Well, yeah, I can definitely feel it once it's in backwards. The difference is that I know when it's inverted before putting it in my eye, despite the fact that I can't really see the lens clearly, especially without my glasses on.

Or if you wear Acuvue 2 lenses like I do, the small "123" printed on the lens guarantees that you can't screw it up. :)

Acuvue 2s are supposed to be put in your eyes in such a way that, if the "123" were large enough and in a darker color that didn't match the white of your eyes, it could be read correctly (i.e., not backward) by another person taking a close look at your eye. (That is, if you hold it up to a light and the "123" appears backwards to you, the side nearer to you is the one that goes on the surface of your eye.)

when inside-out, the edge flares out slightly, when rightside-in the curvature of the lens at the edge is maintained. This edge can be felt, making the lens slightly less comfortable, which I suspect is your intuition saying: "hey dipshit, your contact lens is in backward".
