Circle contact lenses are soft contact lenses with a limbal ring that is larger than the patient's visible iris. The look is very dramatic and is favored by anime enthusiasts for making people look more doll or anime character-like. The Etafilcon A® lens (in photo) is a 1-day replacement lens that is currently the only FDA-approved circle lens in the US.
