Why clear blue light blocking glasses are insufficient
If we start from the conclusion, Clear blue light glasses do not actually BLOCK blue light. How many people have found that clear blue light blocking glasses have helped them sleep and protect their eyes? Not many. The reason is because the clear lenses don't block blue light, they only filter it! ﾠ Blocking vs Filtering Blue light has a wavelength range from approximately 400nm to 500nm . Several reliable studies have shown that the most harmful blue light wavelength range is between 440 nm and 500 nm. BUT! All transparent blue light blocking glasses sold on the market do not block wavelengths longer than 420 nm. Also important to note here is that there is a difference between filtering and blocking! Filtering literally means filtering out a certain wavelength of light. Transparent blue light not only does not block the wavelength range above 420nm, but it does not even block light below that level, it only filters about 30% to 60% of the wavelength. In other words, clear blue light glasses are filtering glasses! Not blocking glasses! Other companies only use the word blue light as a marketing tool, not actually prevent blue light from having a harmful effect on the human body. ﾠNo other clear blue light blocking glasses can ever block the full range of blue light. For blue light blocking glasses to make a noticeable difference to your sleep, they must block 100% of the entire spectrum of blue light. So why do blue light blocking glasses have to be yellow/red? As we learned in blue light, all light comes in rainbow colors. White light that comes from most indoor lights is a combination of red, orange, yellow, green, and blue wavelength. When it passes through glasses that block blue light, the colors that pass through are red, orange, yellow, and green, and these colors combine to produce yellow. This is why day lenses are yellow! Also, if you block blue and green, the colors that pass through are red, orange, and yellow, and these colors combine to make red. This is why night lenses are red! Most “blue light” glasses in the country are completely transparent lenses with only a shiny blue reflective coating. If the lenses does not have a small amount of yellow or red tint, it probably won't be blocking a significant portion of the harmful blue light emitted from LED and screen devices. Eye protection Day lenses completely block light from 400nm to 460nm, the most harmful range of artificial blue light. Sleep quality Night lenses, which are suitable for wearing at night, provide a noticeable improvement in sleep quality by completely blocking 100% of blue light and green light from 400nm to 550nm, which have a negative effect on sleep.

Foundation of health circadian rhythm
All functions in our body do not occur without a reason. All functions are constantly changing and require timely interaction to function properly. The most important change in the environment is the regular shift between light and dark. Therefore, the body follows these changes and has developed a time cycle to functions of the body, allowing us to survive and function in various environments. This cycle is called “circadian rhythm.” In Latin, circadian rhythm means “about a day.” Circadian rhythms controls the body's production of serotonin, dopamine, growth hormone, testosterone, and all other hormones essential for health and athletic performance. Above all, it is responsible for the production of melatonin, which is essential for sleep quality, damage repair, and recovery ability after strenuous exercise. For billions of years, the Sun has been the only light source capable of stimulating our circadian rhythms. Then, before we learned about circadian rhythm, the light bulb was invented to allow people work more hours. Over time, artificial light has evolved to make human body feel more awake and alert in the evening by adding wavelengths of blue light, a component of white light that affects circadian rhythm. As humans began to be exposed to more and more blue light, this began to affect circadian rhythm. Exposure to blue light wavelengths at night has a negative effect on melatonin secretion, which prevents us from falling into a deep sleep. It also makes you feel more tired and less energetic during the day and promotes aging. The most harmful thing of all is that these diseases are all fundamentally caused by artificial blue light exposure at night. heart disease, diabetes, obesity, alzheimer's, autoimmune disease, Cancer All these causes starts with disrupting the rhythm that controls our biological changes. With research showing the dangers of exposure to artificial light, we have two options. 1. Escape into the wild and give up the convenience and stability of the modern lifestyle for which our ancestors worked so hard . 2.Use this knowledge intelligently to maintain a healthy circadian rhythm in modern society. So how can we achieve these circadian rhythm-friendly practices? 1. Just like our ancestors did, wake up at sunrise and make it a priority to go outdoors and receive sunlight. If possible, watch the sun rise in person. By starting your day with natural, beneficial light, you can get your circadian rhythm right and get one step closer to optimal health. 2. Spend as much time as possible outdoors during the day. Exposing your eyes and body to the full spectrum of solar rays essential to the circadian rhythm, whether in the shade or in direct sunlight, you provide your body with a variety of biological virtuous processes. For people in occupations where this practice is not easy, sitting next to an open window can be a good alternative. Closed windows filter out much of the red, infrared and near infrared wavelengths, which are the most healing rays of sunlight, and serve to balance the high-energy blue and ultraviolet wavelengths. In other words, receiving sunlight through a closed window is a distorted ray that deviates from the full spectrum of sunlight, so it is difficult to expect the desired effect and, in fact, has a harmful effect. Therefore, when we inevitably have to stay indoors during the day, we need Day lenses to protect our bodies from artificial lighting and LED fluorescent lights, which stress the body and cause great harm to health. As night comes and the sun sets, you should wear Night lenses to synchronize your circadian rhythm with rhythm of nature and protect your sleep by minimizing exposure to the harmful blue light that all modern lighting, especially screen devices. Day lenses block 95% of artificial blue light. Night lenses block 100% of artificial blue light and green light. So the next question you may ask would be “Why LUCIER glasses and not products from other cheaper brands?" Here's why: Most blue light blockers on the market don't sufficiently block the most harmful wavelengths of blue light. In particular, glasses with transparent lenses uses the word “blue light” as a marketing goal, but it is difficult to expect any real effect. Blue light contains a wide wavelength of approximately 400 to 500 nanometers (nm). All blue light at this wavelength has been proven to be harmful to circadian rhythm and health when it comes from artificial light or not from a full-spectrum light source like the sun. Most companies that make “blue light” blocking glasses do not change the color of the lenses because they believe that customers will not want to wear colored lenses. However, when a lens is clear, it means that the visible rays passing through it do not change. Most “blue light” lenses in the market are completely transparent lenses with only a shiny blue anti-reflective coating. These lenses can generally block blue light up to 420 nm, but not up to 460 nm, which is the most harmful range emitted by modern lighting and screen devices. Studies have shown that blocking light lower than the range between 400 and 460 nm is not an acceptable compromise for optimal health, so the effectiveness of clear blue light glasses is disappointingly insufficient! “A half truth leads to a full lie”-Benjamin Franklin If you begin to deeply understand the principles of sunlight and nature, you can realize that, if you break down and artificially imitate nature, it will usually cause bigger problems. LUCIER will do our best to help you regain optimal health through complete solutions rather than providing distorted information.

Effects of blue light on sleep
How does blue light affect sleep? First, let's take a brief look at proper sleeping patterns. ﾠThe body recognizes day and night through constant changes in the sun and controls all hormone secretions through the biological clock. It works to keep you awake and focused during the day, and guides you to achieve deep repair and restful sleep at night. The phenomenon of falling asleep and waking up through the process of hormonal secretion at the right time is called Circadian rhythm. What is circadian rhythm? ﾠ The Ideal function of circadian rhythm is, During the day - the body secretes cortisol , serotonin , dopamine and other essential hormones to keep us alert and focused. At night - as the sun sets and it gets dark, melatonin is secreted, which is essential for restful sleep and deep recovery. Dark nights are essential for the secretion of sleep hormone (melatonin). BUT! The circadian rhythm disrupted by excessive artificial light at night suppresses the secretion of melatonin and hormones necessary for growth and recovery, and this pattern is repeated, leads to chronic fatigue, poor sleep quality and insomnia. However, Modern society is a world where we cannot live without artificial light at night. From LED light bulbs and fluorescent lights to cell phones and computers, they are all sources of blue light, the dominant wavelength of artificial light. And this blue light sends a signal to your body through your eyes that it needs to be awake, suppressing sleep hormones! ﾠ Exposure to artificial blue light, especially 1-2 hours before going to sleep, can have detrimental long-term effects on the body. How does blue light adversely affect sleep? Blue light is a wavelength of high energy sources. Higher energy means light travels deeper into the brain through the eyes.What happens when you receive artificial blue light at night instead of during the day: High-energy blue light passes through the eyes and reaches the brain. The brain recognizes that it is morning time and sends a signal to every cell in the body to be awake. Hormones that must be secreted during the day continue at night. Recovery, regeneration, and growth cannot occur properly If you are unable to get a quality sleep. As this process is repeated, we encounter various diseases and chronic fatigue through a vicious cycle. Blue light is necessary during the day when we need to be awake, but at night, you need to send clear signals to your brain and body that it is time to sleep . Our eyes cannot detect the difference between natural and artificial blue light. The brain only receives information from high-energy sources through blue light and sends signals to the human body. However, blue light before going to sleep artificially brightens the dark night, reducing the secretion of melatonin (sleep hormone), which is a major factor in adversely affecting sleep. ﾠSo what can we do to effectively block blue light at night?If we could wake up at sunrise , face darkness at sunset , and use fire as our only source of light at night, as our ancestors did, we would be able to maintain an optimal circadian rhythm and sleep pattern. However, for modern people for whom this practice is practically impossible, LUCIER has developed glasses that block 100% of blue light so that even modern people can maintain healthier circadian rhythm! LUCIER yellow Day Lenses are designed to block 95% of the most harmful range of artificial blue light while allowing necessary colors to pass through for perception, functionality and health. ﾠ LUCIER red night lenses blocks 100% of artificial blue and green light, which are proven to be harmful to health and disrupt sleep patterns and circadian rhythm.
