Beyond that, it helps regulate your body’s circadian rhythm or body clock, which helps you stay awake during the day and go to sleep at night. Various studies explore how a healthy dose of blue light ⦠An example: A chain of stores in the United Kingdom, Boots Ltd., was fined 40,000 pounds in 2017 for misleading advertising that said digital blue light caused retinal damage, and ⦠âProducts created to block out blue light minimize eyestrain when using computers and digital devices, but have not been tested or shown to prevent any type of eye disease.â. As such, excessive and prolonged blue light exposure can damage the light-sensitive retinal cells. Many of us know that it is emitted from our digital devices and LED lights, but did you know that it is also emitted by the sun? It's best not to wear blue light glasses when youâre outside in the sun -simply because there is no need, and you do not want to filter the beneficial natural light from your eyes. The higher levels of blue light place more strain on the eyeâs focusing system than do printed materials. I could go on, but I think itâs more important to help you decipher blue light myth from blue light ⦠developing a well-balanced and healthy relationship with the screens that brain to secrete less melatonin during daylight.

Blue light is more energetic than white light, which has raised some concern about the risks of long-term exposure. This tells us when we are tired or should be awake. The main risk factors for these eye diseases are age, genetic factors, UV light, smoking and poor nutrition more than digital device use. The effects of this disruption can be likened to âWe are not designed to be using our phones and tablets 6 inches from our faces, particularly when we are lying in bed with the TV on,â Gordon said. This increased This myth ⦠poor night’s sleep and the ensuing grogginess you have to deal with the next Learn more about UAB's COVID-19 health and safety policies, © 2021 The University of Alabama at Birmingham. In fact, sunlight is the biggest source of blue light and until recently (before the Covid-19 pandemic, that is), we have been getting most of our exposure to it when we go outdoors during daylight. Blue light is normally transmitted through the eye to the retina, because it is visible light that our eyes are designed to receive. For people who spend significant hours on a computer or other digital device, these lenses may provide some relief and comfort. Adam Gordon, O.D., clinical associate professor at the University of Alabama at Birmingham School of Optometry, believes overuse and exposure to blue light may lead to eyestrain and focusing problems, but does not appear to cause long-term harm, eye disease or damage to the retina. Dozens of studies have investigated whether exposure to blue light over time could cause serious, long-term eye damage. Exposure to blue light may increase Digital eye strain. Part of the visible light spectrum, blue light is the high-energy light just beyond the potentially harmful ultraviolet light. As with many things in life, blue light can be beneficial The latest trend in eyewear is actually to see lessâby filtering out certain parts of the visible light spectrum, particularly blue light. More specifically, the blue light emitted from the Myth#4: Blue Light Blocking Glasses Can Damage Your Eyes If You Get Them Without Prescription. One insect study found that increased exposure to blue light also caused brain damage (called neurodegenera-tion) and an early death. Exposure to blue light during daytime can improve energy and alertness, boosts your mood and your productivity. question is – it can be good and bad for us!

Compact fluorescent light bulbs, high-intensity headlights and other LED lighting do emit higher blue light energy than more traditional incandescent light bulbs, causing excess exposure to blue light than we received before. bed and get a good night’s sleep. When viewing digital devices, the eyes are looking at a pixelated image that is rapidly alternating or flickering multiple times per second. Turn off your devices one to two hours before going to bed to trigger the release of melatonin, giving it a chance to increase just before dozing off into deep sleep. Blue light is of concern because it has more energy per photon of light than other colors in the visible spectrum, i.e. As it turns out, your screens may be to blame for a strain! Digital eyestrain leads to dry eyes and puts strain on the muscles that help the eye focus. Prolonged blue light exposure may cause digital eye strain. The eye is not good at blocking blue light. When staring at a digital device, the eye does not blink as frequently, and this causes faster disruption and evaporation of the tear film that protects the ocular surface. One ophthalmologist and retina surgeon, Abdhish R. Bhavsar, MD, a clinical spokesperson for the American Academy of Ophthalmology, says wearing blue light filter glasses to prevent eye damage is "a big urban myth." So you may be tempted to reach for blue light blocking glasses to help your eyes. sleep.

Nearly 90 percent of adults use digital devices for two or more hours per day, according to The Vision Councilâs 2016 Digital Eye Strain Report, exposing consumers to blue light that some suggest is dangerous. Blue light is everywhere, and our eyes are constantly There are numerous eyeglass lenses now available to selectively block out the high-energy blue light that contributes to the fatigue and strain placed on the eyeâs focusing system. acuity, or the sharpness of the eye. For every 20 minutes of digital device use, look away for 20 seconds focusing on something 20 feet away. Why not block all blue light, all the time? One of the physiological benefits of visual light, specifically blue light, is the relationship with our internal circadian clock. production and increases tear evaporation – leading to dry eye and more eye An ophthalmologists discusses. âThere are many important benefits to blue light exposure. Macular degeneration, To further maintain comfortable vision while using digital devices, it is important to use the 20/20/20 rule. Digital eyestrain refers to blurred vision and other symptoms such as burning, stinging or tearing of the eyes associated with prolonged use of digital devices. Your email address will not be published. Digital devices such as TV screens, computer monitors, cellphones and tablets also emit significant levels of blue light. As part of the sleep/wake cycle, blue light triggers the suppression of melatonin in the brain, keeping us awake. Because blue light has a short wavelength, it produces a high amount of energy. Reduce blue light. While thereâs no strong scientific evidence that blue light from digital devices causes damage to your eyes, there is a growing concern that blue light can have long-term effects on our health. Prolonged blue light exposure may cause digital eye strain. âLens manufacturers have jumped on the band wagon of harmful blue light and are creating products that they claim will protect your eyes from macular degeneration or other eye diseases,â Gordon said. Weâve already established that blue light emitted from electronic ⦠Many blue-light blocking glasses you can buy also claim to help reduce eye strain. Research Results. There is also something known as blue-turquoise light⦠Adjust the color temperature of your screen to âwarmerâ colors such as red and orange to reduce blue light emission, which can also cause eye strain. Most eyeglass and sunglass lenses and many contact lenses have been developed to block out UV light. ⦠Adam Gordon, O.D., discusses blue light, including the lack of clinical evidence in advertisements overstating dangers, as well as the effects of blue light on sleep and eye discomfort. A large body of experimental and clinical evidence over 20-30 years shows that UV light can be harmful to the eye and contribute to diseases such as cataracts, pterygia or growths on the front of the eye, and perhaps macular degeneration. Don’t Let Your Kids Become Glued To Their Devices. This makes you sleepy and signals to you that it is time to go to Blue light is the visible light at the blue end of the spectrum.
