Description
A technically accurate Snellen chart using a full alphabet of optotypes. Print at 16" x 24" and view at 20 feet (6 m) for accurate testing.
The order of the 61 characters on the charts has been limit uniformity and avoid easily perceived patterns. These restrictions (e.g. limit in the number of repeated n-grams) apply across linebreaks.
