What Does VA Stand For?

VA stands for Visual Acuity

Visual Acuity (VA) refers to the clarity or sharpness of vision, typically measured by the ability to discern fine details at a specified distance. It is a critical parameter in assessing visual performance and is commonly evaluated using standardized eye charts during ophthalmic examinations. VA is expressed in fractional terms, such as 20/20, where the first number indicates the distance of the test subject from the chart and the second number represents the distance at which a person with normal vision can read the same line. Accurate measurement of visual acuity is essential for diagnosing eye conditions and determining the need for corrective lenses or other interventions.
