Do you know anyone with blue or green eyes? No, you don’t, and here’s why: there’s nobody in this world that has blue eyes. According to Dr. Gary Heiting, a licensed optometrist and senior editor of All About Vision, human eyes only have one shade of melanin (what determines our hair, eye and skin color) and it’s brown.

The iris has melanocytes, which are miniature melanin cells, and the more melanocytes in the iris, the darker the eye color. Light is also a factor because melanin absorbs light, so the more melanin you have, the less light will be absorbed.

What this means is that brown-eyed people have more melanin, so they have less light and their eyes look darker. The opposite happens to blue eyed-people. They have less melanocytes, so their eyes absorb less light, so more light is reflected back out of the eye which makes the color seem a lot lighter.

According to the doctor, on the color spectrum, shorter light wavelengths correspond with the color blue. And as for green and hazel-eyed people, well, they have just the right amount of melanin: not too much but not too little.
