Laptops are widely used even in dark scotopic rooms. This study compares monocular accommodation statuses with laptop usage under three illuminations. Thirty university students read on a laptop for 5 minutes under scotopic, mesopic, and photopic conditions. The monocular amplitude of accommodation, accommodation facility, and accommodation error are measured for each illumination. Repeated measure ANOVA shows a significant difference in the amplitude, facility, and error between different illuminations [F (1.49, 43.18) = 10.61, p<0.001], [F (1.65, 36.30) = 6.78, p=0.005] and [F (2, 56) = 3.65, p=0.032]. Scotopic illumination reduces monocular accommodation abilities with laptop usage.
