Eye color percentages around the world and what causes eye color [1]
Pigment determines eye color, and a number of genes influence pigment. Brown is the most common eye color worldwide by a large majority.
In this article, we explain what eye color is and what causes it. We also take a look at the breakdown of the proportion of people around the world with each eye color.
The iris surrounds the pupil, which is the small black hole in the middle of the eye that helps control how much light enters it.. Scientists used to think that eye color linked to just one gene and that brown eyes were dominant over blue eyes.
What Is the Rarest Eye Color? [2]
The rarest eye color in the world is likely violet or red—and yes, those colors can occur without the help of contacts. Many factors can influence eye color, including genetics and even certain medical conditions.
But before all that, we’ll look at what determines eye color in the first place.. Genetics and melanin are the two key components that help determine a person’s eye color.
If you have melanin on both the back and front layers of your iris, that causes your eyes to look brown. On the other hand, eyes with no melanin on the front layer of the iris have a lighter appearance because they have less pigmentation
What colour eyes are most attractive? [3]
The eyes are considered to be the most attractive facial feature. Each person’s eyes are incredibly unique, including their eye colour.
No two people will share the same eye colour, shape or appearance.. With that in mind, it can be challenging to choose a favourite eye colour
Celebrities such as Margot Robbie, Marilyn Monroe and Zac Efron are adored by fans for their piercing blue eyes. Perhaps the numerous media productions featuring blue-eyed actors and actresses has influenced this preference.
Green Eyes: Advantages, Disadvantages & More [4]
Green eyes are the rarest color, with only 2 percent of the world population naturally having green eyes. The largest concentration of green eyes is found in Ireland and Scotland, where 86 percent of the population has blue or green eyes.
The color of the eye is determined by a pigment called melanin in the outer layer of the iris. In green eyes, the levels of melanin are lower than in brown or hazel eyes.
In the past, people believed that eye color depended only on a single gene.. Recent genetic research now confirms there are 16 genes responsible for color
7 Interesting Facts About Blue Eyes [5]
Most recent Covid-19 update and what it means for our clinics and patients.. If you have got blue eyes, you might just belong to one of the world’s most exclusive groups without realising it! Since blue eyes are genetically recessive, only 8 percent of the world’s population has blue eyes
The colour of our eyes depends on how much melanin is present in the iris. Blue eyes get their colour the same way water and the sky get their blue colour — they scatter light so that more blue light reflects back out.
The front layer of the iris (called the stroma) is made up of overlapping fibers and cells. For people with brown eyes, some of the cells also have brown pigment in them
10 Facts About Green Eyes – Kugler Vision [6]
“When Irish Eyes Are Smiling” was written as a lighthearted musical tribute to Ireland, and its composers could not have had any idea it would still be popular in 2021. Unsurprisingly, as vision experts, this time of year has us humming this tune
Green eyes are the most rare eye color in the world. Only about 2 percent of people in the world have naturally green eyes
That’s right – strange but true! While green eyes appear that lovely shade of emerald to the outside observer, the irises themselves have no actual pigment. Similar to blue eyes, the color we perceive is a result of the lack of melanin in the iris
The World’s Population By Eye Color [7]
As estimated by the United Nations, the world currently has over 8 billion people, and every one of them is different from one another. The color of one’s eye is perhaps one of the first things people observe when they see each other
Eye color not only affects one’s personality but also reflects one’s ancestry, the melanin concentration in irises, and even one’s current health condition.. Two factors affect the color of one’s eyes: the pigmentation of the eye’s iris and the frequency of light scattering by the murky medium in the iris stroma
The more melanin concentration one has, the darker one’s eyes will be. Likewise, brown eyes have the most amount of melanin, while blue eyes have the least
Green Eyes: Advantages, Disadvantages & More [8]

Countries with the Most Green Eyes 2023 [9]
When people think about common eye colors, they usually think about brown and blue—which are admittedly the top two most common eye colors in the world and are particularly prevalent in certain regions. Some people have hazel eyes, but there are not a lot of people who have green eyes
Green eyes usually result from a genetic mutation that leads to a loss of melanin. Melanin is responsible for skin color, eye color, and numerous other colors throughout the body
Therefore, green eyes are among the most unusual eye colors in the world.. Which Countries Have the Highest Rates of Green Eyes?
Eye Color Percentages: Across the Globe, Effect on Health, More [10]
More than 50% of people worldwide have brown eyes, making brown the most common eye color. Learn more fun facts about eye colors and what they may signal about your health.
Different eye colors are the result of different amounts of melanin.. Today, brown is the most common eye color worldwide.
Then, a common ancestor experienced a gene change that led their descendants’ eyes to produce less melanin.. That may explain why brown eyes are more common in hotter climates throughout Asia and Africa.
Are Green Eyes Rare? What Does it Mean to Have Green Eyes? [11]
From in-depth scientific research and Shakespeare’s Othello to various myths and superstitions, we can’t help but envy this rare and enchanting eye color. We’ll be exploring eye color genetics, green eyes in nature and around the world, plus trivia and theories about green eyes you probably didn’t know!
Most of us come from a long line of dark-eyed individuals whereas people with green eyes are the pearls of eye color—highly desired yet increasingly rare.. As with blue eyes and hazel eyes, green eyes are determined by an array of factors science is still trying to understand.
As with many of our physical characteristics, eye color is thanks to centuries of human mutation.. Although we can’t pinpoint when green eyes entered the gene pool, we do know that eye color is defined by up to 16 different genes

The Most Common Eye Color In The World – BoySetsFire [13]
A recent study has shown that approximately 2% of the world’s population has green eyes. This means that out of the 7.6 billion people on earth, there are approximately 152 million people with green eyes
For centuries, green eyes have been appealing to humans. Because green eyes are influenced by an array of factors, science is still unable to fully explain how they are affected by blue or hazel eyes
Brown and blue eyes are common in infants, but blue eyes are less common. The melanocytes in the eyes can also change their pigments as they grow, increasing the amount of melanin in them
Facts About Your Green Eyes [14]
But in their rarity, there are lots of interesting green eye facts.. – The largest concentration of green eyed people is in Ireland, Scotland and Northern Europe.
There have been 16 genes identified that contribute to eye colour. This means that no matter what colour eyes your parents have, yours can be pretty much any colour.
This is because green eyes are heavily influenced by your environment…. – Green is actually not a pigmentation of the iris at all
What you didn’t know about people with green eyes [15]
LOS ANGELES, CA – Do you know someone with green eyes? You may find their irises beautiful, or even hypnotic, but it turns out that they are even more special than we thought. It’s estimated that only 2 percent of the world’s population have green eyes.
Ever wonder why the sky looks blue? It’s the result of the “Rayleigh scattering”- or the way light is reflected by the air.. Two things determine the appearance of emerald eyes: a low concentration of melanin, which makes them light amber, and the blue-ish effect of Rayleigh scattering in the iris.
The genes that determine eye color are tied to the same genes that form the frontal lobe of our brains- so researchers believe that people with similar eye colors share similar traits.. People with green eyes are said to be intelligent, creative, alluring, and mysterious
What Is The Rarest Eye Color? You Might Be Surprised [16]
What Is The Rarest Eye Color? You Might Be Surprised. One of the strangest parts of Homosapien genetics is our eye color.
Today we’ll talk about the weird and wonderful world of human eyes. Can you change your eye color? And what is the rarest eye color in the US? Read on to find out!
The green-eyed among us only account for 2% of the American population and 2% of the world’s population. Compared to the 5% of blue eyes in the world, 2% is miniscule!
Heffington’s House of Vision [17]
What color are your eyes? Your eye color doesn’t just affect your appearance; it also says something about the concentration of melanin in your irises, your ancestry, and perhaps even your health. Some eye colors are incredibly popular, while others are extremely rare
Melanin is a brown pigment in the eye’s iris, and the type, amount, and distribution of melanin in the iris determines its color. Brown eyes have the most melanin, while blue eyes have the least
So when we say someone has blue eyes or green eyes, we’re really just saying their eyes appear blue or appear green.. Although you might be tempted to proclaim that your baby has blue eyes – and you wouldn’t be wrong – it’s important to remember that the vast majority of babies are born with blue eyes
The World’s Population By Eye Color [18]
Your eye color is defined by the quantity of melanin in your iris. The more melanin you have, the darker your eyes will be
Melanin is a pigment that provides color to your hair, skin, and eyes. The amount of melanin in your iris is determined by your genes and your eye color is usually passed down from your parents.
The shade of brown varies depending on which part of the world you look at. For example, in West Asia, the Americas, and Europe, it is thought that the most common eye color is light brown
What’s the Rarest Eye Color, and Why? [19]
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
Only about 2 percent of the world’s population sport this shade.. “We used to think only one gene determined eye color,” says Julie Kaplan, M.D., a physician at the Center for Personalized Genetic Healthcare at the Cleveland Clinic
The truth, however, is a bit more complicated, Kaplan notes.. About 75 percent of eye color is due to one gene, OCA2

All About Green Eyes [21]
Spring is here, and the color green is popping up more and more everywhere you look. But you probably won’t be seeing too many green eyes
Out of brown, blue, and green, green eyes are the rarest in the world. Only about 2% of the world’s population has green eyes.
That’s because eye color is determined by the concentration of melanin and lipochrome in the iris. Melanin is a brown pigment, and lipochrome is a somewhat yellowish pigment
4 Common Traits Of People With Green Eyes [22]
Studies have been conducted to find connections between certain eye colors and personality traits, and they have been surprisingly accurate.. One interesting bit of information an eye doctor may tell you is that green is one of the rarest eye colors
Previously, it was believed that one dominant gene was responsible for the emergence of green eyes in a child. However, eye doctors are now aware that as many as 16 genes can affect the color of a person’s eyes.
This usually isn’t the case, though, because genetic influences often determine the outcome of a person’s eye color.. More often than not, a child will be born with the same color eyes as one of their parents
What Is the Rarest Eye Color? [23]
The rarest eye color in the world is likely violet or red—and yes, those colors can occur without the help of contacts. Many factors can influence eye color, including genetics and even certain medical conditions.

The Truth About Green Eyes [24]
Did you know that green eyes are the rarest in the world?. Only 2% of the population has this eye color and it is most common in Northern, Central and Western Europe.
The concentration of melanin changes depending on the climate you live in.. Scientists used to believe that your eye colour was determined by two eye colour genes, one from each parent
It is actually more complicated than that and here’s why!. Your eye colour is determined by several genes that control melanin production in your iris
Which Eye Colors Are the Rarest? [25]
Green is the rarest eye color of the more common colors. Outside of a few exceptions, nearly everyone has eyes that are brown, blue, green or somewhere in between
The color of our eyes tends to play a big part in our self image and, in some cases, can be a genetic throwback to your family tree. It can be hard to even imagine what you’d look like with a different eye color.
The results are listed below, ordered from most rare to most common.. In addition to being the rarest eye color among Americans, green eyes are the most attractive, according to 66,000 people who voted in our survey.
Eye color [26]
Eye color is a polygenic phenotypic character determined by two factors: the pigmentation of the eye’s iris[1][2] and the frequency-dependence of the scattering of light by the turbid medium in the stroma of the iris.[3]: 9. In humans, the pigmentation of the iris varies from light brown to black, depending on the concentration of melanin in the iris pigment epithelium (located on the back of the iris), the melanin content within the iris stroma (located at the front of the iris), and the cellular density of the stroma.[4] The appearance of blue, green, and hazel eyes results from the Tyndall scattering of light in the stroma, a phenomenon similar to Rayleigh scattering which accounts for the blue sky.[5] Neither blue nor green pigments are present in the human iris or vitreous humour.[3][6] This is an example of structural color, which depends on the lighting conditions, especially for lighter-colored eyes.
The genetics and inheritance of eye color in humans is complicated. As of 2010[update], as many as 16 genes have been associated with eye color inheritance
The genetics of eye color are so complex that almost any parent-child combination of eye colors can occur.[10][11] However, OCA2 gene polymorphism, close to proximal 5′ regulatory region, explains most human eye-color variation.[12]. Eye color is an inherited trait determined by multiple genes.[13][14] These genes are sought by studying small changes in the genes themselves and in neighboring genes, called single-nucleotide polymorphisms or SNPs
Learn Why Green Eyes Are So Unique! [27]
They are also extremely unique and very rare! It has been estimated that only 2% of the world’s population have true green eyes. To give you an idea of just how special green eyes are, consider this factoid
Going by the math, this means only 140 million people have some shade of green as an eye color. There are only a handful of celebrities who have green eyes and even a smaller number who are male.
FYI: green eyes can express in several shades, including hazel, emerald, jade and blue-green. When you take into account the different variations of this color, including some people with hues of brown, the number of people who can be classified as having green eyes jumps from 2% to 8%.
An Overview of Eye Color Percentages Across the World [28]
While no two people have the exact same color, shape or size eyes, an overview of eye color percentages across the world does offer some eye-opening insights into worldwide trends.. It probably comes as no surprise that the most common eye color around the world is brown
In fact, about 10,000 years ago, researchers believe we all had brown eyes. Although, there are several shades of brown ranging from dark chocolate to light brown.
Light brown shades are most often seen in West Asia, Europe and the Americas.. However, only 8 to 10 percent of individuals actually have blue eyes.
This Is the Rarest Eye Color in the World [29]
What determines the shade of your peepers? Experts weigh in on the rarest eye color in the world—and the genetics behind it.. It’s said that our eyes are the mirrors of our souls, so it makes sense that eye color is often romanticized
In fact, no two people in the world have the same color eyes. And if you’ve ever wondered what the rarest eye color is, you’re not alone.
While genetics play a role in all of the above, one gene in particular has a large hand in determining eye color. And here’s an interesting fact: When it comes to the rarest eye color in the world (spoiler, it’s not blue eyes), only about 2% of the population have it—the same percentage of redheads worldwide.
