    The AYO Circadian Rhythm Glasses can be used with or without the support of the AYO app, and are ideal to:

    • Assist shift workers transition between sleep/wake routines
    • Increase energy or overcome daytime fatigue
    • Minimise jetlag symptoms by aligning circadian rhythm with destination time zone during the flight
    • Improve sleep quality.

    The AYO app provides users guidance with:

    • User’s personal circadian rhythm and its unique stages during the day-night cycle
    • Personal recommendations for each specific stage regarding light, food, coffee, cognition, exercise and sleep
    • When to use the AYO to achieve your wake-up goal.

    Using proprietary algorithms and latest science, the AYO app calculates and provides users with their personal Circadian Health. Users can learn how in sync they are with their circadian rhythm – a biological foundation affecting most of the brain and body processes from sleep, alertness, metabolism and immune response. 

    Can it be worn with prescription glasses?

    AYO is designed to be able to be used with the most common prescription glasses' frames. The AYO wearable has a flexible nosepiece, which can be adjusted to allow an easier positioning of both the prescription glasses and the wearable. By bending the nosepiece horizontally, AYO becomes more like a frame, which can be put on top of the prescription glasses. For an optimal experience and whenever possible, we recommend using AYO glasses without prescription glasses as the glasses can interfere with the light diffusion of AYO glasses. If you use prescription glasses with a blue-light blocking filter, ensure that the filter is not blocking blue-turquoise light of 470 nm of wavelength since the light from AYO glasses will not be efficient. 

    How does this work? Is it worn in the mornings only? 

    The recommended usage is one or two 20-min sessions in the morning upon waking up. However, it depends on the desired effect (i.e. adjusting sleep-wake cycle, boosting energy, improving sleep, alleviating jet lag, etc.). In the AYO manual it offers recomendations as to when it shoudl be used for different requirements.  it , which you can find inside the package, is explained the usage for several use cases. 

    What is Light Therapy

    Light therapy, sometimes called phototherapy, or bright light therapy, is the use of light to treat a broad range of health and medical conditions. Light therapy glasses are portable devices worn while you get dressed, have breakfast, work out or even have an early morning conference call instead of being anchored in your chair during therapy. But it may ease symptoms, increase your energy levels, and help you feel better. 

    Sleep/circadian problems you can treat with light therapy

    Circadian rhythm is the biological clock that regulates several physiological functions of the body, including the sleep-wake cycle, immunity, hormone secretion, and temperature. 

    Light therapy’s impact on the body clock lends itself to a range of conditions broadly concerned with circadian health. Here’s a quick rundown:


    Difficulty falling asleep at night can occur for numerous reasons. If you’ve been diagnosed with chronic insomnia you should seek qualified medical advice and appropriate treatment like CBTi.  

    Difficulty waking up

    Waking up, especially when it’s still dark outside, can be difficult to cope with if you’re not a natural early riser.  Using AYO bright light in the morning helps your body adapt to being awake.


    Travelling across time zones causes your sleep/wake schedules to be completely out of whack with your body clock. Whether it’s for work, or even a leisure break, you want to feel energised and at your best when you reach your destination. 


    Shift workers, and especially nightshift workers, face enormous challenges in adapting their body clock to fit work schedules that often change, rotate and turn day into night. 

    Energy boost
    If you work in a dimly lit environment, or you’re generally tired during the day, light therapy glasses are an ideal, safe way to give you a direct energy boost when having an afternoon slump because they simulate the natural invigorating effects of being in bright sunlight.
