Pegasi Smart Glasses II is a pair of lensless glasses that uses light therapy to improve the sleep quality of the user. but do they work? This review will answer that question.
Here’s the problem:
Sleeping problems are one of the main factors that affect general quality of life. Poor sleeping schedule, working in shifts, and jet-lag could cause some trouble with your biological clock and thus affect our sleep quality.
Using Pegasi for just 30 minutes a day for seven days, you can solve sleeping problems and improve your sleep quality. Plus, the new hinged collapsible frame allows easier use, making it simple to carry Pegasi anywhere.
In a hurry? Here’s a quick summary of this:
How Can Pegasi glasses Improve Your Sleep?
The technology behind these glasses is based on the Johns Hopkins University School of Medicine research that lasted some ten years.
In this research, scientists found out that our eyes contain light-sensitive cells.
These cells don’t have anything to do with our vision; instead, they absorb light so they can synchronize our internal body clocks.
Throughout millions of years, our sleep cycle has evolved to follow the natural period of night and day. Because of this, any disturbance to the dark/light cycle can cause sleep problems. It can also have a significant impact on our energy levels, concentration, moods, and productivity in general.
Particular wavelengths (colors) of light at certain times of the day affect us differently. Greenlight or blue in the morning at the same time promotes cortisol production and blocks the production of melatonin. To further explain, melatonin is a hormone that is produced during the night to enable restful sleep, and you can think of cortisol as a ‘wake up’ hormone.
So we can change that?
It seems, we can push the ‘reset’ button on our internal clock by handling the volume of light that we’re exposed to at particular times during the day. This way, we help our circadian rhythms to return to our ‘natural’ timing. As a result, you’ll feel sleepy during nighttime and have plenty of energy during the day.
Why choose Light Therapy Glasses Over Lightboxes?
Seasonal affective disorder (SAD) is usually treated with light therapy; this is a mood disorder that often happens to people during winter when the sunlight levels are lower.
But the regular treatment for SAD and any other sleep disorders involving circadian rhythms is to use a lightbox. This is an exceptionally bright light that you put in front of you, and it shines in your face.
Pegasi smart glasses are not a substitution for bright light therapy, but they are made to provide you with some of the advantages of a lightbox. The only difference is that you’re not fixated into one place, so you can do your routine activities, make breakfast, check your emails (except maybe take a shower).
The Difference Between Green and Blue Light
These light therapy glasses emit wavelengths in the form of light in the green spectrum.
The question of why green instead of blue comes from the fact that blue and white are thought to be the most effective hues to affect melatonin production.
And to answer this, we need to refer to a 2010 study from the Journal of Science and Translational Medicine.
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.”
The research proved that the green light activates both the visual and the non-visual receptors in our eyes. Throughout the testing, for short periods of light exposure, and light sources of low brightness, the green and blue light are equally efficient at defeating melatonin.
The study concludes by stating that “light therapy for sleep disorders and other indications might be optimized by stimulating both photoreceptor systems.”
How easy are they to use though?
How to Use the Pegasi Glasses
Pegasi markets their glasses as ‘smart eyewear,’ but they are straightforward to use. They come with an app, which you’re not obligated to use (more on this later).
- Just put the glasses on when you wake up – the recommended time is between 7 and 9 am.
- Switch them on, the glasses will emit light for 30 minutes, after which they will turn themselves off.
- Sleep experts recommend waking up with bright lights or with the sun, if possible. So, an excellent way to get your sleep into regulation is to start your day off with 30-minute sessions with Pegasi.
It might seem that the glasses would be intrusive, but this is not the case, although the light is directly above your eyes. They’re ergonomically-designed, but unless you intentionally look up into the glasses, the LED’s never become distracting.
The company says their glasses are appropriate for almost any situation, except for driving, and any other tasks where your unobstructed vision is required. The product is also not to be used by children younger than 13.
Pegasi says if you stick to the recommended usage of the product, the changes in how you sleep should be noticeable within seven days. Besides wearing them in the morning, you can also wear the glasses at any time for a quick energy boost.
The battery proved to be outstanding; it takes only 70 minutes to charge fully. One charge can last you up to two weeks since you’re supposed to only wear them for 30 minutes a day.
Essentially, this is a ‘dumb’ smart product, meaning that it’s easy to use and your only job is to make sure it’s fully charged, and turn it on.
If you want to delve deeper into the technology behind Pegasi, the app named Pegasi Sleep is available to you, and you can get it both for Android and iOS. Through the app, you can connect with Pegasi glasses via Bluetooth; this way, you can check the battery, as well as set the protocol.
Protocols control the lights’ level of brightness and the duration for which the LED’s stay on. There are three protocols to choose from:
The Mild protocol lasts some 40 minutes and it’s a dimmer light setting.
It’s recommended for people sensitive to bright light. The Standard, or default mode is a 30-minute duration at standard brightness. And the Strong protocol gives you 20 minutes, but at full intensity.
Pegasi smart sleep glasses price and summary
Overall, we like the Pegasi Smart Glasses II. They are straightforward to use, and they let you go about your daily tasks without any interruptions. The price for these is around $100-200 depending on where you buy them and where you live.
If you’re in the market for a high-quality, low maintenance product that lets you reap the benefits of light therapy, this product is worth a try.
