Black Eyes. There's an eye disorder known as aniridia which makes the eye appear to have “no iris.” In truth, there is a small ring of iris tissue, but it is so small and the pupil is so large that it can look like the eyes are completely black. It is due to a chromosome mutation.
While some people may appear to have irises that are black, they don't technically exist. People with black-colored eyes instead have very dark brown eyes that are almost indistinguishable from the pupil. In fact, brown eyes are even the most common eye color in newborn babies.
Blue is the second most common and brown tops the list with 45% of the U.S. population and possibly almost 80% worldwide. Black is not an eye color. While some eyes may look black, they're either just a very dark brown or have large pupils (more on this below).
Nobody has black eyes, however dark brown eye color is more dominating than blue eye color. Contrary to common perception, real black eyes do not exist. Depending on the lighting, some persons with a lot of melanin in their eyes may seem to have black eyes.
Green is considered by some to be the actual rarest eye color in the world, though others would say it's been dethroned by red, violet, and grey eyes. Green eyes don't possess a lot of melanin, which creates a Rayleigh scattering effect: Light gets reflected and scattered by the eyes instead of absorbed by pigment.
We found that green is the most popular lens colour, with brown coming in a close second, despite it being one of the most common eye colours. Although blue and hazel are seen as the most attractive eye colours for men and women they are surprisingly the least popular.
Only 1% of people have pink and pale red eyes; they are typically albinos. Albinism happens when there is a problem with one of the genes inherited from the mother. Like red eyes, heterochromia is rare and effects less than 1% of the population.

EYE COLORS: The most common eye color is Brown . The rare colors are Blue and Green. More rare still are Black, Amber and Violet. The rarest of the rare is Red.
Permanent changes to eye color can be achieved through iris implant surgery, corneal pigmentation, and laser eye color change. Iris Implant Surgery is a procedure that inserts a prosthetic iris into the eye. It was originally developed to treat iris defects such as albinism and aniridia.
After a few days, the black and blue bruises will fade to yellow or green as the blood is reabsorbed into the body. Black eyes usually take up to 2 weeks to heal.
Unbelievable as it may seem, the answer is yes—natural purple eyes do exist. Purple eyes are also commonly referred to as “violet eyes,” as they are typically a light shade.
Although the name "black eye" would indicate otherwise, the eye itself is usually not injured. Many black eyes heal on their own in a few days. A black eye can be a sign of a more serious injury, such as a hyphema (bleeding in the eye). However, a black eye can be a sign of a more serious injury.
Did Elizabeth Taylor have violet eyes? These days, thanks to colored contact lenses, anyone can have violet-colored eyes . Taylor didn't come by her purple peepers that way; the first tinted contact lenses weren't commercially available until 1983. Taylor's eye color was the real deal.
Red/Pink Eyes
Two major conditions cause a red or pinkish eye color: albinism and blood leaking into the iris. Although albinos tend to have very, very light blue eyes due to a lack of pigment, some forms of albinism can cause eyes to appear red or pink.
To have black hair, one must have genetically inherited this gene from both of their parents, and brown hair is achieved when it is inherited from one parent. This gene is demographically common, as 90% of the total world population carries this gene.
Honey brown, hazel, green and grey are the best color choices for contact lenses that complement Indian skin tone.
Complete heterochromia is definitely rare — fewer than 200,000 Americans have the condition, according to the National Institutes of Health. That's only about six out of every 10,000 people. It's currently unknown how rare central heterochromia is, but we do know that it isn't quite as rare as complete heterochromia.
The hazel eyes, which are a variant of brown eye colour, are found in Indian subcontinent, but their occurrence is comparatively lesser than brown or black eyes. Our pedigree study suggested that the hazel eye colour inheritance does not follow the Mendelian inheritance patterns.
True purple eyes are exceedingly rare. Less than 1% of the world's population has them, making them rarer than blue, hazel, amber, grey, or green.
Blue is the second most common eye color globally, with an estimated 8 to 10 % of people having blue eyes. A majority of these people are of European descent, however, Black people can be born with blue eyes even though it's pretty rare.
Blue Eyes. Originally, all humans had brown eyes. Some 6,000 to 10,000 years ago, a genetic mutation affecting one gene turned off the ability to produce enough melanin to color eyes brown causing blue eyes.
Brown eyes are the most common: Over half the people in the world have them, according to the AAO. In fact, about 10,000 years ago, all humans had brown eyes.
This rare condition only affects about 3% to 7% of people. If you're born with it, your liver doesn't make enough of an enzyme it needs to process bilirubin.
