Visual acuity is expressed as a fraction.
The top number refers to the distance you stand from the chart. This is often 20 feet (6 meters).
The bottom number indicates the distance at which a person with normal eyesight could read the same line you correctly read.
For example, 20/20 (6/6) is considered normal. 20/40 (6/12) indicates that the line you correctly read at 20 feet (6 meters) away can be read by a person with normal vision from 40 feet (12 meters) away.
