These People's Genetic Conditions Really Make Them Unique

A Boy Rocking His Heterochromia

We’ve already explored heterochromia a few times in this article and discussed its different types. But what actually causes this unique eye condition? The primary cause is genetic factors, such as genetic mosaicism, which occurs when changes happen during cell division in the embryo. This process affects the formation of the iris, leading to different eye colors. Interestingly, heterochromia can happen to anyone, regardless of their background

But genetics isn’t the only factor. Environmental damage to the eyes or certain medical conditions can also trigger changes in eye color. For example, injuries, inflammation, or diseases like Horner’s syndrome might play a role. So, is heterochromia just a rare quirk, or does it tell us more about our health? While it’s often harmless, it’s always a good idea to consult a doctor if you notice sudden changes in eye color. After all, our eyes can reveal more than we think!
