Tap water and mis-care of contact lenses induces significantly elevated risks of eye infection. Your lottery ticket comparison is apt, since as the article and some other comments here reflect, you are gambling your sight with this attitude. Same one everyone hears from the guy who doesn't wear glasses while he's running a lathe. The difference being, at least that guy can argue his skill reduces his risk of injury.
Would it be wise to stop looking both ways before crossing the street because the first three times you tried it you weren't struck by a car?
No, but if I haven't been struck in the more than 8,300 times I've done it previously, I might have a more lax attitude. Especially when changing habits also includes a fairly major dollar cost.
All that said, after reading a number of different resources, I am considering such a change.
