WARNING: Don't Use ReNu Saline Solution
I can't believe I almost missed this. In case you did too, read the article from CNN and check out the official statement from Bausch & Laumb about ReNu with moistureLoc potentially being linked to a rare eye infection that damages corneas. Several people have had to have corneal transplants as a result. There is also a generic brand they make but I did not have time to find those specifics.
Thankfully I don't use my contact lenses as often any more, but I did use ReNu and I did leave my lenses in at night, which increases the risk, but everything seems to be ok.
