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.
How many eye colors are there, and why your shade is unique to you. At some point, you've probably wondered what the rarest eye color is. The answer is green, according to the American Academy of Ophthalmology (AAO). Only about 2 percent of the world's population sport this shade.
Brown, which is the most common eye color in the world. Green, which is the least common eye color.
Amber eyes are extremely rare. Most sources say that only about 5% of people have true amber eyes. Coming up with a hard and fast number or percentage, though, is not as easy as you might think—there simply haven't been enough large-scale studies done to quantify eye color prevalence with certainty.
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.
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. For most people, this striking eye color can only be achieved with the help of colored contacts.
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.
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.
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.
The second-rarest eye color is hazel, a mixture of brown and green with golden flecks. About 18% of Americans have hazel eyes, compared with about 5% of the world's population.
Heterochromia is common in some animals but rare in humans. It affects fewer than 200,000 people in the United States.
The rarest skin color in the world is believed to be the white from albinism, a genetic mutation that causes a lack of melanin production in the human body. Albinism affects 1 in every 3,000 to 20,000 people. What is this? People with albinism usually have very pale or colorless skin, hair, and eyes.
Changes in eye color are rare. Sometimes, the color of your eye may appear to change when your pupils dilate. The colors in your environment, including lighting and your clothes, can give the illusion of eye color change.
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.
Eagles – Best Eyes in the Animal Kingdom
One with 20/20 vision can see clearly at a distance of 20 ft. To put that into perspective, an eagle has the visual acuity of 20/5 – meaning that it can see at 20 feet what a human with 20/20 vision would need to be 5 feet away from to see.
Though common in some breeds of cats, dogs, cattle and horses due to inbreeding, heterochromia is uncommon in humans, affecting fewer than 200,000 people in the United States, and is not associated with lack of genetic diversity.
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.
Pink eye is an inflammation of the transparent membrane that lines the eyelid and eyeball. This membrane is called the conjunctiva. When small blood vessels in the conjunctiva become swollen and irritated, they're more visible. This is what causes the whites of the eyes to appear reddish or pink.
The vast majority of people in the world have brown eyes. The second most common color is blue, but people can also have green, gray, amber, or red eyes. Some people have eyes that are different colors than each other.
Scientists at the University of Louisville, Kentucky, have apparently found a hitherto unobserved link between eye-colour and levels of intelligence. Blue-eyed people, they claim, are more studious, more strategic, more focused, and thus out-perform brown-eyed people in exams.
And what would you think is the most attractive eye color? In a website poll of over 66,000 respondents, 20% said green was the most attractive, followed by hazel and light blue at 16%. Brown was far and away voted the least attractive (6%).
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.
The iris has pigmentation that determines the eye color. Irises are classified as being one of six colors: amber, blue, brown, gray, green, hazel, or red. Often confused with hazel eyes, amber eyes tend to be a solid golden or copper color without flecks of blue or green typical of hazel eyes.
Contrary to popular belief, true black eyes do not exist. Some people with a lot of melanin in their eyes might appear to have black eyes depending on the lighting conditions. However, this is not truly black, but a very dark brown.
