Heterochromia iridum

What are the odds of a dog and his owner both have two different color eyes? Bud Lammers discovered one such couple and we present his wonderful portrait of them right here.

Heterochromia of the eye (heterochromia iridis or heterochromia iridum) is of two kinds. In complete heterochromia, one iris is a different color from the other. In partial heterochromia or sectoral heterochromia, part of one iris is a different color from its remainder. Eye color, specifically the color of the irises, is determined primarily by the concentration and distribution of melanin. The affected eye may be hyperpigmented or hypopigmented. In humans,usually,an excess of melanin indicates hyperplasia of the iris tissues, whereas a lack of melanin indicates hypoplasia.

Photographers note: None of the eye colors are photoshopped.

Some other famous people who have two different color eyes are David Bowie, Mila Kunis, Virginia Madsen, Jane Seymour, Elizabeth Berkley, Dan Aykroyd, Kate Bosworth, Kiefer Sutherland and Christopher Walken.

Isn’t the Internet a wonderful thing?
