The past decades have generated compelling laboratory evidence showing that light exposure profoundly impacts on human circadian physiology through a pathway connecting a subset of ganglion cells in the retina to the hypothalamus. While these laboratory studies generally demonstrate the biological capacity of non-visual photoreceptive pathways to respond to light, the significance and relevance of light exposure in the real world does not immediately follow from "biological capacity" studies. One key component for understanding the impact of light exposure in the real world is measuring patterns of light exposure. In the past years, wearable light loggers have become available to accomplish this task. In this webinar hosted by the Color Technical Group, Manuel Spitschan will review new developments in this area and discuss challenges and research gaps that need to be addressed.
