On a tangential note, I've always wondered about this sort of idiom. 20/20 vision is the equivalent of a 100 IQ -- it is equivalent to that of a "typical human". Perfect vision would be 20/ε (you can see at 20 feet what an ordinary human could only see from an infinitesimal distance), and mundane glasses will often correct vision past 20/20.
It seems like such a low bar for hindsight to meet.
