Percentage of people with gray eyes in the world. The rarest eye color in the world

According to scientific research and statistics, the most rare color the eye is green. Its owners make up only 2% of the total population of the planet.

The green hue of the iris is determined by a very small amount of melanin. In its outer layer, there is a yellow or very light brown pigment called lipofuscin. In the stroma, a blue or blue tint is present and diffuses. The combination of diffuse tint and lipofucin pigment gives green eyes.

As a rule, the distribution of this color is uneven. Basically, there are a lot of its shades. AT pure form it is extremely rare. There is an unproven theory that green-eyedness is related to the red hair gene.

Why green eyes are rare

In an attempt to find out why green color eye today is a rarity, you should ask for possible reasons to the Middle Ages, namely to the time when the Holy Inquisition was a very influential institution of power. According to her doctrines, the owners of green eyes were accused of witchcraft, ranked as accomplices dark forces and burned at the stake. This situation, which lasted for several centuries, almost completely replaced the inhabitants of Central Europe from the phenotype of the already recessive gene green iris. And since pigmentation is an inherited trait, the chance of its manifestation has decreased significantly. So green eyes have become an infrequent occurrence.

Over time, the situation has somewhat leveled off, and now green-eyed can be found in Northern and Central Europe, and sometimes even in its southern part. Most often they can be seen in Germany, Scotland, Iceland and Holland. It is in these countries that the green-eye gene predominates and, interestingly, is seen more frequently in women than in men.

In its pure form, namely the shade of spring grass, green is still a rarity. Basically, its diverse variations are found: gray-green and marsh.

In Asian countries, South America and the Middle East are dominated dark eyes, mostly .

If we talk about the distribution and predominance of individual shades of the iris in Russia, the situation is as follows: the share of owners of dark eye color accounts for 6.37%, eyes transitional type, for example, brown-green, have 50.17% of the population, and representatives of light eyes - 43.46%. All shades of green belong to them.

The eyes were seen by many as a kind of mirror that opens the veils of the soul. And the most rare color the eye is the ocean of the spirit, as people used to say in antiquity. This old saying is still relevant today. In the rarest eyes, we see pain and mental suffering, in some, boundless happiness and joy, and some do not carry any information at all, the emptiness of the look and indifference to everything in the world. Each individual has his own (different from others) eye color. It, like fingerprints, never repeats, although visually the eyes different people may be the same. But there are those on Earth who have the rarest eye color. It is this point that the article will focus on.

The most common eye color: unexpected data

Through our eyes we look at the reality around us. And it's not a secret to anyone. Eye color begins to form even during the conception of a person, as it is inherited by a certain gene. During the expert scientific research doctors have found that there are only eight of the most common variations in the shades of the eyes. The most common eye color in humans is hazel and brown. Organs of vision with a dark tint are mainly observed in people who constantly live in southern latitudes or in the north (or were born there). And all due to the fact that it is the dark (brown) shade that is able to reflect bright daylight from the sun from the eye. In second place are blue eyes that look like a lake. Statistics: what eye color is the rarest is very small.

What determines eye color?

Even ten thousand years ago, representatives of primitive people on planet Earth practically did not differ from each other in terms of the tint features of the eyes - all of their eyes were brown, sometimes their shade only slightly changed. But due to some change in the body of the primitive representatives of people, something suddenly changed. Genes have gone wrong. There were representatives of humanity with other shades of eyes. Eye color, like all the features of an individual, depends on the triplet, which, by inheritance, passes from parent to child.

What eye color is the rarest among the representatives of mankind?

Many will be very surprised when they find out what eye color is the rarest. It is impossible to give an exact answer. Due to constant evolution, the rarest human eye color has been constantly changing. Of the most ordinary and famous (if you can call it that) eye shades, the rarest eye color can be called greenish and turquoise. Green eyes are the rarest in the world. This statement was made by scientists based on the results of their own research. Although this seems very strange to many. On planet Earth with a greenish tint to the eyes of people, only 2 percent of the total population. It seems to many that this simply cannot be, because green-eyed people are very common. However, this is actually a misconception. Very often gray-eyed people are mistaken for green-eyed because of optical illusions, placement of light and other factors. For example, if a person with gray eyes is on the street, then the shade of the eyes may change. Sometimes gray shades depending on the surrounding person, the spaces take on a blue or green "hint", but in fact they are gray, and this is not the rarest eye color.

In girls on variability gray color Eyes are affected even by make-up. Eyes can be artificially made both green and blue.

Why are there so few people on the planet with "real" green eyes?

There can be many reasons. And it is almost impossible to know which of them is reliable. So, everyone knows that in the Middle Ages all green-eyed girls and many men with a green tint of eyes were considered witches or magicians and burned at the stake. Previously, no one even figured out whether the girl was a witch and whether she was engaged in any "black" deeds. Everyone, even those who had even a hint of a green tint, was burned at the stake. Historians know many cases when even the children of the king were killed in such a brutal way because of the color of their eyes. Many believe that this is why the green tint (color) is currently considered rare. But what is the rarest eye color other than green?

But there is another, more scientific version. Melanin is responsible for the "production" of the green color of the organ of vision in the body. It is he who determines the color of the eyes. In people with a greenish tint in the eyes, there is not enough melanin in the body. And most people have enough of this substance in the body, so they have a different eye color.

A rare eye color (green) is more often found in the fairer sex. And only 5 percent strong half humanity can boast of green-eyed "eyes". The rest are women. Therefore, the question of what eye color is the rarest in men can be answered almost with complete certainty - green. Again, a contradiction arises, because in the Middle Ages, mostly women were killed at the stake. Green-eyed men were burned only after a serious investigation by the Inquisition. Therefore, a contradiction arises, why it is very difficult to meet a man with a rare eye color, that is, greenish. After all, men ("sorcerers") were burned very rarely. No one can explain this contradiction. But many suggest that, most likely, the organs of vision in men with greenish are very rare due to some kind of genetic failure.

In the ranking of the most "green-eyed" countries, the Netherlands is in the lead. More than one second of all people with green eyes live there. About 30 percent more live in Iceland, and the remaining 20 percent in Turkey. Moreover, in the Norman countries, people with a greenish tint characteristic of the eyes can often be found with red curls. Therefore, there appeared a stereotype that all red-haired people most likely have green eyes.

Despite the fact that scientists have identified as many as 8 eye shades, greenish is not included in this list, since it is truly the rarest eye color in humans.

But what is the rarest eye color other than green?

Heterochromia: what is it?

If to speak in simple terms, then heterochromia is an eye disease (it can be either congenital or acquired), in which the organs of vision differ in color completely or partially. Acquired heterochromia may occur as a result of any disease or due to injury.

Experts distinguish two types of heterochromia in humans:

• Full. In this case, both eyes differ in color from each other.
• Partial (sometimes also called sector). Only one part of the eye is different. This type of heterochromia is more common in humans.

Heterochromia is considered a disease of animals (more often cats and dogs), but often its manifestations can be seen in humans. There are many "stars" who suffer from heterochromia. For example, actresses Kate Bossier and Daniela Rua. But what eye color is rare in those who suffer from heterochromia? The question is moot.

The most unusual eye color in the world

It is already known that people are born with pink, reddish, sapphire, blackish and iridescent eyes. But maybe this is just a myth, what is the rarest eye color in the world really? These issues need to be very well understood.

Pink-purple eye shades

Many believe that people with pinkish eyes are seen in Everyday life almost impossible or non-existent. Probably, the majority believes that such shades are betrayed by lenses, and such colors do not exist in nature. In fact, pink eyes are not a myth. Pink (a rare eye color) is considered by most, scientists, the most unusual color eye in the world. Representatives of humanity with pink, lilac organs of vision do exist. Some medical workers It is believed that this eye color is associated with the presence of mutated codons in humans. Such a mutation does not affect vision in any way and is invisible to the whole organism as a whole. Some actually believe that, on the contrary, purple eyes made people happy.

Scientists believe that pink or purple colour the eye could appear due to Marchesani's syndrome. It is not true. Among the symptoms of the disease, there is no exact change in the tint characteristics of the eyes. However, this fact cannot be ruled out. Thus, pink is also, like green, a rare eye color.

red eyes in humans

Almost everyone knows that there are albino people. But no one has seen such unusual representatives of humanity, and even more so with red organs of vision. And all due to the fact that the red-bloody shade of the organs of vision in albinos is rather rare than commonplace. In most albinos, the eyes have the beginnings of brown-brown and blue hues. But red shades of the eyes are less common than others, so red, just like pink-lilac, is a rare eye color.

The effect of bright red shades of the eyes occurs due to the small amount in the body of a substance that regulates the shade. If there is little or no it in the body, through the eyes begin to appear blood vessels, because of which the eyes acquire such an unusual shade.

Sapphire (amber) eyes

Highly strange color an eye that, as it seems to most, cannot exist at all. But if you dig deeper, then the sapphire color of the eyes is a tint from the caret - brown. Sapphire eye color, like red, is a very rare combination. Sapphire (sometimes called amber) eyes are very bright, they have a warm, even golden hue. Eyes that have a sapphire hue are compared with the look of a wolf. Only a few people all over the world have this eye color, so if you meet such a person, then consider that you are very lucky.

Black eyes

Black eyes, like sapphire eyes, can be called a variety of brown. Despite the fact that they are considered the rarest on earth, they are much easier to meet than those described above. The black tint is due to the high concentration of melanin. Most often, dark-skinned representatives of humanity have such an extraordinary color of the organs of vision. This is explained by their black skin color, for which, sometimes, too much melanin is produced. But there are exceptions. Black eyes can also occur in a person with white skin. This is also not uncommon. The black color sometimes changes to brown or grayish when the body's production of a substance that determines the color of the eyes decreases. Sometimes there is rainbow color eye. It combines different shades of eyes.

What is the rarest eye color? The question, despite its simplicity, is quite complex, agree? It can even be considered rhetorical. It is very difficult to give an exact answer to it, because, perhaps, mankind does not even know about some shade of the eyes. The rarest eye color in humans is highly controversial. It is worth considering such a phenomenon as heterochromia. After all, the combination various shades the colors of the organs of vision are, in fact, the rarest eye color.

But at the moment, when asked what eye color is the rarest on the planet, you can answer that red.

Although this is also an ambiguous answer, since the red color of the eyes is caused by blood vessels, not melanin. That is, it is impossible to consider "red" as a color in this case. There is a lot of subjectivity in this issue, for some the color may seem rare, but for some it is common.

What do you think is the rarest eye color?

People with green eyes are fraught with magical mystery and mystery, and therefore have always been considered special (once they were even considered sorcerers and witches). Today, green eyes are the rarest in the world. If you are interested in how many people with green eyes live on the planet, the answer is about 2 percent. Why so few? First of all, due to medieval Inquisition, ruthlessly destroying their owners. Women with eyes of a unique emerald color were called witches and were persecuted in every possible way, and in those days such an accusation was a good reason for being burned at the stake.

Historians claim that about 90 percent of the women burned at the time were young and without children. Moreover, the then superstitious men did their best to avoid contact with green-eyed ladies, who over the years became less and less. Hence the current rarity of the green color - this is a consequence of the deeds of the inquisitors and medieval superstitions.

Note! The eyes are green in people whose body produces a small amount of melanin (this is the pigment that is responsible for the color and color saturation of the iris).

The rarest eye colors

First, let's get acquainted with what colors of the iris are considered the most rare. Unusual make the appearance of the owner memorable, attract the attention of others.

Rarity of green eyes

As noted earlier, this rarity is a legacy of the Middle Ages, when the Holy Inquisition was an extremely influential institution. As a result, green eyes were practically ousted from the phenotype of Europeans. And in view of the fact that pigmentation is a hereditary matter, the chance of green eyes has decreased many times over.

On a note! Over time, of course, the situation improved somewhat, but in a “pure” form, that is, a shade of green grass, the eyes are still very rare. Passing shades predominate - light green, for example, or brown-green.

Also worth mentioning is the uneven distribution of green. There is even a theory according to which green-eyedness is directly related to the red hair gene.

Characteristics of the owners of green eyes

Does eye color affect a person's character?

It is believed that green-eyed people are mostly suspicious and vulnerable. They may look calm, but in reality, inside them is a true hurricane of emotions and feelings.

Among the green-eyed people there are many creative personalities - artists, artists, writers.

Does it affect health?

Deficiency of melanin pigment can lead to different kind eye pathologies and diseases. In addition, problems may arise with the digestive or nervous system. Often there are changes hormonal background provoked by insufficient production of melanocytes. Green-eyed people often change their mood, which, as we have already found out, others may not be aware of.

O personal life people with emerald eyes

They know how to love and care, they are ready to go through any difficulties and trials for the sake of a strong family, without expecting from a partner similar actions. In a word, this good spouses, family men, as well as loving parents.

Friendship and green-eyed

Carriers of emerald eyes are always ready to help and support, even if you have to sacrifice something for this. They give more than they take, they rejoice for their friends from the bottom of their hearts. However, in friendship they are extremely demanding, they need to be treated the same way they treat others. That is why betrayal for such people is a terrible blow, which they most likely will never forgive. And that means the friendship will end.

How many people have green eyes on the planet?

As we mentioned at the beginning of the article, such a rare color of the iris occurs in only 2 percent of the world's population. This phenomenon is especially rare among residents of the Middle East, South America, Asia. As for the most “green-eyed” countries, these include Iceland (about 35 percent) and Turkey (up to 20 percent of the total population). In addition, green eyes can be found among residents of Scotland, Germany and other northern European countries.

On a note! Among Russians, emerald eyes are a rarity. Therefore, if you meet a green-eyed passerby somewhere, you can consider this a good omen.

A few words about heterochromia

Special attention deserves a violation of eye color. For those who don't know, heterochromia refers to the phenomenon when a person has eyes of different colors. This is described in more detail in our article on, and therefore we will be brief. According to statistics, this phenomenon is even rarer than "green-eyed" (only 1 percent of the world's population). Note that people with eyes of different colors were also associated with evil, which is easily explained by a banal fear of everything inexplicable.

Important! Scientists are still arguing which eye color is the most rare. Some consider the green tint as such, others insist on the existence of carriers of purple eyes. Also, color effects at different degrees of illumination are not excluded. In any case, everyone has their own unique color of the iris. Remember this!

Sometimes it happens that the color of a person's eyes changes as rapidly as the color of a chameleon. The only difference is that chameleons do it intuitively and consciously in order to hide, merge with environment. It is in their nature. And in humans, this is due to other reasons that are hidden in the features of the body. The nature of the appearance of such a phenomenon has not yet been studied.

All people with blue eyes have one common ancestor. Scientists have traced the genetic mutation that led to the appearance of blue eyes and established the fact that it appeared 6000 - 10000 years ago. Until that time blue-eyed people did not have.

Most people with blue eyes are in the Baltic countries and the Nordic countries. In Estonia, 99 percent of people have blue eyes.
