What is a Snellen Chart?

The Snellen Chart is a simple yet effective tool for measuring visual acuity. It works by having the individual being tested cover one eye and read the letters on the chart with the other eye, starting from the top and working their way down. The smallest line of letters that the individual can read correctly indicates their visual acuity. For example, if an individual can read the letters on the 20/20 line, it means that they have normal visual acuity. If they can only read the letters on the 20/40 line, it means that they have a visual acuity of 20/40, which is below normal.
