The Snellen chart is a widely used tool for measuring visual acuity, which is the sharpness and clarity of vision. It was developed by Hermann Snellen in 1862 and has since become a standard in the field of ophthalmology. The chart typically consists of a series of lines with letters of decreasing sizes, with the largest letters at the top and the smallest at the bottom. By covering one eye and reading the letters on the chart with the other, individuals can determine their visual acuity.
