What Is the Function of a LogMAR Chart?
The logMAR chart, also known as an ETDRS chart, is an assessment tool used by optometrists and eyecare specialists to measure a patient's visual acuity level (i.e., 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.
Key Features and Benefits
- ETDRS logMAR test type chart
- Ideal for testing a patient's near-distance visual acuity
- Suitable for use by optometrists, doctors, and vehicle licensing agencies
- Designed for conducting near-vision tests at a 2 metre distance

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 so are 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.
