Lens transmission and pupil responses to blue (470 nm) light Lens transmission of blue light in relation to age Our results revealed a highly significant linear decrease in blue (a peak at 480 nm) light transmission through the lens with increasing age (r = −0.91, p < 0.0001, transmission = 1.08–(0.01 * age), see Figure 4 ).
