Fig 5. Biological validation of filtered lights (N = 16).
Pupillary Light Reflex (PLR) parameters calculated under light filtered with uncoated (used as control), transmissive and absorptive states: A) Maximum pupil constriction, with respect to the baseline; B) post-illumination pupil response 6 seconds after the end of the 1-s light stimulus (6s-PIPR), expressed as % constriction respect to baseline; C) Area Under the Curve from 1 to 6 seconds from the beginning of the light stimulus (AUC1-6) and D) Area Under the Curve from 1 to 1.7 seconds from the beginning of the light stimulus (AUC1-1.7) both calculated from baseline (100%). Repeated measures ANOVA with Bonferroni post-hoc was performed. ‘c’ indicates significant differences with uncoated control filter (p < 0.05).
