North Ray's blue light glasses and clip-on lenses are the result of careful product development, combining scientific groundwork, advanced blue light blocking technologies and product comfort. We care about well-being and are focused on creating a product line that supports you every moment of the day.
Artificial blue light should not be avoided at will. The most important thing is to do it thoughtfully, taking into account different times of day . 100% blue light blocking is not the goal, but optimal blue light filtering from morning to evening and night , which supports your body's natural rhythm. North Ray's blue light glasses not only protect your eyes from harmful blue light, but they also support your natural circadian rhythm and improve the quality of your sleep.
Our goal is for each pair of glasses to offer you the perfect balance between protection and a comfortable wearing experience, so you can live more energetically and more refreshed every day.
North Ray Sunglasses
Excessive exposure to blue light during the day can cause eye strain, decreased concentration, and headaches and migraines as your eyes try to adjust to the constant bright light. Prolonged exposure can also increase the risk of developing digital eye strain, which is associated with blurred vision, photophobia, and dry eyes.
Research also suggests that continuous exposure to blue light may be associated with long-term risks to eye health, such as macular degeneration, cataracts, and the development of nearsightedness. While the links to these conditions require further research, it is clear that avoiding harmful blue light will support the well-being of your eyes now and in the future.
North Ray's optimally designed sunglasses provide highly effective protection against the harmful effects of blue light, which you encounter especially during the day when spending time in front of screens or under artificial lights. The glasses block up to 84.89% of blue light in the wavelength range of 400–480 nm , and at the particularly harmful wavelength of 450 nm, the filtering increases to up to 98% . We have developed our sunglasses to take into account the effects of all light spectra during daytime use. The sunglasses effectively filter out harmful blue light, but let through just the right amount of cyan light (490–520 nm) . This spectrum of light is vital for maintaining the body's biological clock and circadian rhythm, as it activates the melanopsin receptors in the eyes, which send signals about the ambient light conditions to the body's biological clock.
This careful balance between blue light filtering and cyan light transmission ensures your eyes are protected without compromise. The presence of cyan light completes the overall effect, supporting your natural circadian rhythm and helping you stay energized and alert throughout the day.
This filtering solution is based on rigorous scientific research. Blue light blocking is a key factor in maintaining eye health and circadian rhythms (Hankins et al., 2008). At the same time, an optimal balance of cyan light supports the activation of melanopsin receptors, which are important in regulating the body's biological clock (Gooley et al., 2010).
North Ray evening glasses
North Ray's night vision glasses are carefully designed to protect against the harmful effects of blue light in the evening, when the harmful effects of blue light are at their strongest. Our glasses block up to 99% of blue light (400-480 nm), which is known to be the biggest disruptor of melatonin production and therefore of falling asleep. Blue light delays the body's natural sleep onset and can disrupt deep sleep stages. With our night vision glasses, you eliminate this problem so you can enjoy undisturbed sleep and wake up refreshed for the next day.
Our evening glasses also have an optimized filter for green light (490–560 nm). The evening glasses block about 70% of this light, which is an important part of maintaining your circadian rhythm. Green light is not as strong a melatonin inhibitor as blue light, but excessive exposure to it in the evening can still affect your sleep. This is why our evening glasses do not block green light completely, but let through just the right amount to support your biological clock without affecting your ability to fall asleep.
Studies show that complete green light blocking is not necessary, as even a small amount of this light can support the maintenance of the biological clock and prepare the body for sleep in the right way (Yasukouchi, 2008). Excessive green light filtering, on the other hand, can inhibit melatonin production too early in the evening and make it difficult to fall asleep.
North Ray night glasses offer the perfect balance between effective blue light filtering and natural regulation of your biological clock. They ensure that your body's internal clock remains in tune without being disrupted by excessive light exposure, supporting deeper and more restorative sleep. This way, you can enjoy restful nights and wake up to a new day full of energy.
Scientific studies support the effectiveness of these filtering principles and highlight the importance of protecting the body from both blue light and excessive green light in the evening (Gooley et al., 2010; Yasukouchi, 2008). North Ray's evening glasses are based on this research, ensuring their scientifically optimized performance and effectiveness.
North Ray night vision goggles
North Ray night glasses are designed as the perfect solution to protect against the harmful effects of blue and green light at night, when the body needs deep recovery and restful sleep. Our glasses block virtually all blue light (280-500nm) , which is critical for supporting melatonin production. Specifically, at the 450nm wavelength , known to be the most effective melatonin inhibitor, our glasses have only 1.11% transmission , making them the most effective night glasses solution on the market.
Blue light is not the only factor that can disrupt sleep. Our night glasses are also optimized to filter out green light (500-570 nm) . This spectrum of light can affect melatonin production and circadian rhythms, especially with high exposure at night. Our glasses filter out over 90% of green light , which significantly eliminates the risk of circadian rhythm disruption and ensures that the body has the best possible conditions to calm down and fall asleep. Unlike evening glasses, which balance light filtering to support your natural rhythm, our night glasses offer maximum protection from all harmful light ranges. The comprehensive protection (280-570 nm) means you can safely wear them in the late evening and throughout the night without worrying about the light disrupting your sleep.
Whether it’s a morning that requires clear thinking and focus, an evening when you want to wind down after a long day, or a night when you’re looking for a deep, restorative sleep, our glasses will support you every step of the way. Our goal is clear; we want to provide you with complete protection from eye strain and help you live an energetic, healthy life day in and day out. North Ray blue light glasses are scientifically optimized and extremely comfortable to wear. Our wide range of glasses ensures that you’ll find the right option for you, supporting your life without blue light interference from morning to evening and into the night.
