Myth: Sitting too close to the TV is bad for the eyes.
Fact: Although parents have been saying this ever since TVs first found their way into our homes, there's no evidence that plunking down right in front of the TV set damages someone's eyes. The American Academy of Ophthalmology (AAO) says that kids can actually focus up close without eyestrain better than adults, so they often develop the habit of sitting right in front of the television or holding reading material close to their eyes. However, sitting close to a TV may be a sign of nearsightedness.
L'argument de l'écran est faux. Une des hypothèses du pourquoi beaucoup de gens souffrent de myopie est :
Myopia experts haven’t reached a consensus about how exactly to slow the rising tide of nearsightedness. But one Australian researcher found that kids could maintain healthy vision by spending three hours per day in light of 10,000 lux or more--the same amount of light a person would see wearing sunglasses on a bright day. (For comparison, a well-lit classroom is usually no more than 500 lux.) Many researchers agree that kids who spend more time outside will maintain good vision for much longer, plus the physical activity could stave off obesity and improve mood. The work has sparked a number of East Asian countries to start public health campaigns designed to get kids outside.
