NEW YORK (CBS NEWS) - Ever since Apple announced the third generation model for their popular tablet, everyone’s talking iPad. But not everyone’s going gaga over the new device — especially eye doctors. iPads, much like any computer or smartphone screen you stare at for awhile, might contribute to “computer vision syndrome,” a set of eye problems caused by staring at a screen for long periods of time without taking a break.

According to the American Optometric Association, symptoms of “computer vision syndrome” include eyestrain, headaches, blurred vision and dry eyes.
