You're either trolling, or you didn't think this through. People can do all kinds of potentially dangerous things for an extended period of time without negative consequences (heroin, football, diet pills, etc). Extrapolating anything based solely on your own survival is weird.

Moreover, the infection being discussed in this article is incredibly rare - and contact lenses are generally quite safe - so the fact that neither you nor anyone else commenting here has been exposed to it shouldn't be surprising. That you've made it 7 whole years without going blind isn't some vindication of your own hygienic patterns, or an indictment of hers.
