So far so good, but I have only worn them for 6 hours per Dr. orders. I'm supposed to increase wearing them by 2 hrs. a day until I have worn them ~16 hrs. or so. I couldn't really feel the right, but noticed the left a bit. Yes, I need near and far correction. They are disposables and I was told that they should last ~ a month/pair. The only info. I found on the web seemed to state they were 2 week wear, but I never saw the vial and the girl that walked me through everything didn't seem very sure about exactly which contacts I was dispensed.
