Visual Acuity
Visual acuity is a measure of the clarity or sharpness of vision. It is expressed as a fraction, with the numerator representing the distance at which a person can read a standard eye chart, and the denominator representing the distance at which a person with normal vision can read the same chart. For example, a person with 20/20 vision can read the chart from 20 feet away, while a person with 20/200 vision can only read the chart from 200 feet away.
Legal blindness is defined as visual acuity of 20/200 or less in the better eye with the best possible correction. This means that a person with legal blindness has difficulty seeing objects that are more than 200 feet away. This can make it difficult to perform everyday activities, such as reading, writing, and driving.
Visual acuity is an important component of the definition of legal blindness because it provides a quantitative measure of a person’s vision loss.
