Are you spending hours on your computer, smartphone, or other digital device? If so, you're exposing your eyes to harsh blue light that can cause eye strain. Learn more about light wavelengths, common causes of eye strain, and all about blue light glasses. Discover how these digital eyeglasses may be able to protect your eyes and help you get a great night's sleep. How Light Affects Your Eyes The different colors of light are caused by different wavelengths. As the wavelengths increase, the light moves from blue to green, yellow, orange, and then red. Increased wavelengths reduce the risk of eye damage from long-term exposure to this form of light. Smaller wavelengths have an increased frequency. High-frequency light can be damaging to your eyes. Extreme light frequency is ultraviolet light, which not only damages your eyes but is the cause of your skin being sunburned. Just like sunscreen for your body, prescription blue light glasses are designed to protect your eyes from the damaging effects of blue light. Research is still being conducted on these lenses. There are early signs that blue light filtering technology may protect your eyes, particularly from continued exposure to computer screens. Sources of Blue Light The most common natural source of blue light is the sun. This form of light affects your body's circadian rhythm, which helps prepare you for sleep at night and wakes you in the morning. Natural rhythms of blue light throughout the day aren't necessarily damaging to your eyes. There are, however, many unnatural sources of blue light. Here are some common blue light sources that you may experience throughout your day:
There are a few reasons that unnatural blue light can be damaging to your eyes. First, it can cause eye strain. People typically blink less when focusing on a digital screen, which dries out their eyes and causes discomfort. As a short-wavelength light, blue light has more energy than green, orange, or red light. This can damage your eyes over time. Blurry vision, irritated eyes, headaches, and neck pain are all common discomforts caused by long-term blue light exposure. Because your eyes are only used to seeing blue light as part of sunlight, artificial blue light can alter your natural circadian rhythm. Computer or smartphone use shortly before bed can create disruptions in your circadian rhythm. If you are having trouble sleeping or feeling irritable, depressed, or anxious, it could be caused by exposure to blue light. How To Reduce the Effects of Blue Light Thankfully, there are ways to reduce your exposure to blue light. Here are some tips to reduce the eye strain caused by normal computer usage. First, schedule some breaks from your screen. Focusing on a computer screen for hours at a time is harmful to your eyes, but staring at an object far away every 20 minutes can help relax your eyes. Use the 20-20-20 rule: Choose an object that's 20 feet away and focus on it for 20 seconds every 20 minutes of your workday. You may be sitting too close to your screen. Try to sit 25 inches away from your screen. An arm's length between you and your computer screen can reduce eye fatigue. If your eyes are frequently drying out during your workday, regular use of eye drops can help. Focusing on blinking while working is a natural way to keep your eyes lubricated. These tips reduce the effects of blue light, but blue light blocking glasses can help filter out the light entirely. Digital eyeglasses are specifically designed to filter out these high-wavelength light sources as you work or enjoy an evening watching TV. Blue light eyeglasses can come in a wide range of styles and types. Here are just a few features you can add to your glasses:
Personalize your eyewear to your style, prescription, and lifestyle. Digital eyeglasses may help reduce the blue light strain on your eyes, helping you sleep easily and get through the workday without eye strain or neck pain. FAQsWhy Is Blue Light Bad for Your Eyes?
Research shows that frequent exposure to blue light, particularly digital devices, can lead to blurry vision, headaches, neck and back pain, and eye irritation. While not conclusive, it appears that continued exposure to blue light can damage your eyes and affect your sleep cycle in negative ways.
