Any loss of sight other than total blindness is usually considered a visual impairment — not a disability. There is a wide range of vision exhibited by people who have a visual impairment. This can range from total blindness through various levels of increased blindness to total blindness, or the inability to perceive light or movement.
In the United States, blindness ranks third in terms of the health problems most feared by the public after cancer and AIDS. Legal blindness does not necessarily mean total blindness; 90% of people who are legally blind have some vision.
Formally, a person is legally blind if their central visual acuity is 20/200 or lower in the best vision eye, even with corrective lenses or if he has a central visual acuity of more than 20/200 if the peripheral field is limited to a diameter of 20 degrees or less. Informally, people who, even with corrective lenses, can not read the largest letter in an eye chart are considered legally blind.
