However, 10-15% of Caucasian eyes change to a lighter color as they age, as pigment in the iris changes or degrades.

Heterochromia iridium (two different-colored eyes within a single individual) and heterochromia iridis (a variety of color within a single iris) are relatively rare in humans and result from increased or decreased pigmentation of the iris.

That's right, just 2 percent of the world's population is lucky enough to have 'em, according to World Atlas. Compare that to other eye colors.

With only two percent of the world's population having green eyes, it's definitely rare! Pretty purple eyes naturally occur because of a lack of pigment, but are very rare.

Only about 2 percent of the world's population has green eyes. Green eyes are a genetic mutation that produces low levels of melanin, but more than blue eyes. As in blue eyes, there is no green pigment. Instead, because of the lack of melanin in the iris, more light scatters out, which make the eyes appear green.

This is known as ocular albinism. People with ocular albinism usually have blue eyes. In some cases, the iris (the colored part of the eye) has very little color so a person's eyes might look pink or reddish. This is caused by the blood vessels inside the eye showing through the iris.

Between 8 and 10 percent of people worldwide have blue eyes. Blue eyes are most common in Europe, especially Scandinavia. People with blue eyes have the same genetic mutation that causes eyes to produce less melanin. The mutation first appeared in a person living in Europe about 10,000 years ago.

And they may appear to “change color” from gray to blue to green depending on clothing, lighting, and mood (which may change the size of the pupil, compressing the colors of the iris). Green is the least common eye color, but it is found most frequently in northern and central Europe.

Eye color is determined by genetics. The eyes can naturally change their color as a response to the iris expanding or contracting in the presence of light or as the iris ages. This results in the eyes gradually becoming darker or lighter in color.

And when you meet a red head with blue eyes, you are looking at the rarest colour combination of all for human beings. Around 17 per cent of people have blue eyes, and when combined with 1-2 per cent having red hair, the odds of having both traits are around 0.17 per cent.

They're the components in your eyes that help you see light and colors. ... But some evidence exists that there are people who have four distinct color perception channels. This is known as tetrachromacy. Tetrachromacy is thought to be rare among human beings. Research shows that it's more common in women than in men.

The Darker Side of Change Heterochromia, a condition in which a person's eyes are two different colors, can be an inherited condition or caused by trauma, which could shake loose some of the melanocytes, making the eye appear lighter or darker. ... But in all cases, changing eye color is very, very rare, says Dr. Schwab.

About 5 percent of people around the world have this rare eye color. Amber eyes are uncommon, but can be found throughout the world. Amber is a golden yellow or coppery color without specks of gold, green, or brown. The iris contains mostly the pigment lipochrome and not much melanin.

However, while your eye may look momentarily different, your actual eye color isn't changing. Hazel eyes can often appear to change colors more than other eye colors. ... If you have brown eyes, you can have laser surgery on your eyes to remove the melanin and make them appear blue.

When does eye color change? The most dramatic eye color changes will probably occur when your child is between the ages of 3 and 6 months old. By that point, the iris has stashed enough pigment so you'll be able to better predict what the final hue will be.
