They say the eyes are the windows to the soul.

But just how special are yours?

You're probably familiar with the same old shades, but believe it or not,

there are people with silver, violet, or even multicolored eyes out there.

Let's explore some of the rarest eye colors spotted in humans.

You're listening. You're listening to be amazed.

You probably know at least one person with blue eyes, but as it stands, only about 8 to 10

percent of the world's population can say they have a pair of blue blinkers.

A study conducted by the University of Copenhagen in 2008 revealed that all blue-eyed people

are descendants of the first light-eyed humans who emerged in southeastern Europe around 10,000

years ago. Eye color is determined by the amount of melanin in your iris, which is made up of

the epithelium, the back of the iris, and the stroma, which is positioned in front. While the

epithelium contains dark brown pigments, the stroma can sometimes be totally devoid of melanin

making it translucent, which is the cause of blue eyes. Interestingly,

natural blue pigment doesn't exist. It all has to do with the way light enters the eye. While

melanin absorbs light and presents it as brown, blue eyes scatter light back into the atmosphere

in what is known as the Tendal effect, similar to how the sky sometimes appears blue.

A 10,000-year-old genetic mutation affecting the OCA2 gene created a switch which can turn

off the production of melanin, meaning the clear stroma presents as blue.

Blue eyes are even less common in people of African American descent,

and in such cases the iris can often appear as a piercingly beautiful ice blue.

Now, 79% of us have brown eyes, but there is one rare variation which only 5% are lucky enough to possess, known as amber eyes. People with truly amber eyes have a distinctly
