I have encountered people who do that. They're called hipsters, and they make me want to punch them in the face. They always wear those stupid-ass giant nerd glasses which, to me, is like wearing a giant sign over your head (or on your eyes, in this case) that says "I AM A GIANT ASSHAT. PAY NO HEED TO MY ENTIRE EXISTENCE, FOR IT IS WORTHLESS IN EVERY ASPECT." But, then again, that's what I feel about every aspect of this ludicrous hipster culture. Them damn whippersnappers dang-nabbit and so on and so forth.
On a side-note, it's always funny when people who don't need glasses ask to wear mine. One of my friends almost falls over whenever he tries.
