Learn : Is sitting too close to the TV really bad for your eyes?

"Move away from the TV, you're ruining your eyes!" It's a classic quote for nagging parents, The habitual warning does have some historical basis. Once upon a time, until about the late '60s, TVs did emit a small amount of radiation. It was measurable but
not harmful -- you could sit directly in front of the TV for hours a day and still not get the radiation dose of a run-of-the-mill X-ray. Still, it's understandable that parents might have felt uneasy with kids sitting close to the TV. In 1967, General Electric recalled 90,000 TVs because a factory error caused them to produce 10 to 10,000 times the usual amount of radiation . This was no doubt a big factor in the perpetuation of the "sit back!" warning.



Today LCD and plasma TVs emit absolutely no radiation. But even though it's true that sitting too close won't irradiate your child's eyes, it can still cause eyestrain and headaches. That's why all the blinking and flashing (not to mention the noise) can be harmful at close range. Our eyes have to work especially hard when we watch TV in a dark room, so in addition to moving kids away from the screen, it's always better to have the lights on when it's TV time. It's also a good idea to sit up while watching TV -- some kids like to lie on the floor, but that angle can stress the neck and eyes and lead to headaches. Another thing to look out for: If your child regularly sits a foot from the screen, you might want to visit the eye doctor. Glasses may be an easy fix!


There's a third reason to tell your children to get away from the screen, and perhaps it's the most useful of all. Forget radiation, eyestrain and headaches: If a kid is standing with his nose practically on TV, he's blocking everyone else's view. So that's a totally legitimate reason to tell him to back off.
