The color of our eyes is entirely genetic. 70% of people have brown eyes, and it’s considered our species’ natural eye color. Thousands of years ago, mutations changed a number of pigments, like melanin, in some people causing distinct colors.
Blue eyes are common in Northern Europe, and only 2% of people have green eyes. The rarest color, though, is yellow, so consider yourself lucky if you have this color!
Now, some evidence suggests you can gradually change the color of your eyes with what you eat, and although more scientific research is needed, results are encouraging. Here’s all you need to know about it.
