FIGURE 5.

Melatonin suppression for different combinations of exposure duration and melanopic EDI as predicted by the logistic dose‐response model (Equation 7) for an undilated pupils scenario. The coloured lines represent the profiles of three levels of melatonin suppression. The coloured areas indicate ranges of melanopic EDI that are recommended for practicular application contexts: ideal sleep environment (grey area), sleep supportive evening setting at home (cyan area) and daytime indoor environment (yellow area). The dashed grey line indicates the profile of 50% melatonin suppression under a dilated pupils condition, it is shifted to the left as compared to the undilated pupils scenario, which signifies a higher sensitivity.
