Steady-state pupil constriction in young and older individuals. Mean pupillary constriction relative to baseline ± SEM in each age group. Blue bars: blue light at low (L), medium (M), and high (H) irradiances. Green bars: green light at low (L), medium (M), and high (H) irradiances. Effects of wavelength and irradiance levels were significant (*p < 0.05), but there was no difference between age groups and no interaction with age (n.s. not significant).
