What are the different types of eye exam charts?

The Tumbling E and Snellen eye charts are the most widely used eye exam charts. Other less common eye charts include Landolt C, logMAR, Rosenbaum table, Lea Test and Golovin-Sivstev table.

Eye charts are used by health care professionals to measure visual acuity during an eye exam. Eye charts typically consist of rows of optotypes, or symbols that gradually become smaller.

The Snellen eye chart is comprised of letters and is generally used to measure distance vision acuity. The Tumbling E chart is similar to the Snellen. However, instead of letters, the Tumbling E chart just uses "Es" for patients who cannot read or are not familiar with letter symbols.
