Measurement of vision, often referred to as visual acuity assessment, determines how well an individual can see and interpret visual information. This is typically evaluated using standardized eye charts, such as the Snellen chart, which measures clarity of vision at various distances. Results are expressed as a fraction, with the numerator indicating the testing distance (usually 20 feet) and the denominator representing the smallest line of letters read correctly. Accurate vision measurement is essential for diagnosing eye conditions and determining the need for corrective lenses or treatments.
