Our perception of the world is so dominated by our sense of vision that we have been reluctant to accept the fact that the vertebrate eye mediates another, quite separate photosensory task—the detection of light for the regulation of biological time. In this short article, we outline some of the recent experimental findings that show that the absence of rod and cone photoreceptors does not block the effects of light on the circadian system. Furthermore, we review the progress to date in identifying the photopigments that may mediate the effects of light on the mammalian biological clock.
