What Is Blindness?

Total blindness typically connotes someone who has a complete lack of light perception, also known as "no light perception" (NLP). Only about 15% of people with eye disorders are totally blind.  Most visually impaired people have some vision.

Low vision refers to people whose vision cannot be completely corrected by glasses, contact lenses, medicine, surgery, magnification aids or assistive technology.

Visual impairment refers to people whose decreased visual function interferes with their ability perform their activities of daily living (ADLs), such as reading, driving, and watching TV. Visual impairment includes those who have low vision or who are blind.
