Comparison of pupil sizes (mean + standard deviation) between TT ( n = 31; black bars) and TC + CC ( n = 38; white bars) genotypes. (a) Blue conditions, (b) green conditions, (c) red conditions. Pupil sizes of TC + CC were significantly smaller than those of TT under the 15-blue condition, but there were no significant differences under green and red conditions. *P < 0.05.
