Genetic cause does not imply genetic cure.

I remember reading something contradicting this statement and my own research into possible myopia causes seems to indicate environmental factors as the cause (but not conclusively). As a myopic person that has no one in my extended family suffering from it, I am very confused as to the possible causes.
