The study found that “while blue-light is usually the most effective way to stimulate the non-visual responses – especially under bright light conditions- stimulation with green light was also capable of eliciting the non-visual responses under certain circumstances.”Įssentially, the research showed that green light activated both the visual receptors (rods and cones) and the non-visual receptors in the eyes. So I contacted Renny at Pegasi who directed me to a 2010 study from the Journal of Science and Translational Medicine Pegasi Smart Glasses II with green wavelength LEDs Initially I was puzzled why the LEDs weren’t blue or white as this is regarded as the most effective hue to influence melatonin production. Pegasi Smart Glasses II emit light wavelengths in the green spectrum. Whilst definitely not a replacement for clinical bright light therapy, Pegasi’s smart glasses are designed to give you some of the benefits of using a light box, but you’re able to walk around and do all your normal activities (except perhaps taking a shower…), making the breakfast, checking your emails, without having to interrupt your daily activities.

Light therapy is a common treatment for seasonal affective disorder (S.A.D.), a mood disorder that occurs in the winter months when the levels of sunlight are much lower.īut the standard treatment for S.A.D., as well as other circadian rhythm sleep disorders, is by using a light box – an extremely bright standalone full spectrum light which you sit in front of. 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.Ĭertain wavelengths (colours) of light have different effects on us at different times of the days. 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 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. Alternatives to Pegasi Smart Sleep Glasses II Introduction
