Spending hours looking at a computer or phone screen has become inescapable in many workplaces: More than 104 million Americans are exposed to excessive screen time — defined as seven or more hours per day — including about 70% of people who have an office job, according to aEven as few as two hours daily on a device can cause eye problems, says Dr. Steven Reed, an optometrist and president of the AOA.
A lot of people have their computer screens positioned too high. Yours should sit slightly below your line of sight so you don't have to raise your head, Reed advises. Having your head in the wrong position can cause symptoms like neck pain and headaches, he adds.You should also move your computer screen to an arms-length away and pull your smartphone farther away from your eyes, recommends Dr.
"When you're focused on anything up close, the muscles inside the eyes that help you focus … can get tired," Reed says."When you look up at something further than 20 feet, those muscles tend to relax. You're giving them options to relax."Outside the workplace, avoid using devices up to an hour or two before bedtime to improve your quality of sleep, Reed says.
When looking at a computer screen, it's a reflex to not blink as much, for instance, which can give rise to dry eye, Reed explains.
