Light exposure protocol during the chromatic pupillometry procedure. Participants were exposed to two minutes of logarithmically increasing intensity of blue light followed by exposure to red light and pupillary responses to both lights were recorded in each subject. Each exposure to light was preceded and followed by one minute of darkness. There was a gap of up to one minute of darkness between the blue and red light exposures.
