You would definitely feel it if you had a contact inside out---it hurts! Did they show you how to tell if they were inside out by looking at them? You actually don't look at it straight on...I hold mine up on my fingertip at eye level and look from the side view of the contact. If it makes a perfect cup it's the right side, if the cup has a flat "lip" around the edge it's inside out. I have worn contacts for a long time, and love them. When I went for my yearly exam last month my vision hadn't changed, but I was out of contacts, so the doctor gave me a trial pair of the ones I'd been wearing. My right eye was so blurry---I thought he'd made a mistake about my prescription...I put up with it for a couple of days, then I couldn't stand it anymore, so I just put in a new contact in my right eye and that fixed everything. Sometimes they can get a tiny rip that you can't see but that can cause blurred vision. As far as the case, I've never heard to rinse it and close it up while you're wearing your contacts...I've always heard to leave the case open so it can dry out...hmmm...I'm curious what others have been told... Anyway, congrats on the new contacts---you'll love them once you get used to them!
