AYO Light Therapy Glasses – Light Therapy for Energy, Focus, and Sleep Optimization
AYO Light Therapy Glasses is an innovative and clinically proven light therapy device that uses blue-turquoise light to balance the body’s circadian rhythm – your internal biological clock that regulates energy, sleep, mood, and hormonal balance.
By mimicking the natural spectrum of sunlight, AYO helps you boost energy and alertness during the day while enhancing the body’s natural melatonin production at night for deeper and more restorative sleep.
Unlike energy drinks, caffeine, or supplements, AYO works naturally through light’s physiological impact on the body’s cells – a true biohack for those seeking to optimize health, performance, and overall well-being.
Scientifically Proven Effect
AYO Light Therapy Glasses are based on the scientific discipline of chronobiology – the study of how light influences the body’s internal rhythms.
Independent clinical studies from institutions such as the University of Reykjavik and the U.S. Department of Defensehave shown that AYO can:
-
Improve sleep quality and reduce sleep-onset difficulties
-
Increase energy and concentration
-
Strengthen circadian rhythm during jet lag or shift work
-
Counteract winter fatigue and seasonal affective disorder
AYO light has also been shown to enhance recovery, performance, and mental clarity – making it an advanced yet easy-to-use tool for modern humans who want to live in sync with their biology.
How AYO Works
AYO emits a specific blue-turquoise light at approximately 470 nm, matching the most active part of the daylight spectrum.
This light suppresses the production of melatonin during the day, boosting energy, focus, and alertness – while helping the body naturally produce more melatonin at night, improving sleep quality and duration.
Each session lasts about 20 minutes, with a light intensity equivalent to 10,000 lux from a traditional light therapy lamp. The light is certified safe according to international photobiological standards (IEC 62471) and TÜV Rheinland certified.

How to Use
Use AYO Light Therapy Glasses with your eyes open, as the light needs to reach your eye receptors to be effective.
The optimal time to use AYO is in the morning to reset your circadian rhythm and increase energy, though timing can vary depending on your lifestyle, travel schedule, or work shifts.
The AYO app provides personalized recommendations on when and how long to use the light, and when to avoid it for maximum results. The app is optional – AYO works perfectly on its own – but offers an added layer of precision and guidance for those who wish to optimize their light therapy.
AYO can be worn while performing everyday tasks – working at your computer, preparing breakfast, or reading – thanks to its lightweight and open design.
Design and Comfort
AYO is the lightest light therapy device on the market, weighing only 30 grams.
Its sleek design allows you to wear it with or without glasses – it simply rests above your frames, with a flexible nosepiece that adjusts for a perfect fit.
Unlike traditional light boxes that require you to sit still in front of a lamp, AYO is portable, wireless, and discreet, making it easy to integrate into your daily routine.
Safety and Certifications
AYO’s light is rigorously tested and certified as safe for the eyes, meeting these standards:
-
IEC 62471 (EU standard for photobiological safety)
-
TÜV Rheinland certification
-
ISO 15004-2 (eye safety)
-
ANSI Z80.36
The wavelength is optimized for maximum effect and comfort, with no UV radiation or risk of eye or skin damage.
Possible Side Effects
As with all light therapy, mild reactions may occur initially, such as temporary headaches, eye strain, or mild discomfort.
These are rare, short-lived, and usually subside if you lower the intensity or shorten the session duration.

FAQ – Everything You Need to Know About AYO Light Therapy Glasses
1. How do AYO Light Therapy Glasses work?
AYO Light Therapy Glasses uses blue-turquoise light at around 470 nm – the most active wavelength of daylight.
The light stimulates photoreceptors in the eyes that influence the brain’s production of melatonin and cortisol.
The result: increased energy and focus during the day and improved sleep quality at night. It’s a natural biohack for restoring the body’s internal clock (circadian rhythm).
2. How often and when should I use AYO Light Therapy Glasses?
The recommended use is one 20-minute session per day, preferably in the morning to signal “daytime” to your body.
For jet lag, shift work, or winter fatigue, the AYO app can provide personalized timing recommendations based on your circadian rhythm.
You can wear the glasses while working, reading, or having breakfast.
3. Is AYO’s light safe for the eyes?
Yes. The light is classified as eye-safe under international standards such as IEC 62471 and ISO 15004-2, and AYO is TÜV Rheinland-certified.
The light contains no UV radiation and causes no damage to eyes or skin.
Mild effects such as temporary eye strain or headache are rare and can be managed by reducing exposure time.
4. What results can I expect from using AYO?
Many users notice increased energy, sharper focus, and easier morning wake-ups after just a few days.
Within 1–2 weeks, improvements in sleep quality and circadian balance are often reported.
AYO is also widely used by travelers, athletes, and shift workers to quickly recover from jet lag and reduce fatigue.
5. Can I use AYO Light Therapy Glasses if I wear glasses or contact lenses?
Absolutely. AYO Light Therapy Glasses is designed for maximum comfort and can be worn on top of regular glasses or contact lenses, thanks to its flexible nosepiece and ultralight design (only 30 g).
The open design allows natural light to pass through, so you can continue with daily activities during your session.
