How long to develop myopia?!
Question: How long to develop myopia?
Answers:
A very good question. Current research says you most likely inherit the tendency to become myopic if you do certain things. In other words, two people doing the exact same thing will have different results depending on their genes. Very very few are hard-wired to become myopic. Reading, by the way, is not a big problem, but avoiding the outdoors is a problem.
How long it takes to happen probably varies with your genes also, somewhere between a few months to a year for most people.

Reading books does't cause myopia. It is either genetic or congenital.
