Oakley has sectoral heterochromia, and it's so pretty!
"In anatomy, heterochromia (Greek: heteros 'different' + chroma 'color') refers to a difference in coloration, usually of the iris but also of hair or skin. Heterochromia is a result of the relative excess or lack of melanin (a pigment). It may be inherited, or caused by genetic mosaicism, chimerism, disease, or injury.
Heterochromia of the eye (heterochromia iridis or heterochromia iridum; the common incorrect form "heterochromia iridium" is not correct Latin) 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 (hyperchromic) or hypopigmented (hypochromic). In humans, usually, an excess of melanin indicates hyperplasia of the iris tissues, whereas a lack of melanin indicates hypoplasia."
The problem is that most of the time, you cannot see that he even has it. When he was only a few months old then you could spot it, but only in the right light. As he's gotten older his eyes have gotten darker and it's been harder to see them. I used to think that he would have green eyes with his chunks of brown, but now I am very curious as to what they are going to look like when they full develop and really get their color. Most sources say by one year old their color will be really pronounced, but all of our children have really gotten in their eye color around a year and half or later.
All or most of these photos, his face is super exposed, so that you can see his eyes -- I'm still trying to get just one really really awesome perfect photo of his eyes like you can see them in real life!
