La télé et les yeux

Je vous le dis, ces légendes urbaines sont vraiment encrées profondément dans notre subconscient :

So when you or your children are practically sitting inside the TV, are your eyes suffering? Dr. Lee Duffner, spokesperson for the American Academy of Ophthalmology, responds in his professional opinion: "Hogwash. You won't cause any physical damage to your eyes."

Actually, your eyes have specialized muscles that control the shape of the eye lens (for focusing) and your eye movements (to keep the eyes moving together). If an object is closer to the eye, as it is when you are close to the TV, the muscles controlling the lens automatically change, or accommodate its shape to bring the object into proper focus.
