Having made the transition from soft to hard contact lenses about a year ago, I cannot IMAGINE how uncomfortable these would be. I mean, soft contacts feel like a dream in your eye, but hard contacts are a terrible tickling and/or painful feeling that you eventually learn to block out. These lenses are based off of some pretty hardcore special hard contacts, and I would imagine that you wouldn't be able to just pop them in and out -- you'd probably have to train yourself to be able to wear them over a few months. Just thinking about it makes me cringe.
