My contact lens technician recommended switching from Acuvue 2 to Advance two months ago. I agree with the previous replier; the lenses are more comfortable, but a little more difficult to handle. I haven't had problems putting them in, but I find them more difficult to take out at night (but not so difficult that I wouldn't recommend a switch). At times, I also find it hard to determine if they're inside-out. Overall, though, I am very pleased.
