50.1: Invited Paper: The Importance of Melanopsin Activation in Perception, Health, and Lighting Design.

We reviewed the role of melanopsin-containing intrinsically photosensitive retinal ganglion cells (ipRGCs) in light-dependent functions, including circadian rhythm that is important for health, pupil responses and visual perception. We then discussed the implications for lighting design. Finally we described a five-primary photostimulating method that can independently control melanopsin activation in humans.
