What Happens to Your Eyes When You Stare at Screens All Day - 0 views

  • Blue light from screens isn’t ruining your eyesThere’s a rumor that the blue light from smartphones (or other screens) can ruin your vision, perhaps even leading to blindness, but it’s not backed up by evidence. “The amount of light coming from a computer has never been demonstrated to cause any eye disease,” the American Academy of Opththalmology states in an article on their website recommending against blue-light-blocking glasses
  • Blue light-blocking filters also don’t block very much blue light; they just reduce it a tiny bit. (Experts have pointed out that you could get the same effect by holding your screen one inch farther away from your face
  • When you’re spending time in front of screens—any kind—the rule of thumb for eye health is the “20-20-20” rule. Every 20 minutes, take a 20-second break to look at something 20 feet away

The Art of Staying Focused in a Distracting World - The Atlantic - 0 views

  • continuous partial attention to describe the modern predicament of being constantly attuned to everything without fully concentrating on anythin
  • Continuous partial attention is neither good nor bad. We need different attention strategies in different contexts
  • The important thing for us as humans is to have the capacity to tap the attention strategy that will best serve us in any given momen

  • We may think that kids have a natural fascination with phones. Really, children have a fascination with whatever Mom and Dad find fascinating. If they are fascinated by the flowers coming up in the yard, that’s what the children are going to find fascinating. And if Mom and Dad can’t put down the device with the screen, the child is going to think, That’s where it’s all at, that’s where I need to be! I interviewed kids between the ages of 7 and 12 about this. They said things like “My mom should make eye contact with me when she talks to me” and “I used to watch TV with my dad, but now he has his iPad, and I watch by myself.”
  • What we’re doing now is modeling a primary relationship with screens, and a lack of eye contact with people. It ultimately can feed the development of a kind of sociopathy and psychopathy.

The Touch-Screen Generation - The Atlantic - 0 views

  • he hands are the instruments of man’s intelligence
  • In 2011, the American Academy of Pediatrics updated its policy on very young children and media. In 1999, the group had discouraged television viewing for children younger than 2, citing research on brain development that showed this age group’s critical need for “direct interactions with parents and other significant care givers.” The updated report began by acknowledging that things had changed significantly since then.
  • To date, no body of research has definitively proved that the iPad will make your preschooler smarter or teach her to speak Chinese, or alternatively that it will rust her neural circuitry—the device has been out for only three years, not much more than the time it takes some academics to find funding and gather research subjects. So what’s a parent to do?

  • Previously, young children had to be shown by their parents how to use a mouse or a remote, and the connection between what they were doing with their hand and what was happening on the screen took some time to grasp. But with the iPad, the connection is obvious, even to toddlers. Touch technology follows the same logic as shaking a rattle or knocking down a pile of blocks: the child swipes, and something immediately happens.
  • A more accurate point of comparison for a TV viewer’s physiological state would be that of someone deep in a book, says Kirkorian, because during both activities we are still, undistracted, and mentally active.
  • even very young children can be discriminating viewers—that they are not in fact brain-dead, but rather work hard to make sense of what they see and turn it into a coherent narrative that reflects what they already know of the world.
  • Children’s lives are filled with media at younger and younger ages, and we need to take advantage of what these technologies have to offer
  • A TV is static and lacks one of the most important things to toddlers, which is a “two-way exchange of information
  • That exchange was enough to nearly erase the video deficit.
  • That kind of contingent interaction (I do something, you respond) is what captivates a toddler and can be a significant source of learning for even very young children—learning that researchers hope the children can carry into the real world. It’s not exactly the ideal social partner the American Academy of Pediatrics craves. It’s certainly not a parent or caregiver. But it’s as good an approximation as we’ve ever come up with on a screen, and it’s why children’s-media researchers are so excited about the iPad’s potential.
  • something about tapping the screen, about getting feedback and being corrected in real time, is itself instructive, and enables the toddlers to absorb information accurately, regardless of its source
  • More important, she made the video demonstration explicitly interactive.
  • The statement from the American Academy of Pediatrics assumes a zero-sum game: an hour spent watching TV is an hour not spent with a parent. But parents know this is not how life works. There are enough hours in a day to go to school, play a game, and spend time with a parent, and generally these are different hours. Some people can get so drawn into screens that they want to do nothing else but play games. Experts say excessive video gaming is a real problem, but they debate whether it can be called an addiction and, if so, whether the term can be used for anything but a small portion of the population.
  • We live in a screen age, and to say to a kid, ‘I’d love for you to look at a book but I hate it when you look at the screen’ is just bizarre. It reflects our own prejudices and comfort zone. It’s nothing but fear of change, of being left out.”
  • a useful framework—what she calls the three C’s—for thinking about media consumption: content, context, and your child. She poses a series of questions—Do you think the content is appropriate? Is screen time a “relatively small part of your child’s interaction with you and the real world?”—and suggests tailoring your rules to the answers, child by child.
