Changes in the accommodative response and pupil diameter according to static refractive stimuli (100, 50, 33, 25, and 20 cm). a, b Accommodative response of the right eye shows significant changes according to refractive stimuli. However, there is no significant change in pupil diameter according to the refractive stimuli, except between 33 and 25 cm (Kruskal-Wallis test, Dunn’s multiple comparison test, P = .005). c, d Accommodative response of the left eye shows significant changes according to the refractive stimuli; however, there is no significant change in pupil diameter according to the refractive stimuli. *P-value by Kruskal-Wallis test, Dunn’s multiple comparison test; significance was set at < 0.05
