He has a rare birthmark on his eye
Most of us have a birthmark somewhere on our skin. Birthmarks may be all over our bodies, but we did not know that we could have them on our eyes! Yes, there is such a thing as an iris nevus, which is essentially an eye freckle, and here it is.
According to recent studies, this genetic mutation affects roughly 6 out of 10 people, making it far more frequent than we think. Besides, the appearance of this birthmark can be influenced by factors such as sun exposure, but they are usually harmless. It is like a tattoo on the eye. Cool.
