This American woman and her little son conquered the Internet with their unusual eyes

Elizabeth Tyler, 35, from Ohio, and her son, one-year-old Liam Mexus, have extraordinary eyes: half black, half piercing blue. This feature is due to heterochromia - a rare mutation, which, however, does not affect health in any way. Thanks to their unusual appearance, Elizabeth and Liam became social media stars.

35-year-old Elizabeth Tyler and her one—year-old son Liam Mexus are the owners of heterochromia, a genetic anomaly that causes a person's eyes to acquire a different color from birth. This anomaly is quite rare and usually leads to the fact that each eye of its owner has its own color.

But at Elizabeth and Liam are an even rarer case: they have different colors combined in one eye. Elizabeth's eyes are both brown and blue at the same time, and Liam's one eye is bright blue, and the other is half brown, like his mother's.

Most often, heterochromia manifests itself only in the color of the eyes, although sometimes its owners have violations of skin pigmentation — the so-called "piebald skin" with areas completely devoid of pigment. But at Elizabeth and Liam did not find any other manifestations of the anomaly.

Usually heterochromia is not inherited, but in Elizabeth is a different case: her father, sisters and brothers are all owners of heterochromia.

Elizabeth's son also inherited the family distinction.

Elizabeth is not at all shy about her exotic features and is happy to publish photos on social networks — both her own and her son's.

According to Elizabeth, she likes to think that unusual eyes set her apart from the crowd, that she is unique. She says that by publishing her pictures, she wants to show everyone: there is nothing wrong with being different from others.

Subscribers often ask Elizabeth about her condition, and she takes the opportunity to explain to everyone what heterochromia is and how it occurs.

Elizabeth has five children, but only Liam inherited her peculiarity. Why this happened is a mystery: doctors still do not know everything about the mechanisms of heterochromia, because it is very rare in humans. Heterochromia is found much more often in animals, primarily in cats and dogs.
