Light therapy glasses vs light boxes and lamps Hence, by controlling the amount of light we’re exposed to at certain times of the day, we can push the ‘reset’ button on our internal clock, helping our circadian rhythms revert back to a ‘natural’ timing whereby you’ll feel suitably energized in the day, and sleepy at night. Blue light or green light in the morning helps to stimulate both the production of cortisol (you can think of this as a ‘wake up’ hormone), but also these wavelengths also block the production of melatonin – the hormone we produce during the night to facilitate restful sleep.

These cells had nothing to do with vision but instead they absorbed light as a means to synchronise our internal body clocks.īecause we’ve evolved over millions of years to sleep and wake with the natural cycle of day and night, any disruption to the light/dark cycle can cause not just sleep problems, but also impact our daytime energy levels, moods, concentration, and productivity as a whole. The technology behind Pegasi is derived from 10 years of research conducted by Johns Hopkins University School of Medicine where scientists discovered a new type of light-sensitive cell in our eyes. Launched via a successful Kickstarter campaign in the summer of 2018, the new light therapy glasses have better ergonomics, battery life and more tweaks that we’ll talk about later.īut before we talk about the product itself, let’s find out what these smart glasses could do for your sleep? How can a pair of glasses help you sleep better? The company had just launched their first generation of smart sleep glasses, a simple, easy to use light-therapy product designed to help users sleep better at night, increase energy throughout the day and combat issues caused by disrupted sleep schedules such as shift working and jet lag.Īfter success with the first generation product, Pegasi are back with Smart Sleep Glasses II. I first heard about Chinese health-tech firm Pegasi via the inaugural Sleep Technology showcase at CES 2017, the world’s largest gadget-showcase of consumer electronics.
