It is said that the eyes are the window to the soul, but new research prove that they are window to your genes. In fact, your iris, the pigmented part of the eye, regulates how much light enters your eye and protects internal organs from harmful UV radiation.

In other words, your eyes depend on your genes combination. When a baby is born, he will have almost no melanin in his stroma, giving him blue eyes. For example, some babies of African or Asian decent are born with blue eyes.
