What Is the Function of a LogMAR Chart?
An ETDRS or logMAR eye-test chart is designed to assess a patient's visual functioning, usually in relation to visual acuity (or the distance at which they can see clearly). This particular chart is designed with lines consisting of 5 Sloan optotypes each that decrease in size further down the chart.

Original Versus Revised ETDRS Charts
The original ETDRS logMAR charts are the only standardised choice for studies sponsored by the American National Eye Institute, and are generally the preferred option for clinical studies, low vison evaluations, and gathering repeatable visual acuity measurements.
The revised charts offer a different scoring system, and a different arrangement of the included letters.
