People of all ages are being exposed to more and more screen time, especially while working from home due to the coronavirus outbreak."Seventy percent of adults do report some sort of computer vision strain nowadays, and it's overtaken carpal tunnel syndrome as one of the main computer-related -- basically syndromes -- that's occurring," said eye specialist Dr. Patrick Scott, UofL Physicians.Scott said he's now treating one to two people per day with issues related to screen time use."We're using our iPads, our tablets, our light bulbs. We're being basically constantly hit with this high energy visible light," Scott said.Not all blue light is bad, but Scott said the increase in screen time use increases the exposure to the bad blue light and creates a negative impact on health.It can lead to headaches, vision problems and even weight gain, he said."When we're looking far away, the eye is in its natural state of rest. Then, when we focus in on a computer screen, we're now taxing the eye's muscle inside of the eye called the ciliary muscle and when we are focusing and forcing it to look at a certain distance from my eye to the screen. Here, it's really like flexing your bicep and holding it," Scott said.In children, increased screen time from tablets, computers and even TV can actually lead to long-term problems."What often happens is a lot of these kids will slip into what we call early onset presbyopia where they need a bifocal," he said.Scott recommends no screen time before bed and reducing it to just one or two hours per day. He also suggests using screens near a window or natural light, wearing blue light glasses and following the 20/20/20 rule."Every 20 minutes look at something that's 20 feet away. So when we do our eye exams, we always have the 20/20 test which is basically the 20 foot test and look at something for 20 seconds and what that does is it basically allows your eye to go back to look far away and help it to relax and slip back into its relaxed position or mode," Scott said.He added it is good to make sure everyone, especially children, are eating a diet rich in vitamins C, E and antioxidants to help with the health of the eyes.And don't forget to schedule an annual eye exam.
