Visual acuity is a measure of the spatial resolving power of the visual system; it indicates the angular size of the smallest detail that can be resolved. Visual acuity is measured for various purposes. When determining the appropriate eyeglasses, the corrective lens power that permits the best visual acuity is prescribed. In the diagnosis and monitoring of eye diseases that may affect vision, changes of visual acuity are often taken to indicate the presence and magnitude of change in the eye condition. Visual acuity measurements are also used by some licensing authorities and employers as eligibility criteria for some occupations (e.g., airline pilot, police officer) and activities (e.g., driving). Visual acuity has traditionally been used as the primary indicator of the magnitude of functional impairment due to vision loss.

Good visual acuity is important for a variety of everyday tasks in the workplace, but probably is most important for reading text and interpreting symbols. The visual acuity demand for a given task depends on the minimum size of the detail in the task and the observation distance. For example, a person with good visual acuity might be expected to recognize faces at about 20 meters. To recognize the same faces, a person with poor visual acuity would have to get significantly closer.
