Your Devices Are Ruining Your Sleep Cycle—Here's Why
When really considered, it's alarming just how much time we spend staring at our devices. Your phone is probably the first thing you grab in the morning to check the time, the weather, and whatever emails came in while you were snoozing. If you're like most, once you get to work, you spend a good portion of your day with your eyes fixed to your computer. When you get home from a long day of work, it's your tablet or television at the center of attention as you wind down for some leisure time with your favourite shows. All that said, your eyes are getting a lot of nearly uninterrupted screentime. So even if you have perfect vision and therefore don't wear glasses, you may want to reconsider.
Heavy screentime has been associated with headaches, eye strain, and unhealthy sleeping patterns. The phenomenon has to do with the electronics giving off "blue light," the part of the light spectrum that penetrates your eye the deepest. Before electricity and all the technological playthings we've become accustomed to, humans would be exposed to blue light from the sun. Thus, we're still wired to get drowsy in its absence and wake up when our eyes sense it. So during our professional and recreational time when we're inundated by blue light, our brains become confused.
A recent Business Insider article notes that "there's no hard proof that lowering the amount of blue light you take in can help you sleep better, or cure insomnia, but there is a lot of debate about it." Those who've taken measures to combat their blue light intake, BI points out, have seen positive results. For example, Brandt Ranj, the author of the article, recommends wearing computer glasses specifically equipped to reduce the intake of blue light while you're staring at your various screens. In addition to improved sleep, he's noticed less eye strain and irritation, even after using electronic devices all day.
So if you've ever noticed your eyes tiring after a long day of staring at screens or the onset of headaches when you haven't broken away from your computer, in addition to reducing your screentime, you may want to consider trying out a pair of glasses that can reduce the amount of blue light intake for you.
