Where a person (usually a guy) is barely worth attention with his glasses on, but when he takes them off you notice how very hot and attractive he is.

Guy: I got contacts.
Girl 1: Aha..... (distracted)
Girl 2: (whispers) Clark Kent Syndrome.
Girl 1: Yeah, totally....

Clark Kent Syndrome 

Based off Superman, it's the inability to notice that someone wearing glasses and that person not wearing glasses are the same person.

Kyle: Tim? Is that you?

Tim: Yeah.

Kyle: Oh. I almost didn't notice you with your glasses on.

Tim: Yep. That's Clark Kent Syndrome for you.
