Colloquium ACP: Light Spectra, Circadian Rhythm and Performance
- Tobias Borra
- Monday 31 October 2016
2333 AK LEIDEN
Dr. Tobias Borra studied Cognitive Psychology at Leiden University, after which he did his PhD in psychophysics at Utrecht University, specialising in fundamental visual processing. After two post-docs (Physics and Astronomy in Utrecht, and Experimental Psychology in Utrecht) he worked two years for a User Experience research company, after which he started at Philips Lighting. Currently he does fundamental research into the perception of light, (psychological) effects of light and spectral aspects of light.
Light Spectra, Circadian Rhythm and Performance
A quick search through the literature immediately shows an abundance of evidence for visual effects of light. However, relatively recently it was discovered that the human retina also contains cells that are responsible for non-visual effects of light. This knowledge, combined with a recent transition of ‘traditional’ lighting (e.g. incandescent, fluorescent and halogen) to LED lighting, allows for a whole range of opportunities to optimally support human performance.
