Summary data from LEA SYMBOLS® low-contrast sensitivity test. A, B When calculating total number of successes to discriminate symbols (25 maximum) for each of the three viewing distances (1, 3, and 5 m) significant reductions in FXS scores were observed at 3 m and 5 m. C Although no difference was observed at 1 m of distance, D FXS subjects exhibited significantly lower contrast sensitivity compared to healthy study controls at nominal contrast values of < 5% for 3 m of distance and E at < 10% nominal contrast at 5 m of distance.
