What is the rarest eye color in the world? We have the answer!Our eye color is determined by the time we are born. Although we usually have blue or brown eyes in our first few months of life, it soon becomes clear which natural eye color we really have.
Brown, blue or green?
The genes that we get from our parents and grandparents are not only responsible for our eye color. Melanin, which is important for skin pigmentation and natural UV protection, is also involved here. The more melanin there is in our cells, the darker the eye color becomes. A little melanin results in lighter eyes. Blue eyes have evolved from a genetic mutation in which the iris lost the ability to store melanin. Amazing isn’t it?
The rarest eye color is …
A full 90 percent of the world’s population has brown eyes. Everyone among us with blue or green eyes can count themselves among the rare ten percent. Green eyes are the least common. Just two percent of the world’s population have green eyes. People with “iris heterochromia” are also very rare. You have a different amount of pigments in both eyes. Here, for example, the left eye can be blue and the right eye brown, as in actress Kate Bosworth.
