Turns out, every single human being has brown eyes.
Yup, according to a licensed optometrist who writes for All About Vision, there are no such thing as blue eyes.
Apparently, the perception of the colour of our eyes is all down to the pigment melanin level, also found in our hair and skin, in the iris.
“Everyone has melanin in the iris of their eye, and the amount that they have determines their eye color,” Dr. Gary Heiting told CNN.

“There’s really only (this) one type of pigment.”
Proving further that all eyes are brown, melanin is also naturally, dark brown.
So why do we have blue, green and brown eyes? Melanin has the ability to absorb different amounts of light.
The more you have in your iris, the more light is absorbed which means less is reflected out, leaving your eyes brown.

In terms of blue eyes, you will have less melanin, meaning your eyes soak up less light and therefore more reflecting.
When the light is scattered out, it reflects at shorter wavelengths along the blue end of the light colour spectrum.
Complicated stuff, right?!
Green and hazel eyes fall somewhere in the middle of the spectrum.

“It’s an interaction between the amount of melanin and the architecture of the iris itself,” added Heiting.
“It’s a very complex architecture.”
This also explains why all babies are born with blue eyes as they are yet to develop all their melanin.
