i'm assuming by pupil you meant iris, since most contacts aren't going to change your pupil color, although i have seen one person with a pair of red contacts that didn't have a pupil hole (they weren't sclera, but also covered the pupil. from what i heard, it was a bit more difficult to see).
i have these red
contacts and they are really really nice and bright (and i mean bright !! these are really great for cosplay. the picture on that link if you scroll down is pretty accurate) and they came in my ridiculously strong prescription of -5.00 (right) and -4.50 (left).
