Old Wives' Tales about Carrots, Eyes, and TV

I’ve got some eye intelligence for you. We’re going to debunk some old wives’ tales. Like, does eating carrots really help your vision. And does sitting too close to the TV ruin your child’s eyesight? Here are the facts, courtesy of MSNBC.

  • The first myth: Carrots can improve your vision. That happens to be true. Carrots contain beta-carotene, which improves night vision and keeps other chemicals from “fogging up” the lenses of your eyes. But carrots aren’t the only good source of Vitamin “A”. All orange fruits and veggies, along with milk are good sources, too.
  • Next eyesight myth: Two blue-eyed parents can’t have a child with brown eyes. Even though it’s rare, two blue-eyed parents can have a child with brown eyes. That’s because dominant genes can skip a generation. In other words, a person’s genes don’t necessarily show up in their children, but they can reappear in their grandchildren. So, if you’re the only person in your immediate family whose eyes aren’t blue, check out the pictures of your grandparents or great-grandparents. Your brown eyes probably came from one of them. 
  • And the last myth: Sitting too close to the TV is bad for your child’s eyes. That’s false. There’s no evidence that plunking down right in front of the TV damages their vision. In fact, the American Academy of Ophthalmology says that kids can actually focus up close without eyestrain better than adults. Why? Because younger eyes are better at using the specialized muscles that control the shape of the eye lens for focusing. But even though sitting near the TV won’t hurt them, for every hour a child watches TV every day before they turn 4, their risk of later attention problems goes up by 9%. So, for example, if your toddler watches 3 hours of TV a day, they’re almost 30% more likely to have problems paying attention by the time they start second grade. So stick to this guideline from the American Academy of Pediatrics: children under the age of 2 not be allowed to watch TV – period. For older kids, they should watch no more than 2 hours of TV a day.
