An eye chart, also known as a visual acuity chart, is a tool used by eye care professionals to measure a person’s visual acuity, or the sharpness of their vision. The chart consists of rows of letters or symbols that progressively decrease in size from the top to the bottom. The person being tested is asked to read the letters or identify the symbols from a specific distance, usually 20 feet (or 6 meters) for standard eye charts.
