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.[1]

It has been suggested that limbal ring thickness may correlate with health or youthfulness and may contribute to facial attractiveness.[2][3] Some contact lenses are colored to simulate limbal rings.
