limbal ring

Women with thick, dark limbal rings in their eyes have also been found to be more attractive.

The term may also refer to the limbal rings around the iris.

Some eyes have a dark ring around the iris, called a limbal ring.

A limbal ring is a dark ring around the iris of the eye.

Some contact lenses are colored to simulate limbal rings.

The result is the appearance of a bigger, wider iris, with a limbal ring, and create an illusion of large eyes.

Limbal rings become less pronounced with age, thus darker rings imply youthfulness and are considered attractive.

The explanation given is that because the ring tends to fade with age and medical problems, a prominent limbal ring gives an honest indicator of youth.
