We tend to describe the pupil as though it's its own actual separate part of the eye. It's almost strange to think about the fact that in reality it's just a hole in the Iris and not a "thing" at all. - eviltoast

For example, why do we say “Your pupils are dilated”. They aren’t. It’s the iris aperture that is dilated.

    I didn’t think so? When I say Iris, I mean the colored ring. When I say pupil, I mean the hole. When I say asshole, I mean the ring, not the hole. I can’t remember ever wanting to refer to the actual hole. Maybe “gape?”
