Well, I did too--I started wearing glasses at around age 4. Books and TV would certainly contribute as well--as I understand it, "nearpoint stress" is the main cause of myopia. The eyes are tuned for scanning the horizon for faraway threats; we're naturally more far-sighted. Focusing your eyes closely causes strain, where your eye muscles must contract the lens constantly. Your eyes accomodate this stress by keeping the lens in a contracted position, and by lengthening the eye. |
