Snellen Eye Chart Tie.
A Snellen chart is an eye chart used by eye care professionals and others to measure visual acuity. Snellen charts are named after the Dutch ophthalmologist Herman Snellen who developed the chart during 1862. Vision scientists now use a variation of this chart, designed by Ian Bailey and Jan Lovie.
