Visual Acuity Tests

Visual acuity tests measure how well you see at different distances by asking you to read letters or symbols on a chart, usually from a standard distance. The most common chart is the Snellen chart, which features rows of letters decreasing in size. These tests help eye care professionals determine if you need glasses, contacts, or other vision correction. Your results are expressed as a fraction (e.g., 20/20), indicating how clearly you see compared to a person with normal vision. Regular testing helps monitor your eye health and detect any changes in your vision over time.
