Currently, most eye care practitioners in Iran use a Tumbling E chart to assess their patient's visual acuity. This project introduces new principles for the design and use of a Farsi letter chart for the measurement of visual acuity at four meters. A chart employing seven selected Farsi letters, based on a logMAR design was made. The chart was tested against the Bailey-Lovie logMAR and the Tumbling E charts. The subjects of the study were fluent in both English and Farsi.
