Humans live in a 24-hour environment, in which light and darkness follow a diurnal pattern.
Our circadian pacemaker, the suprachiasmatic nuclei (SCN) in the hypothalamus, is …

The mammalian visual system encodes information over a remarkable breadth of
spatiotemporal scales and light intensities. This performance originates with its complement …

Ocular light drives a range of nonvisual responses in humans including suppression of
melatonin secretion and circadian phase resetting. These responses are driven by …

This paper discusses the rise of human-centric lighting and its current status in lighting. We
summarise the human benefits associated with light and lighting and show that human …

At its best, human-centric lighting considers the visual and non-visual effects of light in
support of positive human outcomes. At its worst, it is a marketing phrase used to …

Light profoundly affects our mental and physical health. In particular, light, when not
delivered at the appropriate time, may have detrimental effects. In mammals, light is …

Introduction Light elicits a range of non‐visual responses in humans. Driven predominantly
by intrinsically photosensitive retinal ganglion cells (ipRGCs), but also by rods and/or cones …

Light is known to elicit non–image-forming responses, such as effects on alertness. This has
been reported especially during light exposure at night. Nighttime results might not be …

Twilight is characterised by changes in both quantity (“irradiance”) and quality (“colour”) of
light. Animals use the variation in irradiance to adjust their internal circadian clocks, aligning …

Light‐induced melatonin suppression data from 29 peer‐reviewed publications was
analysed by means of a machine‐learning approach to establish which light exposure …
