The Snellen's Chart is a chart developed in 1862 by the Dutch ophthalmologist Herman Snellen, the son of the renowned physician, Dr. F. A. Snellen. The younger Snellen studied medicine in The Netherlands under Gerard Johann Mulder, Jacobus Ludovicus Conradus Schroeder van der Kolk, and Franz Cornelis Donders. He received his medical doctorate at Utrecht in 1858.
Dr. Snellen's chart is used to measure the percentage of loss of visual acuity.
