The verdict: Computer use can definitely strain your eyes — but there are ways to combat the damage
Studies have shown that between 50 and 90% of people who work in front of a computer screen have some symptoms of eye trouble.
“We definitely see a lot of people who complain of eyestrain,” says opthalmologist Dr. Brian Boxer Wachler. “Hours upon hours of close focusing without taking a break is usually the main culprit.”
The problem is so common, there’s even a name for it: Computer Vision Syndrome (CVS).
Wachler says that people usually blink around 18 times per minute, which refreshes the eyes naturally. But blink rates are reduced when staring at a computer screen or other digital device, and this can make your eyes burn, dry out, turn red or feel itchy.
Sitting too close to your computer monitor, or holding a digital device closer to your eyes than you would normally hold a book or newspaper, also poses a problem, according to Wachler. “This forces your eyes to work harder than usual as you strain to focus on tiny font sizes,” he warns.
