A limbal ring is a dark ring around the iris of the eye. It is a dark-colored manifestation of the corneal limbus resulting from optical properties of the region.
It has been suggested that limbal ring thickness may correlate with health or youthfulness and may contribute to facial attractiveness. Some contact lenses are colored to simulate limbal rings.
