I am 14 and I have -5 in one eye and -3.5 in other. I really want to reverse my myopia. I want to do Lasik when I reach 18 but people say I should wait till I am 25. But I don't want to wait, I am afraid my eyesight will become worse. I have heard that eye exercises increase eyesight but is it temporary? Even if I can't reverse my myopia can you guys tell me methods to avoid worsening my eyesight till I am 20? I am trying to spend less time on screen that's one thing.
