Color

The Color Technical Group works on all aspects related to the physics, physiology, and psychology of color in biological and machine vision, including, but not limited to, color discrimination, color perception and color appearance; color rendering, color in lighting and illumination engineering; standardization of the human cone and rod fundamentals; photometric quantities related to cones, rods, and melanopsin; and color properties of emerging display and lighting technologies.
 

"Blue" Light and Its Effect on Circadian Rhythms, Sleep, Alertness and Cognition

When: 8 April 2020, 12:00 - 13:00

This webinar, hosted by the OSA Color Technical Group, will focus on the effect of light on aspects related to circadian rhythms and sleep, a topic that has received a lot of media attention in the past years.

Starting from the fundamental findings, Christian Cajochen from the Centre for Chronobiology, Psychiatric Hospital of the University of Basel will discuss our current state of knowledge on how short-wavelength, or "blue" light, specifically can impact circadian rhythms and sleep. The webinar will be focused on empirical evidence and placing it into the context of interventions in the home and office environment.

What You Will Learn:

  • Fundamentals in the non-visual effects of light, such as melatonin suppression and circadian phase shifting
  • Experimental methods and protocols to address non-visual effects of light
  • Optimizing the lighting environment to minimize circadian disruption

Who Should Attend:

  • Scientists and professionals interested in the effect of light "beyond vision"
  • Lighting designers and engineers

About the Presenter: Christian Cajochen, Centre for Chronobiology, Psychiatric Hospital of the University of Basel

Prof. Christian Cajochen is heading the Centre for Chronobiology at the University of Basel. He received his PhD in natural sciences from the ETH in Zürich, Switzerland, followed by a 3-y postdoctoral stay at the Harvard Medical School in Boston, USA. His major research interests include investigative work on the influence of light on human cognition, circadian rhythms and sleep, circadian related disturbances in psychiatric disorders, and age-related changes in the circadian regulation of sleep and neurobehavioral performance. He has held a number of honours and has authored more than 150 original papers and reviews in his career.
