Circle lenses are those contacts that make a person's iris look slightly larger. Usually only girls wear them (unless it's some male pop icon or online photo addict). Most wear brown ones, but I've seen blue, and one of my students wore the type with little pink stars. It was really distracting. For some girls, it helps them look cute, like it's supposed to. But for other girls, I think it looks creepy. Sometimes I look at a girl, and I think something is wrong with her eyes, until I get a closer look, and see it's the circle lenses.

By the way, it only looks good on those with Asian eyes. Anyone else who wears them looks super creepy. Maybe that's a good thing for Halloween?
