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]
Limbal rings become less pronounced with age, thus darker rings imply youthfulness and are considered attractive.[2] Some contact lenses are colored to simulate limbal rings.
