woman during childbirth). The ending ""-euse"" is feminine and indicates that the accoucheuse is a woman."
PREVIOUS AND NEXT TERMS--------------------------------------
Apligraf

Accommodation
Achromatopsia
Characterized by a lack of color vision with poor visual acuity, nystagmus, and sensitivity to sunlight. No treatment is available except, for example, sunglasses for the sensitivity to light.
Age Related Macular Degeneration
The most common form of macular degeneration is Age-related Macular Degeneration (ARMD). It is believed that one contributing factor of ARMD is excessive light exposure over a person’s lifetime. Limiting excessive light exposure (e.g., wearing sunglasses and a hat outside) and a diet rich in antioxidants as well as zinc may prevent or retard the development of ARMD. In general, the lighter a person’s complexion the greater the risk of ARMD.
Albinism
A hereditary condition in which darker pigment fails to form in the eye, hair and skin. In ocular albinism, visual acuity ranges from 20/40 to 20/200 (legal blindness), the eyes may dance (nystagmus) and the person is very sensitive to sunlight. No treatment is available, except dark sunglasses for the photophobia.
Angioid Streaks
Fragmentation of Bruch’s membrane due to the degeneration of the elastic layers and development of subretinal fibrovascular tissue. Sometimes does not cause vision problems; however, can cause a reduction of visual acuity leading to legal blindness. Often associated with another disease such as sickle cell disease and certain syndromes.
