snellen eye chart

The Snellen eye chart is that standard eye chart that many of us are all used to seeing when we go for an eye test.

It was designed by a Dutch ophthalmologist who was named Herman Snellen at some point in the 1860s.

There are some other types of commonly used charts such as the Landolt C, and the Lea test but they all do roughly the same thing.

Instructions for printing and using this chart can be found over at it’s source Disabled World.com.
