Visual acuity charts were compared in terms of differences between the test and retest results. Four charts were compared: ETDRS chart, Lea screener, Sivtsev chart, and a chart developed at the Institute for Information Transmission Problems (Kharkevich Institute; IITP), Russian Academy of Sciences, and based on modified 3-bar optotypes. According to the results obtained in 33 subjects, the IITP chart provided the best repeatability of measurements.
