Nighttime Circadian light HARMONIZING glasses are a scientifically-engineered technology, designed to mitigate the harmful effects of artificial light at night.

Our glasses offer superior protection, than what already exists on the market, by harmonizing the harmful frequencies emitted by artificial lights,.

These artificial or unnatural lights have been shown to suppress melatonin production and disrupt our circadian rhythm, sleep, and hormones.

Our glasses are designed to block 100% of the frequencies of the blue and green light up to 570nm, ensuring you get a good night's rest and maintain optimal health.

What sets our circadian light-blocking glasses apart from other blue-blocking glasses is their ability to reduce the brightness of light entering your eyes at night, making your body understand that it’s nighttime.

This results in the optimal natural production of the sleep hormone melatonin, which is a powerful anti-aging and anti-inflammatory molecule.

In addition, the reduction of disruptive light frequencies allows for the release of growth hormones, which help our bodies to restore during the night, and enhance our metabolism, and physical and mental performance the following day.

Our circadian light harmonizing glasses are the best option for those who want to improve their sleep quality and overall health.

Wearing nighttime circadian light harmonizing glasses can have significant benefits for your health and well-being. By blocking the wrong type of light at night, you can optimize your circadian rhythm and experience the following benefits:

• More energy and focus: By protecting the production of dopamine, you can wake up feeling motivated and focused in the morning. Artificial light exposure at night can suppress the release of dopamine the following morning, leading to feelings of grief and resentment.
• Increased productivity: Better sleep at night can improve your productivity during the day, helping you achieve more and feel fulfilled
• Improved well-being and inner calm: Artificial light exposure at night can disrupt your natural sleep-wake cycle, leading to feelings of stress and anxiety. By blocking the wrong type of light, you can improve your well-being and experience inner calm.
• Good levels of melatonin and growth hormone for repair and rejuvenation at night: Proper levels of melatonin and growth hormone are crucial for the repair and rejuvenation of the body at night. With the right light-blocking technology, you can ensure that your body is producing these hormones at optimal levels, leading to improved muscle strength, muscle repair, and lean body mass.
• Lower cortisol levels at night for relaxation and restful sleep: High levels of cortisol, the stress hormone, disrupt your sleep and prevent you from the restfulness that your body needs. By using the right light-blocking technology, you can lower cortisol levels at night, leading to more relaxation and rejuvenation.

Investing in high-quality light-blocking technology like VivaRays Night glasses help you achieve all of these benefits and more. With our scientifically engineered lenses, you can rest easy knowing that you are protecting your body and optimizing your circadian rhythm for a healthier, more productive, and fulfilling life.

Modern life is filled with artificial light, which is contrary to natural light that humans are destined to get. And unfortunately, many of the devices and light bulbs we use emit light that can disrupt your sleep and circadian rhythm.

Studies have shown that exposure to blue and green light with a wavelength between 400nm to 570nm confuses your brain into thinking it's daytime and suppresses the production of the sleep hormone melatonin, making it harder for you to fall asleep, stay asleep, and access true deep sleep.

But where does this artificial light come from? It's everywhere in electronics such as screens of our smartphones, TVs, and laptops, to the light bulbs in our homes and public places. Even the light inside our fridge emits blue light, which can disturb our sleep if we're exposed to it at night.

While generic blue-light-blocking glasses on the market only filter out some blue light and no green light, our night-time circadian light harmonizing glasses are specifically designed to provide optimal protection against these harmful frequencies.

They not only block blue and green light up to 570nm but also reduce overall brightness to signal to your body that it's time to wind down and prepare for sleep.

Whether you need to use electronic devices at night or are exposed to artificial light bulbs, our glasses will help you achieve optimal sleep and wake up feeling refreshed, motivated, and ready to take on the day.

It's important for night-time blue-blocking glasses to block blue and green light up to 570nm because blue and green light in this range is known to suppress melatonin production and disrupt our sleep. 

While blue light has been shown to have the maximum impact on our circadian rhythms, research shows that green light can also interfere with our sleep.

For example, a study published in the Journal of Clinical Sleep Medicine in 2019 found that exposure to a green LED device before bedtime delayed the onset of melatonin secretion and reduced the amount of deep sleep in participants

Many blue-blocking glasses on the market partially block blue light up to 500 nm, which leaves out a significant portion of green light that can still disrupt our sleep. Based on the melatonin suppression zone, there is 70% melatonin suppression at 500 nm and 30% at 550 nm. 

This is where Vivarays' night-time circadian light harmonizing glasses stand out. They use a special type of harmonizing pigment that blocks blue and green light up to 570 nm (using a minimum melatonin suppression), while still allowing other beneficial wavelengths of orange and red light to pass through to the maximum possible.

This unique technology ensures that our glasses provide maximum protection against sleep-disrupting light, for optimal melatonin production and better sleep quality. Our clients have reported a profound difference in the quality of their sleep after switching to Vivarays glasses from generic blue blockers.

In summary, blocking blue and green light up to 570 nm is crucial for better sleep, and Vivarays' night-time circadian light harmonizing glasses achieve this with their unique technology, providing the best possible protection against sleep-disrupting light.

The brightness of light has been shown to negatively affect melatonin suppression and sleep quality. Even if the color of light is filtered out, the brightness can still impact our circadian rhythm. That's why reducing the brightness of light is a crucial factor in promoting better sleep.

Many blue light blockers on the market do not reduce the brightness of light, and those that do often fall short.

Vivarays' Nighttime circadian light harmonizing glasses are designed to
reduce the brightness by 15 times, making them ideal to be worn 60 to 90 minutes before bedtime, when you should relax and prepare your body and mind for a restful night's sleep.


By choosing Vivarays' Nighttime circadian light harmonizing glasses, you are sure that you are getting a high-quality product that will effectively reduce the brightness and filter out harmful light frequencies.

To better understand why eliminating all light leakage is essential, think of light leakage as a leaky pipe.
If a pipe has a leak, water will continue to flow through the pipe even if you partially block it. Similarly, if glasses have light leakage, unwanted light will still enter even if some frequencies are filtered out. This leakage of light can negatively affect the quality of your sleep, hormones, and circadian rhythms.

Through testing dozens of orange and red-tinted glasses, Vivarays has discovered that the majority of these glasses have light leakages of 5 to 30% of unwanted frequencies still entering across the whole spectrum. This makes those technologies far less efficient at protecting your sleep, hormones, and circadian rhythms.

The Vivarays Nighttime and Evening Light Harmonizing Lenses, on the other hand, block 100% of all the frequencies they need to block. Vivarays is able to achieve this through its use of a premium lens dye, which has been formulated by a professional laboratory partner over several years of research and development. This dye is the most advanced available today, providing a consistent, uniform harmonizing color that filters out 100% of unwanted light frequencies.

In addition to the advanced lens dye, Vivarays' technology also uses state-of-the-art equipment, skilled workmanship, and rigorous quality control measures on every pair of glasses. This combination of factors ensures that Vivarays' technology is the most advanced and effective circadian light-blocking technology on the market today.

If you're serious about protecting your sleep, hormones, and circadian rhythms, choose a pair of night-time blue-blocking glasses that eliminate 100% of light leakage. Vivarays' technology achieves this goal with the most advanced and effective technology available today.

To ensure your sleep and circadian rhythm are well protected, you should invest in high-quality sleep blue-blocking glasses.

However, not all red-tinted blue light glasses are created equal. There are three key qualities that determine how well they can protect your sleep:

Eliminate 100% of the blue light and green light,
Decrease brightness by 15 to 20 times
Optically optimized lens

After testing dozens of red-tinted blue-blocking glasses on the market, we found that very few of them were meeting those 3 qualities simultaneously.

While companies like Ra-optics, Boncharge, and Block Blue Light offer good quality red-tinted glasses, our tests show that they block 95% of the light up to 550 nm, and only decrease brightness by 4-6 times.

It’s also fair to say that most other red-tinted glasses offer a much lower quality product compared to the 3 companies mentioned above, which are considered premium.

Our VivaRays Nighttime circadian light harmonizing glasses are scientifically engineered by experts to provide superior protection to your sleep and circadian rhythm. They are designed to block 100% of blue and green light up to 570 nm, which is the zone where melatonin is disrupted by light, and decrease the brightness by 15-20 times. Additionally, all our lenses are optically optimized to ensure clear vision. This combination of features makes our glasses the most efficient on the market for protecting your sleep and circadian rhythm.

Once you experience the benefits of our glasses, we know you'll agree that they are, by far, the best choice.

The Nightime circadian light harmonizing glasses block all light wavelengths of blue and green light up to 570 nm, which are the most damaging to melatonin production and sleep. These glasses also reduce the brightness by 15 times, as research has shown that brightness affects melatonin suppression and can negatively impact sleep.

On the other hand, cheap blue-blocking glasses from Amazon do not have the same level of technology and are often generic, with no specific focus on blocking the correct harmful blue and green light frequencies. These glasses have light leakages of 5 to 30% of unwanted frequencies still entering across the whole spectrum. This makes those technologies far less efficient at protecting your sleep, hormones, and circadian rhythms.

Additionally, cheap blue-blocking glasses from Amazon are not made with the same quality and ethically sourced materials, which can lead to discomfort and durability issues. Vivarays glasses are designed with quality materials, ensuring both comfort and long-lasting wear.

Lastly, at Vivarays, we use eco-friendly and ethically sourced materials which sets us apart from other cheap blue-blocking glasses present on the market, mostly Amazon.

With Vivarays, you can not only protect your sleep, hormones, and circadian rhythm from harmful blue light but also do your part in taking care of the planet.

VivaRays offers two types of glasses designed to regulate your body's circadian rhythm and enhance sleep quality. 

Circadian Evening Light Harmonizing Glasses: These glasses block 100% of blue and some green light up to 520nm, dimming brightness by 3 to 4 times. They are perfect for wearing in the early evening after sunset, allowing you to carry out tasks like cooking, socializing, or working without feeling excessively drowsy.

 The glasses' patented orange tint resembles the warm glow of fire or candlelight at 1900 kelvins. Picture yourself near a bonfire: you feel calm and relaxed, yet energetic enough to dance, cook, and socialize. 

The evening lenses facilitate a gradual transition from peak alertness to relaxation while maintaining better color perception for a pleasant viewing experience.

Nighttime Circadian Light Harmonizing Glasses: These glasses block 100% of blue and green light up to 560nm, the most disruptive wavelengths for melatonin production and sleep. They also reduce the brightness by 15 times, as excessive brightness can suppress melatonin and negatively affect sleep. 

The deep red patented tint mimics the color temperature of the end of a bonfire at 1200K when the wood turns into glowing embers. Imagine how drowsy and ready for bed you would feel at this point. Wear these glasses 60 to 90 minutes before bedtime to fully unwind and prepare for a restorative night's sleep.

To effectively use these glasses in your daily routine, wear the Evening Glasses after sunset to help you unwind and relax. Then, switch to the Nighttime Glasses, also known as the "magic sleeping pill" by clients, 60 to 90 minutes before bed to maximize melatonin production and prime your body for sleep.

By using both types of glasses in combination, you can help your body adapt to the natural light cycle and enhance sleep quality. Remember, it's not about choosing one over the other; both technologies work together for optimal results.
