i think i was near sighted when i was younger. so i started wearing glasses and it helped. i dont think its a "natural way" though but thats my 2 cents
I don't know of any natural ways to correct nearsightedness--truthfully, I don't think there's much that you can do about being nearsighted, except to wear glasses--I've been wearing glasses since I was a freshman in high school--and like r0llinstoned said, it may not be a "natural" remedy, but it works!
