Our favourite pieces of technology are nearly impossible to avoid, so don’t! These tips will help your eyes when it comes to all that time spent in front of screens.
Phones, Tablets, & Computer Screens all emit what we optometrists call blue light. The light that’s emitted from a phone, tablet, or computer screen is meant to help illuminate text and graphics. As a side effect, the cones and rods in our eyes are fed a constant stream of light throughout the day. This is not natural for our vision and poses the risk of overexerting our eyes as a result.
Haze Protection, Blue Light Glasses: For teens and children, new research suggests that blue light exposure from screens is not as harmful as once thought. In fact, natural blue light from the sun plays an essential role in reducing myopia (nearsightedness) in children and teens. Studies from the early 2020s indicate that kids who spend more time outdoors experience a slower progression of myopia, and this benefit is linked to natural blue light exposure.
Because of these findings, Dr. Doig and Dr. Chorel have paused recommending blue light-blocking lenses for children and teens. Instead, we strongly encourage parents to promote outdoor activities to support their child’s visual development. While blue light-blocking lenses may still benefit some adults experiencing digital eye strain, the best approach for children is simply more time outside.
Avoid Contrast and Take Breaks The world's leading audio engineers advise young music producers to take breaks when mixing and mastering, in order to protect their ears. The same rule applies for those of us whose days are spent looking at a computer screen. In order to give your eyes a break from the harsh blue light you face for hours a day, break up your periods of work with some other activity. Get up to look out of a window when you're on the phone, get off your smartphone during breaks, or bring something to the office like a yo-yo, Rubik's Cube, or juggling balls if you really want to get out of your chair! If you can make the time, these activities are great to prevent carpal tunnel syndrome as well.
