I have never heard about that fact that if your eyes go bad again it couldn't be fixed anymore with glasses or otherwise. That seems ridiculous. My brother had eye laser surgery, last year, and they fixed his -8 (yes ... -8) eyes pretty much to near perfection. And he has a 10 year guarantee (this is belgium btw), so if his eyes go bad again in this period, they'll fix them for free again. He's very very happy he did this.
