Visible light synchronizes the human biological clock in the suprachiasmatic nuclei of the
hypothalamus to the solar 24‐hour cycle. Short wavelengths, perceived as blue color, are …

Artificial light at night (ALAN) is increasing exponentially worldwide, accelerated by the
transition to new efficient lighting technologies. However, ALAN and resulting light pollution …

Well-being in the built environment is a topic that features frequently in building standards
and certification schemes, in scholarly articles and in the general press. However, despite …

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

Daylight stems solely from direct, scattered and reflected sunlight, and undergoes dynamic
changes in irradiance and spectral power composition due to latitude, time of day, time of …

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

Light enables vision and exerts widespread effects on physiology and behavior, including
regulating circadian rhythms, sleep, hormone synthesis, affective state, and cognitive …

Purpose Despite extensive research, mechanisms regulating postnatal eye growth and
those responsible for ametropias are poorly understood. With the marked recent increases …

The use of artificial lighting to illuminate the night has provided substantial benefits to
humankind. It has also disrupted natural daily, seasonal, and lunar light cycles as …

Light around twilight provides the primary entrainment signal for circadian rhythms. Here we
review the mechanisms and responses of the mouse and human circadian systems to light …
