Visual Acuity
Visual acuity refers to the clarity or sharpness of vision, which is typically measured using a standard eye chart. It indicates how well a person can see details at a specific distance, often expressed as a fraction, such as 20/20. A higher number in the denominator indicates poorer vision, while a lower number signifies better visual clarity.
Factors affecting visual acuity include eye health, lighting conditions, and distance from the object being viewed. Regular eye examinations can help detect issues that may impair visual acuity, allowing for timely interventions such as corrective lenses or other treatments.
