Robert Casper MD

Dr Robert Casper (Senior Investigator at the Samuel Lunenfeld Research Institute and the Camille Dan Family Research Chair in Translational Cell Biology) developed special lenses that filter out the harmful light wavelengths that interfere with the body’s natural circadian rhythms. Now, new results from a pilot project at Toronto Western Hospital with night-shift nurses, and among night-shift workers at the Bruce Nuclear Power Plant in Kincardine have shown that wearing the lenses suppressed hormone disruptions and improved alertness, performance and mood during simulated shift work. According to Dr Casper, use of the lenses also shortened the time needed to fall asleep and resulted in significant improvements in the quality of sleep.
