20 Jun Blue Light Protection
Blue Light Protection
Our digital devices fit so naturally into our daily lives that it’s easy to forget we need blue light protection. That’s because our digital devices expose us to higher than normal amounts of blue light. As a result, you may experience digital eye strain and/or eye fatigue from too much use. While blue light is both good and bad, studies suggest that too much exposure can lead to damaged retinal cells causing vision problems like age-related macular degeneration.
The truth is, today there are multiple sources of blue light including sunlight, indoor lighting, digital devices, computers, and TVs that our eyes are absorbing. When you consider this and the fact the average adult devotes more than 11 hours to screen time, taking the necessary precautions to protect our vision is important. With this in mind, we offer so insight on why blue light protection is so important.
Like ultraviolet radiation, visible blue light (the portion of the visible light spectrum with the shortest wavelengths and highest energy) has both benefits and dangers.
Digital Eye Strain & Blue Light
Digital device use has increased so substantially, that extensive daily use for both social and professional purposes is now normal. The problem with this is that blue light goes into the eye, but the cornea and crystalline lens can’t filter it out. This means it goes straight to the back of the eye. While long term exposure may lead to macular damage, in the short term it can lead to eye strain. Symptoms of eye strain can result in blurry vision, trouble focusing, tired eyes, red eyes, dry eyes, or headaches. This happens because your eyes are trying to focus on the device’s screen, so your eye muscles are being pulled together constantly. And, because your eyes are working extra hard to cope with the blue light, you begin to experience eye strain.
What Causes Eye Strain?
Just like the muscles in your body, your eyes can get tired too. As an example, imagine flexing your biceps 10 to 11 hours a day for a full week. Eventually, they would get tired and stop working as well as they could. Similarly, when you look at a computer or digital device or both, all day your eyes have to focus and refocus all the time. They move back and forth as you read, up and down as you look at something and back up to type, all requiring a lot of effort from your eye muscles. This results in what is commonly called, digital eye strain, or computer vision syndrome. Although you may not be able to change the nature of your job and other factors that can cause eye strain and over exposure to blue light, you can take steps to protect your eyes.
How to Protect Your Eyes From Blue Light
Since most of us devote a considerable amount of hours to screen time, we risk overexposure to blue light. Overexposure to harmful blue light, especially outside in the sun and through constant use of electronic devices and screens is why protecting your vision has never been more important. So, use the 20/20/20 rule, look away from your computer or digital device every 20 minutes for 20 seconds about 20 feet away to help your eyes refocus and avoid digital eye strain. Also, keep the lighting balanced around your computer, and invest in blue light glasses. Ultimately, scheduling an eye exam is the best way to make sure you’re doing everything you can to protect your eyes from blue light and eye strain.
To help alleviate digital eye strain, follow the 20-20-20 rule.
Blue Light Glasses
You will spend 3,500 hours looking at screens this year, so make them enjoyable. Blue light lenses can help you improve clarity, focus, and performance while reducing the risk of developing symptoms of digital eye strain. We all know that staring at screens throughout the day is pretty much unavoidable. But all that staring can be hard on your eyes and may cause digital eye strain.
The right lenses can help prevent the overexertion of certain muscles that help your eyes focus, keeping your eyes relaxed and comfortable so you can get the most out of your screen life. Eyewear is available with lenses featuring magnification, plus anti-reflective and blue light-filtering capabilities, as well as select contact lenses, to help reduce the symptoms of digital eye strain
Diagnosing & Treating Eye Strain
Eye strain is easy to treat and can be diagnosed through a comprehensive eye exam. Getting an annual eye exam is the most important thing you can to protect your eyesight. For anyone who is experiencing eye strain as a result of prolonged computer use, there are specialized lenses that can help relieve the symptoms. Computer glasses are a great solution for reducing both digital eye strain and the potentially damaging effects that increased digital use can have on vision.
