optotype
s were developed by Louise Sloan in 1959. She developed a set of 10
optotype
s that had the same basis as the Snellen
optotype
s, the 5×5 grid. However, Sloan
optotype
s do not use serifs and use a geometric progression. This Sloan chart still uses Snellen equivalents and is calibrated for testing at 10 feet.
