I've tried the extended wear a couple of times. I can't wear them even a single night. I use the
daily disposable. Wear them once toss them out. No cleaning, no problems in years and years of use. The only thing I don't like is that I can't fall asleep watching TV with them in. I always carry a few extra pairs so there is no worry if I lose one at the pool or some such.
One thing you can look into, an eye specialist I saw suggest I get shunts. Most people who can't wear extended wear have dry eyes. The shunts are essentially little straws inserted into your tear ducts to open them up.
