That’s because when staring at those devices, you may be blinking somewhere around 50 percent less often that you do when looking at other everyday things, says Dr. Christopher Starr, an associate professor of ophthalmology at Weill Cornell Medical College. He explained on “CBS This Morning,” “Normally, we blink about 20 times per minute. It can drop to eight or 10 times a minute. And when you’re not blinking, the tears that are on your ocular surface just evaporate. You’re not distributing new, healthy, clean tears across the ocular surface.” Another thing that can contribute to the dry-eye feeling is the lack of oil being distributed to the eye via your eyelid. “When we blink, we push out a little bit of oil,” Starr said.

That means more than 12 million children go to school and cannot see the blackboard or even read their textbooks. The American Academy of Pediatrics states, “Eye examination and vision assessment are vital for the detection of conditions that result in blindness …

Users of PediaVision’s Spot Vision Screener Honor Children’s Eye Health and Safety Month with Back-to-School Screenings
The researchers said their findings may suggest new ways to help people with age-related macular degeneration better cope with vision loss. The disease causes progressive loss of so-called “foveal” vision, leading to visual impairment and blindness. The fovea is the small, central area of the retina. People constantly move their eyes to aim the fovea at different parts of a scene in order to create a picture of their surroundings, explained the authors of the study published Aug. 15 in the journal Current Biology.
