Effect of narrowband light on eye growth in control eyes under different light conditions. Control eyes exposed to blue light showed significantly shorter (a) VCD and (b) AL, and more hyperopic refraction c, d. No significant differences between red and white light were observed. 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 chicks exposed to white light. VCD, vitreous chamber depth; AL, axial length; SER, spherical equivalent refraction; SEM, standard error of mean
