Dusk Nightime Blue Light Blockers

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 by harmonizing the harmful frequencies emitted by artificial lights, which 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 also 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 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, and they are far superior to generic blue-blocking glasses available on the market. Our glasses are engineered to provide the best possible protection against the harmful effects of artificial light, ensuring that you get the restorative sleep you need.

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 unhappiness and dissatisfaction.
• Increased productivity: Better sleep at night can improve your productivity during the day, helping you achieve more and feel more 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, can disrupt your sleep and prevent you from getting the restful sleep you need. By using the right light-blocking technology, you can lower cortisol levels at night, leading to more relaxation and restful sleep.

Investing in high-quality light-blocking technology like VivaRays Nightz glasses can 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 more fulfilling life.

Modern life is filled with artificial light, and unfortunately, many of the devices and light bulbs we use to emit light that can wreak havoc on 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, from the 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 help 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 500nm, which leaves out a significant portion of green light that can still disrupt our sleep. Based on the melatonin suppression zone, there is a 70% melatonin suppression at 500nm and 30% at 550nm 

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 570nm (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 upgrading to Vivarays glasses from generic blue blockers.

In summary, blocking blue and green light up to 560nm 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 colour 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. Clear blue blockers, for example, do not reduce the brightness of light at all. 

Orange glasses typically reduce the brightness by only 2 times, while red-tinted glasses can reduce the brightness by 6 to 8 times. However, many red glasses fail to block 100% of the light frequencies between 400 and 570nm and can allow up to 20% of unwanted light to enter resulting in major melatonin suppression.

Vivarays' Nighttime circadian light harmonizing glasses are an excellent choice for those who want to improve their sleep quality and overall health. They are designed to filter out 100% of blue and green light up to 570nm, which are the exact wavelengths that most affect our internal clock, lower melatonin levels, and alter our sleep/wake cycle. 

These glasses also reduce the brightness by 15 times, making them ideal to be worn 60 to 90 minutes before bedtime, when you are ready to completely relax and prepare your body and mind for a restful night's sleep.

By choosing Vivarays' Nighttime circadian light harmonizing glasses, you can trust that you are getting a high-quality product that will effectively reduce the brightness and filter out harmful light frequencies, allowing you to have a better and more restful sleep.

It's crucial for night-time blue-blocking glasses to eliminate 100% of light leakage, and this is where Vivarays' circadian light-blocking glasses excel. Unlike other red or orange-tinted glasses on the market, which only partially filter out unwanted light frequencies, Vivarays' glasses use a premium lens dye that filters out 100% of the frequencies they're supposed to block.

To better understand why eliminating all light leakage is so important, think of light leakage like 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're designed 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 colour 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.

In conclusion, if you're serious about protecting your sleep, hormones, and circadian rhythms, it's crucial to choose a pair of night-time blue-blocking glasses that eliminate 100% of light leakage. Vivarays' technology achieves this goal through its use of a premium lens dye, state-of-the-art equipment, and rigorous quality control measures, making it the most advanced and effective technology available today.

VivaRays offers two types of glasses that help regulate your body's circadian rhythm and improve your sleep quality:

1.  The Nighttime Circadian Light Harmonizing Glasses: They block all light wavelengths of blue and green light up to 570nm, 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. This is like turning off bright lights and switching to softer ambient lighting, like a dimmed lamp or candles. They are ideal to wear 60 to 90 minutes before bedtime when you are ready to completely relax and prepare for a restful night's sleep.
2. The circadian evening light harmonizing glasses: They block all wavelengths of blue and green light up to 520nm, reducing brightness by 3 to 4 times. They are ideal to wear in the early evening after sunset, enabling you to attend to evening tasks like cooking, socializing, or finishing work without feeling extremely sleepy. The lighter orange tint mimics the colour temperature of fire and candlelight at 1900 kelvins, helping your nervous system and body to start cascading down from peak alertness to rest. These glasses allow for greater colour perception in the evening hours for a more pleasant viewing experience.

To use these glasses in your day-to-day life, switch to the circadian evening light harmonizing glasses after sunset. They'll help you wind down and relax. 

About 60 to 90 minutes before bed, switch to the nightime circadian light harmonizing glasses, also known as the "magic sleeping pill" by our clients, because they maximize melatonin production, making you ready for bed. 

Using these glasses in combination can help your body adjust to the natural light cycle and improve your sleep quality.

Vivarays' circadian night harmonizing glasses are designed to be worn 60 to 90 minutes before bed to increase the production of the sleep hormone melatonin. This technology is so powerful that it is often referred to as a natural sleeping pill, as most people feel sleepy and ready for bed within 30 to 60 minutes of wearing the glasses.

It's important to note that these glasses should never be worn during the day because they block out blue and green light up to 570nm, which are the wavelengths most disruptive to our internal clock and sleep at night. During the day, exposure to these wavelengths is actually beneficial for regulating our sleep/wake cycle, promoting alertness and productivity, and helping us stay energized and awake.

If you use circadian night harmonizing glasses during the day, you will likely feel more tired and sleepy, as you need those frequencies during the day to stay alert and productive. Some people mistakenly use random blue blockers during the day that block too much light, which can have the opposite effect and disrupt their circadian rhythm, energy, hormones, and sleep.

For optimal daytime light harmonization technology that will regulate detrimental artificial light without making you feel sleepy or tired, check out Vivarays' circadian day light harmonizing glasses.

When it comes to blocking blue and green light from affecting our sleep and circadian rhythm, it's important to understand how light behaves and interacts with our eyes. 

Many people are concerned about light entering from the side of their glasses, but rest assured that this is not a significant issue.

To understand why let's look at how light intensity decreases as the angle of incidence decreases.

 When light is shone at a smaller angle, the same amount of light spreads out over a larger area, which makes it less intense. The smaller the angle, the more it spreads out.

 For example, imagine holding a phone or screen directly in front of your eyes. The light is shining on your eyes at a 90-degree angle, which means the light intensity is at its highest and can stimulate the receptors in your eyes, disrupting your circadian clock and sleep.

Now, imagine taking that same phone or screen and rotating it at a 45-degree angle from your eyes. As the angle decreases, the intensity of the light decreases by 2 times. If you position the phone or screen on the side of your eye, the angle at which the light hits the cornea is zero, which means the intensity of the light that arrives at the eye is extremely low.

The same principle applies to light entering from the side of your glasses. While some light may enter from the side, the angle at which it enters is very small, so the intensity of the light is significantly reduced. This means that the light entering from the side is not an issue and will not disrupt your circadian rhythm or sleep.

So, you can wear your non-wraparound circadian glasses with confidence, knowing that they will effectively block blue and green light and improve your sleep quality.

People who work the night shift are more prone to suffering from insomnia, heart attack, depression, metabolic changes, diabetes, obesity, and workplace injuries. The problem worsens when you constantly work on computers or laptops and receive blue and green lights that can damage retinal cells and cause vision issues, macular degeneration, and cataracts. 

Artificial blue and green light can also increase the risk of eye cancer. So, wearing a circadian light harmonizing glasses when working night shifts is essential to preventing these problems and protecting your melatonin levels. Optimal melatonin levels are one of the most significant benefits of wearing Vivarays glasses at the workplace because it is the highest anti-oxidant, an anti-cancerous molecule that the body produces when we stop exposing the eyes to blue and green light 

We recommend you wear the VivaRays Evening light harmonizing lenses during your shift to help you protect your melatonin while staying alert and maintaining optimal physical and mental performance. 

Switch to the VivaRays night light harmonize glasses as soon as you finish your shift and keep them on until you get to bed.

Make sure to blackout the room where you sleep or wear the Vivarays blackout mask

Research shows that blue and green light between 400- 570nm as well as a bright light at night disturbs our body’s natural ability to produce the vital hormones that support our sleep, growth, and rejuvenation such as melatonin and growth hormones.  

Computers, tablets, smartphones, laptops, and light bulbs in the indoor environment emit blue and green light. Therefore, wearing VivaRays blue light glasses that are engineered to protect the eye from shortwave blue &  green frequencies as well as decreasing the brightness by 15 times is essential to: 

• Improving insomnia symptoms 
• Improving sleep quality and duration 
• Restore and enhance circadian rhythm or biological clock 
• Boost cognitive performance 
• Improve memory and learning 
• Strengthens brain function to process information efficiently and quickly 

Wearers of VivaRays sleep glasses report going to sleep faster, and longer, and waking up feeling super refreshed and energized.

Vivarays night circadian light harmonizing glasses are the ultimate solution for anyone suffering from light sensitivity. Designed with cutting-edge technology, these glasses effectively eliminate all the harmful blue and green light emitted from electronic devices and screens and led bulbs.

Chronic exposure to artificial light at night has been scientifically linked to a host of negative effects such as mitochondrial damage, increased inflammation in the eyes, disrupted sleep patterns, and a lack of healing and rejuvenation at night. 

This can result in eye strain, headaches, and a general feeling of light sensitivity.

Also, Chronic exposure to bright light from electronic devices, screens, and LED bulbs, destroys melatonin production, the highest anti-oxidant that cleans the eyes of toxins. This inhibits the the cells in the eye to repair, and cleaning themselves, leading to symptoms of light sensitivity and eye strain the following day.

Many clients who used to suffer from light sensitivity reported

To support a healthy sleep-wake cycle, we suggest wearing our night circadian light filtering glasses once the sun has set and you're exposed to artificial light sources. 

It's very important to keep them on from sunset until bedtime to allow your brain to recognize that it's night-time and start winding down for sleep. This cannot happen in the presence of blue or green light.

Also, Consistency is key when it comes to maintaining a healthy sleep-wake cycle, So make sure to wear them every day, from sunset until bedtime to achieve the best results.

Wearing night-time glasses immediately after sunset can help maximize melatonin release and promote the deepest, most restful sleep.

 However, if you still need to perform tasks after sunset, we recommend our Evening Circadian light harmonizing glasses. These glasses provide less intense light filtering and allow you to be active while still supporting your body's natural sleep-wake cycle.  They are a great option to use in the early evening while cooking dinner, watching TV, or out socializing.

We recommend transitioning to the night circadian light harmonizing glasses one hour before bedtime when you're ready to prepare for a restful night's sleep. Wearing these glasses during this time can help promote deeper sleep and improve sleep quality, leading to feeling more refreshed and energized upon waking.
