Eye doctors offer suggestions like following what is known as the 20/20/20 rule.
NATHAN BONILLA-WARFORD: “Every twenty minutes, look away twenty feet or more for at least twenty seconds from whatever device you’re using.”
Twenty feet -- that's six meters.
Other suggestions include putting more distance between you and the device and using good lighting. Of course, another way to avoid eye strain is to spend less time looking at screens. Many experts say children should spend no more than two hours a day using digital devices -- with no screen time for children under two.
But not all eye doctors have noticed an increase in problems in children. Dr. David Hunter says he has not seen an increase in his practice as a pediatric ophthalmologist at Children’s Hospital Boston. He also serves as a spokesman for the American Academy of Ophthalmology.
Dr. Hunter thinks calling it a syndrome, as in computer vision syndrome, is a little much. He says the real problem is simple.
DAVID HUNTER: "Spending too much time in one place, focusing on one thing, not looking away from their work, etc."
And while this might be tiring to the eyes, he says, it will not cause permanent damage.
DAVID HUNTER: “While it is possible to develop fatigue looking at various screens for a long period of time, there’s certainly no evidence that it actually causes any damage to the eyes.”
