The NightTime glasses are a scientifically designed technology to mitigate the harmful effects of artificial nighttime light.

Our glasses offer superior protection compared to what already exists on the market by harmonizing the harmful frequencies emitted by artificial light sources. It has been demonstrated that these artificial lights suppress melatonin production and disrupt our circadian rhythm, sleep, and hormones.

Our glasses are designed to block 100% of blue and green light up to 540 nm, and 95% of the green wavelength between 540 nm and 570 nm, ensuring good nighttime rest and optimal health.

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

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

Additionally, the reduction of disruptive light frequencies allows for the release of growth hormone, which helps our body recover during the night and improves our metabolism and physical and mental performance the following day.

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

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

More energy and focus: By protecting dopamine production, you can wake up motivated and focused in the morning. Exposure to artificial light at night can suppress dopamine release the next morning, leading to feelings of pain and resentment.

Higher productivity: Sleeping better at night can improve your productivity during the day, helping you accomplish more and feel fulfilled.

Greater well-being and inner calm: Exposure to artificial light during the night can disrupt the natural sleep-wake cycle, leading to stress and anxiety. By blocking the wrong type of light, you can improve your well-being and experience inner calm.

Healthy melatonin and growth hormone levels for nighttime repair and rejuvenation: Adequate levels of melatonin and growth hormone are crucial for the body’s repair and rejuvenation during the night. With the proper light-blocking technology, you can ensure that your body produces these hormones at optimal levels, resulting in greater muscle strength, muscle repair, and lean body mass.

Lower nighttime cortisol levels for greater relaxation and restorative sleep: High levels of cortisol, the stress hormone, disrupt sleep and prevent the rest the body needs. By using the proper light-blocking technology, you can reduce nighttime cortisol levels, resulting in greater relaxation and rejuvenation.

Investing in high-quality light-blocking technology such as SPV NightTime glasses helps you obtain all of these benefits and much more. With our lenses, you can rest assured knowing 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, unlike natural light, which humans are meant to receive. Unfortunately, many of the devices and bulbs we use emit light that can disrupt sleep and the circadian rhythm.

Studies have shown that exposure to blue and green light in the wavelength range of 400 nm to 570 nm confuses the brain, making it believe it is daytime, and suppresses the production of melatonin, the sleep hormone, which makes it harder to fall asleep, stay asleep, and achieve deep sleep.

But where does this artificial light come from? It is present in all electronic devices, such as the screens of our smartphones, TVs, and laptops, as well as in the bulbs in our homes and public places. Even the refrigerator light emits blue light, which can disrupt our sleep if we are exposed to it at night.

While generic blue-light blocking glasses on the market only filter part of the blue light and not green light, our NightTime glasses are specifically designed to provide optimal protection against these harmful frequencies.

Not only do they block blue and green light, but they also reduce overall brightness to signal to your body that it is time to relax and prepare for sleep.

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

It is important that nighttime blue-filter glasses block blue light because blue and green light are known to suppress melatonin production and disrupt our sleep.

While blue light has been shown to have the greatest 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-filter glasses on the market only partially block blue light up to 500 nm, leaving out a significant portion of green light that can still disrupt our sleep. According to the melatonin suppression zone, melatonin suppression is 70% at 500 nm.

This is where SPV NightTime glasses stand out in harmonizing nighttime circadian light. They use a special harmonizing pigment that blocks 100% of blue and green light up to 540 nm, and 95% of green light between 540 and 570 nm, while allowing maximum transmission of other beneficial orange and red wavelengths.

This unique technology ensures that our glasses provide maximum protection against sleep-disrupting light, supporting optimal melatonin production and better sleep quality. Our customers have noticed a significant difference in their sleep quality after switching from generic blue-blocking glasses to SPV glasses.

In summary, blocking blue and green light is crucial for better sleep and for maintaining healthy circadian rhythms.

To better understand why it is essential to eliminate all light leaks, think of them as a leaky pipe.
If a pipe has a leak, water will continue to flow through it even if you partially block it. In the same way, if glasses have light leaks, unwanted light will continue to enter even if certain frequencies are filtered. This light leakage can negatively affect sleep quality, hormones, and circadian rhythms.

After testing dozens of orange- and red-tinted glasses, SPV has found that many of these glasses present light leaks of between 5% and 30% of unwanted frequencies that still enter across the spectrum. This makes these technologies much less effective at protecting sleep, hormones, and circadian rhythms.

SPV NightTime lenses, on the other hand, block all the frequencies that need to be blocked. SPV achieves this through the use of a high-quality lens tint formulated by a professional collaborating laboratory after several years of research and development. This tint is the most advanced currently available, providing a uniform and harmonious color that filters out unwanted light frequencies.

If you truly want to protect your sleep, hormones, and circadian rhythms, choose nighttime blue-filter glasses that eliminate 100% of light leaks. SPV technology achieves this goal with the most advanced and effective technology currently available.
