Subsequently, a repeated-measures ANOVA with the within-subjects factor session (session 1–5) and the between-subjects factor optotype (Landolt-C versus Tumbling-E) was conducted and revealed a marginally significant main effect of session (F [3.05, 64.03] = 2.4; p = 0.074; η 2 = 0.10; Huynh-Feldt corrected), but neither a significant main effect of optotype (F [1, 21] = 0.31; p = 0.58; η 2 = 0.015) nor a significant interaction between session and optotype (F [3.05, 64.03] = 0.93; p = 0.43; η 2 = 0.04; Huynh-Feldt corrected).
