The term "condition" has a number of biomedical meanings including the following: 1.An unhealthy state, such as in "this is a progressive condition." 2.A state of fitness, such as "getting into condition." 3.Something that is essential to the occurrence of something else; essentially a "precondition." 4.As a verb: to cause a change in something so that a response that was previously associated with a certain stimulus becomes associated with another stimulus; to condition a person, as in behavioral conditioning.

Bone
Bone refers either to a hardened connective tissue or to one of the individual structures, or organs, into which it is formed, found in many animals. Bones support body structures, protect internal organs, and (in conjunction with muscles) facilitate movement; are also involved with cell formation, calcium metabolism, and mineral storage. The bones of an animal are, collectively, known as the skeleton.

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.

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 personís 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 personís 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.
