Combination effect of dual-power lenses and narrowband light on choroidal thickness (CT). a Lens-wearing alone had no significant effect on CT. b Blue light exposure induced a significant choroidal thickening in lens-wearing eyes but not in control eyes. c Red light exposure induced a significant choroidal thickening in both lens-wearing and control eyes starting from Day 10. Data represents mean ± SEM (n = 8 per condition). *,#Statistically significant at P less than 0.05 (one-way repeated-measures ANOVA with Tukey HSD) when compared to contralateral control eyes exposed to corresponding narrowband light (#) or lens-wearing eyes (*) exposed to white light. SEM, standard error of mean
