    Circadian Glasses

    Your body runs on rhythm. Every single cell, every organ, and every hormone follows a natural 24-hour cycle called the circadian rhythm. It tells you when to wake up, when to eat, and when to rest.

    But modern life has changed the way we experience light and darkness. We spend most of our time indoors, surrounded by screens and artificial lighting that trick our brains into thinking it's daytime even long after the sun has set. Over time, that constant light exposure can throw your rhythm off, affecting your sleep, focus, and overall energy.

    VivaRays Circadian Glasses are designed to bring your body back into sync with nature’s light-dark cycle. Through carefully engineered lens technology, these glasses guide your eyes and brain through the right light signals at the right times of day. The result is deeper sleep, steadier energy, and sharper focus, all without depending on caffeine or supplements.


    The Science Behind Circadian Light


    At the center of your brain lies a tiny region called the suprachiasmatic nucleus, or SCN — your body’s master clock. This clock runs on one simple truth:

    It needs natural light during the day and darkness at night to stay in rhythm.

    When your eyes receive the full spectrum of sunlight (especially blue and green light between 450 and 570 nanometers), your brain knows it’s daytime. Cortisol rises, melatonin stays low, and you feel alert, focused, and energized.

    But when that same light from screens or lamps hits your eyes after sunset, your brain gets confused. It still thinks it’s day, keeping cortisol high and melatonin low, leaving you wired, anxious, and unable to rest.

    Over time, this mismatch between your environment and your biology can cause fatigue, poor sleep quality, and even mood and metabolic issues.

    That’s why VivaRays exists. Our lens system restores this lost balance, giving your brain the right light signals at the right time, so your hormones, mood, and sleep can return to their natural rhythm.


    How VivaRays Circadian Glasses Work


    Daytime Lenses

    These lenses are designed for the productive part of your day. VivaRays Daytime Lenses don’t block blue light; they balance it. By softening the harsh, high-intensity blue from screens and daylight, they help reduce eye strain while keeping you alert and focused.


    Sunset Lenses

    As the day winds down, your body needs a gradual shift toward rest. The VivaRays evening lenses help ease that transition by filtering 100% of blue light and the more stimulating green wavelengths. The light you see through them feels warm and soft, similar to the glow of a bonfire, allowing your mind to relax while still seeing clearly in indoor lighting.


    Sleep / Red Lenses

    When it’s time to fully disconnect, VivaRays Nighttime red lenses block 100% of blue and green light (up to ~560 nm) and reduce brightness dramatically (~15×). They turn your world into a firelight amber, signaling your body that night has come, allowing melatonin to flow naturally and guiding you into restful, restorative sleep.


    Benefits of Aligning with Your Natural Rhythm


    1. Better Sleep and Recovery
      By allowing melatonin to rise naturally in the evening, circadian glasses help you fall asleep faster and wake up feeling truly rested. Quality sleep improves your mood, memory, and immune health.
    2. More Consistent Energy Levels When your light exposure matches your biological needs, your body naturally regulates cortisol and other hormones linked to alertness. That means steady, sustainable energy throughout the day rather than highs and crashes.
    3. Sharper Focus and Mental Clarity Proper light exposure enhances neurotransmitter balance and supports better cognitive performance. You’ll notice improved focus and fewer afternoon slumps when your eyes and brain are in sync with your circadian rhythm.
    4. Reduced Eye Strain and Fatigue Filtering the most intense light wavelengths minimizes glare and tension from screens or artificial lighting, allowing you to work and unwind comfortably.
    5. Long-Term Health Support
      Maintaining a healthy circadian rhythm influences everything from metabolism to mood regulation. It’s one of the simplest, most natural ways to support your body’s long-term wellness.

    Designed for Every Lifestyle


    VivaRays offers circadian lens systems that move with you through the day. Each set includes multiple lenses that can be used individually or as clip-ons, allowing you to use them seamlessly from morning to night. Frames are made from lightweight, high-quality sustainable materials and fitted with high-precision optics that maintain clarity while delivering optimal wavelength control.

    You can choose from:

    • Daytime circadian glasses for bright environments and screen-heavy work.
    • Evening lenses for winding down without disrupting your rhythm.
    • Full circadian systems with interchangeable lenses for round-the-clock balance.

    Every pair undergoes optical testing to ensure wavelength accuracy and consistent results across different lighting conditions.


    How to Use Them for Maximum Benefit


    • Wear daytime lenses during sunlight hours, anytime you are indoors under artificial light, or in front of screens.
    • Switch to evening lenses around sunset or when indoor lights come on.
    • Use red/nighttime lenses one to two hours before sleep to fully block blue and green light.
    • In the morning, expose yourself to real sunlight for 10–15 minutes to reinforce your circadian rhythm naturally.

    These simple habits, combined with the right lens support, can transform how you sleep, think, and feel each day.


    Reconnect with Your Natural Rhythm


    VivaRays is your way back home. Your body already knows how to sleep deeply, wake up energized, and move through the day with ease and clarity. It’s been doing this for millions of years.

    You were never broken. You were simply living in the wrong light.

    VivaRays recreates the environment your body was designed for, giving you the right light signals at the right times, so you can finally live in sync with your biology, not against it.

    Deep sleep. Steady energy. Mental clarity. Balanced mood.

    This is what it feels like to come home to your natural rhythm.

    Frequently Asked Questions

    VivaRays glasses are designed to support your circadian rhythm, not just block blue light. Each lens type (daytime, evening, and nighttime) filters light in a way that mimics natural sunlight throughout the day, helping your body maintain its natural sleep–wake cycle and overall energy balance.

    Use Daytime lenses during daylight hours, especially indoors or around screens. Switch to Evening lenses around sunset or when indoor lights come on. Before bed, wear Nighttime red lenses to block all blue and green light for deeper, more restorative sleep.

    Yes! Even if you get natural sunlight, artificial lighting from screens and indoor bulbs can still disrupt your circadian rhythm. VivaRays lenses help you stay in sync when you’re inside or exposed to bright lights after sunset.

    Absolutely. By blocking disruptive wavelengths of light in the evening and allowing melatonin to rise naturally, VivaRays glasses help improve sleep quality, reduce nighttime restlessness, and make it easier to fall asleep faster and wake up refreshed.

    Yes. VivaRays offers clip-on and interchangeable lens systems that can be worn over most prescription glasses, or you can order frames fitted with your own prescription lenses for complete comfort and visual clarity.
