National Different Colored Eyes Day was established to celebrate this beautiful variation in eyes, and to break some of the mystery surrounding it. There are many things that can cause heterochromia, some of them being nothing more than a genetic trait present from birth, others being caused by disease or injury. There are three different types of heterochromia, each one being identified by the degree to which the heterochromia exists and how it manifests.
You see, heterochromia can be complete, where each eye is a complete different color from the other, and appropriately enough this is known as Complete Heterochromia. In partial heterochromia, a portion of the iris is a different color from the other, and in what has to be our favorite manifestation of heterochromia, especially when occurring in both eyes, is when the inner ring of the iris is a different color than the rest of it.
We even have multiple records of it occurring throughout history “She was a very beautiful woman… She had dark, dark brown eyes, but each eye had a purple ring to it, about a quarter of an inch of purple around these dark brown eyes.” These words were spoken of Baroness Rozsika Edie von Wertheimstein, who was known to have central heterchromia.
