If you had X-Ray vision, do you think you could help but using it all the time?
Check out Superboy #98. Clark just sees some kid on the street and exposes him to some X-Ray radiation. Not that Ultra Boy isn't doing the same thing, but that just proves my point that much more:
Why Ultra-Boy's disguise consists of preppy on the top and baseball uniform on the bottom is anyone's guess.
But see? Here we go again:
And I'm not saying I blame anyone. I'd be using it all over the place. I'd call it "X-Ray vision" like Superboy does, and not "Penetra-Vision." "Penetra-Vision" sounds like the name of a studio that makes porn movies. (Hi, Googlers!)
I've said it before, and I'll say it again:
I just don't think it's necessary to have that many statues of Superboy.
Yes, that is a foolproof method of identification. Because no one can wear a uniform that doesn't belong to them. That would be dishonest.
