Fig. 2From: Impact of blue-depleted white light on pupil dynamics, melatonin suppression and subjective alertness following real-world light exposureA representative tracing of pupil area as it changes in response to a sixty-second light exposure that is preceded and followed by darkness. In each exposure, we quantitate the baseline in darkness, the peak constriction, the sustained constriction, and the PIPR starting 6 s after the cessation of the lightBack to article page
