How long does it take to get used to contacts?!

Trial is what it means. Its designed to make sure that the lenses are suitable. You will feel like you have something in your eyes for a couple of days - its partly in the mind but your left eye shoudn't go in and out of focus. That implies something is wrong, possibly with teh fit. Speak to your optician about it.

Yeah, that'll happen for a while. Don't be surprised if it takes you a couple of days to fully get used to them, but normally the first day is really weird. They do tend to go in and out of focus, but soon it'll shape thmeselves to your eye and it'll eventually stop slipping. Soon you won't realize they're in there, just be patient! Good luck!

Yes, this will go away within about a week or so.
