      Eye strain a growing concern as kids use digital devices

      In a day and age where smartphones and similar technologies are pervasive, many parents start to wonder if it has an effect on their children's eyes.

      Recent studies show that near-sightedness has increased from 25 percent in the 1970's to 41 percent today. More doctors have also seen an increase in the number of young children who need glasses.

      As more schools are now relying on items such as iPads and computers to do work both at home and school, more kids are spending time looking closely at the screens.

      Experts say it's important for parents to use everything in moderation, making sure kids take breaks from these items and be active.

      "If they are going to give the kids some guidance on how much time they can spend on the computer, break up on that time on doing something outside in the daylight like get out and walk the dog or something for 20 minutes. It will do a lot for their eyes and physically too,?? said Ronald Brand, O.D. with the International Eye Care Center.

      Brand says having exposure to bright outdoor light is good for the children's eyes and stimulates the brain and the most common sign of near sightedness is squinting.
