Does anyone have black colored eyes

So, Which Is the Most Unique? Black Eyes Have you ever seen someone with eyes that seem black as night? Amber eyes are a beautiful honey color! Amber Eyes This beautiful, golden eye color is often confused with hazel. Green Eyes Very little melanin, a burst of lipochrome, and the Rayleigh scattering of light that reflects off the yellow stroma can make for a variety of shades of green.

Violet Eyes Oh, what a purplish blue! Heterochromia This is not a set color, but rather a rare eye condition where either one iris is a different color than the other iris David Bowie!

All human eyes are brown. As the owner of a sparkling set of deep brown eyes, I see no disappointment in the knowledge that all human eyes are in fact a wonderful shade of brown, but for anyone feeling misled or confused, a mix of biology and physics should help explain this reality.

It all comes down to the presence of the pigment melanin, also found in skin and hair, within your eye's iris -- the colored part that surrounds the pupil. Gary Heiting, a licensed optometrist and senior editor of the eye care website All About Vision. Read More. Seeing blue through the brown. Melanin -- made up of melanocyte cells -- is naturally dark brown in color but has the ability to absorb different amounts of light, depending on how much of it there is. The more melanin inside the iris, the more light is absorbed, meaning less light is reflected out, leaving the iris appearing brown.

But when someone has blue eyes, they have less melanin in their iris, resulting in less light being absorbed and more light reflecting, or scattering, back out. When this light is scattered, it reflects at shorter wavelengths along the blue end of the light color spectrum -- leaving you seeing blue. This is why green eyes are so unique. Most of the bronze color tends to settle near the outer edge of the iris, while tiny streaks of brown, green and even gold are seen closer to the pupil.

But like green eyes, hazel eyes tend to be much rarer elsewhere in the world. This is because the hazel pigment level has a unique ability to reflect light in strange ways, giving off the perception of a shifting iris color. About 10, years ago, someone in what is modern-day Europe was born with a genetic mutation causing permanently blue eyes.

Every blue-eyed person today is a distant descendant of this one, ancient human. In the United Kingdom and Ireland, over half of all residents have blue eyes. Worldwide, however, blue eyes are much rarer. Light bounces off their surroundings and turns their eyes into a deceiving, yet breathtaking rendition of purple. If you have brown eyes , you have the most common eye color found in humans. Colors can range from a lighter chestnut to darker hues that almost seem to blend in with the pupil.

Most of these genes play a role in the production, transportation, or storage of melanin. Eyes that are not brown do not have different color pigments.

Instead, they absorb less light because they have less melanin. As a result, they scatter more light, reflecting it along the spectrum of light color. An iris with the least melanin will appear blue.

Those with a little more melanin will appear green or hazel, for example. Nowadays, the AAO note that about half of those living in the United States, and a higher proportion of people in Africa and Asia, have brown eyes. People with brown eyes are less likely to develop eye cancer , macular degeneration , and diabetic retinopathy than those with lighter colored eyes.

Brown-eyed people are, however, more at risk of cataracts as they get older. In the U. Scientists believe that it is possible to trace all blue-eyed people back to a common ancestor, who likely had a genetic mutation that reduced the amount of melanin in the iris. People with gray eyes have little or no melanin in their irises, but they have more collagen in a part of the eye called the stroma.

People with albinism or ocular albinism usually have little or no melanin in the iris. This lack of pigment causes red or violet eyes. As eye pigmentation is important for vision, people with ocular albinism often have problems with their eyesight.
