FWIW, I regularly wear the B&L disposables for about 2-3 months at a time, and so far I haven't had a problem in the 2 years since I switched to them. I do take them out and clean them every night (with my vision being as bad as it is, I've always had to do this, even with extended wear lenses) but my eye doctor told me that as long as I did that and washed hands etc. etc. I should be fine as long as I pitch them at the first sign of discomfort. I've yet to actually get a pair to that point, though-if I don't pitch them every 2 months or so, they'll expire! Which reminds me, I should have pitched this pair at the beginning of February-oops... :Q
