OK, about 6 or 7 years ago, Dateline or one of those news shows did a story on Bauch and Lomb and how the disposable are exactly the same as the regular "non-disposable". Sort of the same gimmick as saline solution. The little bottle is made up of the same stuff as the big bottles, but the little bottle is 4X as much price wise.
So, I buy disposables off the internet at 1-800-contacts. I just use them until they happen to get a break in them or become uncomfortable. I take them out at night and clean them periodically. I save lots of money this way. I've been doing this for about 8 years and my eyes are fine. The secret is to not leave them in overnight, this is what is "bad" for your eyes. You eyes need oxygen from the front of your eye, and with the contact on there, the oxygen is blocked. Eventually your eye will grow "feeder" vessels (your eyes will look bloodshot) because they cant get oxygen from the front.
