A while back, an anon on here, confessing that he used to have a serious drug problem and would therefore know, said those eyes are often the sign of someone doing drugs. He added that they don't have to be illegal drugs, either; that there are some prescription drugs that will result in the same bug-eyed defect.

And I wouldn't know. This is stuff we were never supposed to notice, let alone know anything about. And there's been a LOT of that going around, lately.
