What is the most popular eye color. Blue eye color. Brown eye color is the most common eye color

Eye color in humans is inherited by one of many genes. From the moment of conception, a person is predetermined to have one or another shade of the iris. However, even scientists cannot say with 100% certainty what eye color a child will have. What affects the shade of the iris and what rare eye colors do people have?

What color are people's eyes: four main shades

People's eye colors are completely unique. It is known that the pattern on the iris is as unique as human fingerprints. There are mainly four colors of the iris - brown, blue, gray, green. According to statistics, green is the rarest color listed. It occurs in only 2% of people. There are only 4 primary colors, but there are many shades of them. IN exceptional cases The human iris can be red, black and even purple. These are the most unusual shades that the iris acquires after birth; they are extremely rare in nature.

Is it possible to determine what eye color a child will have?

After birth, the baby's eyes are usually light green or dull gray. After a few months, the tone of the iris changes. This happens thanks to melanin, which accumulates and forms the color of the eyes. The more melanin, the darker the iris. The color determined by the genes appears at approximately one year old, but it will be finally formed only by 5, and in some cases by 10 years. The intensity of eye color, that is, the amount of melanin, is influenced by genetics and nationality. No geneticist can predict with absolute certainty what exact eye color a child will have. However, there are some patterns that allow us to assume what a person’s eyes will be like. These patterns can be seen using examples:

If mom and dad have blue eyes, then the probability of having a child with the same iris shade is 99%. 1% remains for green, which is the rarest of the four main ones.
If one parent has blue eyes and the other has green eyes, then there is a 50% chance that the child will have green or blue eyes.
If dad and mom are green-eyed, then the probability of having a baby with a green iris is 75%; 24% are cases of a baby being born with blue eyes, 1% - with brown.
If one of the parents is blue-eyed and the other is brown-eyed, then their children will be brown-eyed in 50% of cases. 37% of children from such unions are born with blue eyes, and 13% with green eyes.
Children with brown-eyed parents will also be brown-eyed in 75% of cases. They can have green-eyed children with a probability of 18%, and blue-eyed children with a probability of 7%.

It is worth taking into account that a child’s blue eyes may subsequently become sky blue, gray-green – emerald, and brown – black. This is almost impossible to predict. Actually, this is the basis of the uniqueness of the shade of the human iris. Sometimes she has an unusual color from birth. There are completely rare shades, found in only one person in hundreds of thousands. Let's make a list of the most unusual eye colors.

The most unusual eye color in the world. Top rare eye colors in people

The first place in the list of “The rarest eye color” is violet. This shade is obtained by mixing blue and red tones; few people have seen people with purple irises. As geneticists note, violet eyes are a similarity to blue ones, that is, they are a variant or pigment of blue color. It is believed that purple eye color is found only among the people of North Kashmir in the world. The legendary actress Elizabeth Taylor also had lilac eyes. Varieties of purple shade include ultramarine, amethyst and hyacinth.

Sometimes a lilac iris can be a symptom of pathology. In Marchesani syndrome, which is characterized by abnormal development of the eyes and limbs, the iris may take on a purple hue.

Purple can be considered a great rarity, it is rather beyond comparison. Then the green tint rightfully takes first place in the ranking of eyes of unusual colors. Only 2% of the world's population has it. In this case, the following patterns are observed:

Green-eyed ones are more common in Northern and Central Europe, including Germany, Belgium, the Netherlands, Norway, Finland, Iceland and Scotland. In Iceland, approximately 40% of people have green eyes. In Asia, Africa, South America it is almost impossible to meet green-eyed people if we're talking about about the indigenous people.
Women have green eyes three times more often than men.
Many green eyed people have white skin and red hair.

The most famous owner of green eyes is Hollywood actress Angelina Jolie. Her iris has a dark green tint. Actress Tilda Swinton has bright emerald green eyes, while Charlize Theron's irises are a calmer, light green color. Among men with green eyes, one can remember Tom Cruise and Clive Owen.

Another rare color is red. Most often, albinos have red eyes, although with albinism the iris is usually brown or blue. The iris becomes red when the melanin pigment is absent. Because of this, eye color is determined by shining through the iris blood vessels. If the red tint mixes with the blue tint of the stroma, the eyes may take on a magenta color, which is closer to violet.

Amber eye color, which is a type of brown, is also very rare. Amber eyes are usually bright, clear with a very strong golden tone throughout the iris. Varieties of amber color include golden green, reddish copper, tan and golden brown. True amber eyes, which may somewhat resemble the eyes of a wolf, are practically never found in nature. However, shades of amber are also quite beautiful and rare.

Fifth place in the top unusual eye colors is black. It is, in fact, another variety of brown. The black iris contains a lot of melanin, the amount of which determines the intensity of the color. Thanks to its saturation, the black tint almost completely absorbs the rays of light falling on the iris. This type of eye is found mainly among representatives of African peoples. In Caucasians, it is less common, but it is more common than purple, green and amber eyes. A famous owner of black eyes was the British actress Audrey Hepburn. Varieties of black include slate black, obsidian, pitch black, dark almond and jet black.

The eyes are also very rare different color. This physiological feature called heterochromia.

Eyes of different colors

Heterochromia is a fairly rare phenomenon. It occurs in only 2% of the world's population. It occurs due to a lack of melanin in the iris of one eye. Congenital heterochromia develops approximately six months after the birth of a child, when pigment begins to be produced. If it is distributed unevenly, the eyes take on different shades.

Most often, congenital heterochromia is observed in women, although scientific explanations no to this. Men's eyes also come in different colors, but much less often. But their heterochromia manifests itself in more unusual shape.

Types of heterochromia:

Full. Often in this case, one eye of a person is brown and the other is blue. Anatomically, the organs of vision do not differ from each other. They have the same size and visual acuity.
Partial. With this form of heterochromia, the iris of one eye is colored in different shades. It can be divided into halves, quarters, or have wavy color borders. As a rule, partial heterochromia is observed in children aged two to four years. Subsequently, melanin is distributed evenly. If this does not happen, it is necessary to get checked and identify the presence of pathologies.
Central. This form is characterized by the appearance of rings around the pupil. This phenomenon is somewhat reminiscent of the rainbow effect, when one iris has two or more rings of several colors. There are no more than a dozen such people all over the world.

Heterochromia, which has genetic background, manifests itself after birth. The acquired form occurs as a result of injuries and diseases, for example, Fuchs syndrome. This disease is an inflammation choroid and irises. The syndrome usually affects one eye. One of the symptoms of the disease is lightening of the iris. There are others, more rare pathologies accompanied by a change in the color of the iris. Among them:

Posner-Schlossman syndrome is a type of uveitis, that is, inflammation of the iris and choroid;
Horner's syndrome is a disease associated with lesions nervous system and manifested in the organs of vision;
Pigmentary glaucoma is a pathology in which pigment separates from the iris and enters other parts of the eye;
Iris melanoma - malignant tumor, which is usually dark brown in color.

All these pathologies are characterized by a change in eye color.

Chameleon eyes

Another rare phenomenon associated with iris color is chameleon eyes that change color. A change in the shade of the iris can occur as a result natural causes and under the influence of external factors. Natural emotions include emotions (stress, fear). External factors— air temperature, atmospheric pressure, room lighting. Chameleon eyes can become lighter or darker, depending on the influence of these factors. Such changes are temporary and not always noticeable.

Have you ever seen a person with amber color eye? What about a person with green or red eyes? No?! Then, you will be a little surprised if you find out that everything is not some myth that has been brought forward for centuries, but is quite real. Although there are not many people with such rare eye colors, they still exist.

However, there is nothing sci-fi or extraordinary about this. Everything is quite natural, since he depends mainly on the pigmentation of the iris.

What is the iris of the eye: light, psycho-emotional and hereditary components

The iris of the eye is an almost impenetrable thin and mobile diaphragm of the eye with a pupil in the center, located behind the cornea (between the posterior and anterior chambers of the eye), in front of the lens. The color of the iris depends mainly on the amount of coloring pigment called melanin (responsible for color and affects the shade of skin and hair), as well as on the thickness of the eye shell itself.

There is a direct dependence of the color of the eyes on the reaction of the pupil to light, that is, the pupil reacts to light. When the pupil is constricted, the pigments of the iris are concentrated and the eyes begin to darken, and when the pupil is dilated, on the contrary, the pigments of the iris are dispersed and the eyes begin to lighten. In addition, the emotions that a person experiences also affect the size of the pupil, and, depending on the psycho-emotional state, his eye color may be different.

Eye type. U different people These are combinations of combinations of four main factors:

blood vessels of the iris have bluish tint: blue, light blue, gray;
content of coloring pigment (melanin) in the iris: brown, black;
the content of certain substances in the iris (often associated with liver diseases): yellow;
bloody iris (only in case of albinism): red.

If you correlate these factors with each other, the result will be a certain color. For example, swamp is a mixture of brown and blue, green is a mixture of yellow and blue, and so on.

Top 5

What color do you think the eyes are? Honestly, it is difficult, or most likely impossible, to determine since there are so many different shades of eye colors, some of which are very rare and very rare.

Below is a list of 5 varieties of eye colors (from the rarest to more or less natural), which are less common, which makes them, in turn, more unique compared to the rest.

1. Purple eye color: hoax or reality!

It turns out that purple eye color is. There is an opinion that it is impossible to have purple eyes by nature. This is not entirely true. Purple eyes come from mixing red and blue shades.

From a genetic point of view, violet eyes are a similarity to blue eyes, namely a reflection, pigment or variant of the color blue. However there is scientific facts, which prove that people living in remote and high altitude areas of North Kashmir have purple eye color. However, this unique eye color is very rare.

Varieties of purple eye color: ultramarine (bright blue), amethyst and hyacinth (blue-purple).

2. Green eyes: gene for red hair

Green eye color is second only to violet in rarity. This type of eye color is determined Not big amount coloring pigment, melanin, which in combination with the light brown or yellow pigment lipofuscin (distributed in the outer layer of the iris of the eye) gives green coloring to the eyes. T

This coloring is usually uneven with many different shades. There is an opinion that the red hair gene may play a role in the formation of green eye color. Purely green color- an extremely rare phenomenon (only 2% of the world's population has green eyes). Carriers of this color are found mainly in Central and Northern Europe, less often in the southern part of Europe. According to a study of the adult population of Holland and Iceland, green eyes are much less common in men than women.

Varieties of green eye color: bottle green (dark green), light green (light green with yellowish tint), emerald green, grass green color, jade, green foliage colors, emerald brown, colors sea wave(blue-green).

3. Red eye color: albino eye

Red eyes are called albino eyes, although more than usual, since blue and brown eyes are more common. This rare phenomenon is associated with the absence of the coloring pigment melanin in the ectodermal and mesodermal layers of the iris, and therefore eye color is determined by the blood vessels and collagen fibers of the iris. Sometimes, but very rarely, the red color of the eyes, when mixed with the blue color of the stroma, can turn into violet (magenta).

4. Amber Eye Color: Golden Eyes

Amber color is essentially a type of brown. These are clear bright eyes with a pronounced warm golden color. True amber eyes are very rare, and due to the monotonous light yellow-brown coloring, the eyes have a rather exotic appearance, like the eyes of a wolf. Sometimes, amber eyes can be characterized by a reddish-copper or golden-green tint.

Varieties of amber eye color: yellowish brown, golden brown.

5. Black eye color: high concentration of melanin

Black eyes, although considered rare, are much more common than all previous ones. Due to the fact that the black iris has a very high concentration of the coloring pigment melanin, the light that falls on it will be almost completely absorbed. This type of eyes is common mainly among the Negroid race: in the Eastern, Southern and South- East Asia. In addition to the black iris, the color eyeball may have a grayish or yellowish tint.

Varieties of black eye color: bluish black, pitch black, obsidian color, pitch black, dark almond, thick black.

Congenital eye defects or heterochromia

Heterochromia is a congenital or acquired (due to disease or injury) eye disorder in which there is a different color of the irises of a person’s eyes, that is, a person has eyes of different colors.

Heterochromia is divided into two types:

complete (eyes are completely different in color);

partial or sectoral (part of the eye has a color difference from the rest of the iris).

Although this phenomenon is more typical for dogs and cats, people have cases too heterochromia, such as the famous American actresses Daniela Ruah and Kate Bosworth.

Video - why eyes are so different

Purple, red, green, black, amber! There are very few people with such eye colors, but this in no way diminishes them, but, on the contrary, makes them increasingly unique and extravagant. Violet– this is the color of purity and psychic energies, green is the color of youth and vitality, amber– strength and endurance, black- mysticism and magic, and red– ambition and passion.

Do you have a rare color? Which have you seen most unusual eye color?

Eye shade affects features in personality behavior, appearance. Individual makeup, wardrobe items, and jewelry are selected to match the shade, which will further influence taste preferences and style. When making a first impression of an interlocutor, people take into account his eye color. Usually a rare and extraordinary eye shade is remembered more than a simple one.

The color is determined by the corresponding gene, so from the moment of fertilization the shade will already be laid down in the child. Scientists estimate about 8 existing shades which are the most common. But there are people living on the planet who have a rather rare shade. Have you ever seen a person with a congenital purple or red tint? This happens, it’s not a fairy tale. Sometimes it happens that people have unusual eyes, let's consider such situations.

Common color

The most predominant shade is still brown. Only the Baltic countries do not fall under this definition, since people live there a large number of people whose hair color is light, as a result of this many residents are blue-eyed.

Nature has its own principles, so people with a brown tint predominate in sunny areas planets located in southern latitudes. Brown has a peculiarity - the more bright sun there is in the place where people live, the darker the brown colors they have. After all, only the shade with the predominant dark color can protect the iris from blinding sun rays.

Another unusual factor is that among almost all the peoples of the Far North, where low temperatures, there is also a brown tint. Here the dark pigment will protect the eye socket from light, blinding light. Therefore, it is not easy for light-eyed people to look outside in winter.

Brown-eyed coloring is associated with Venus and Sun. It is believed that he got his ardent and hot character from the sun, and lightness from Venus. This may be true, but such people are also described as cold in their relationships with strangers, selfish and self-loving. It is accepted that they quickly become attached to a person, but their affection can disappear just as quickly. Brown-eyed people do not have difficulties communicating with close friends; they can always support and find a topic for conversation. They like to communicate, but they talk mainly about themselves. It is also important for them to be listened to, while they themselves are not good at listening.

Experts decided to survey people about eye shades, and were amazed that people with brown eyes Many respondents feel a sense of trust and confidence. Showing photos of people who have had their eye color changed is all the same larger number percent of people made a choice in favor of brown eyes. This is due to the fact that brown-eyed people have a special type of appearance that gives a pleasant feeling. So, if you put several people with different eye colors next to each other, more people will still choose the brown-eyed one.

Common color for Northern residents

The majority of the population living in northern Europe has a grayish-green tint. It is this color that is more common, but when you see a face with clear green or clear gray eye, this will no longer be uncommon. By medical indications the iris is colored this way due to blood vessels, located in the shell, which make it bluish.

And also with this, a small amount of melanin penetrates into the iris, which is too little to color the eye dark or brown. Ultimately, you get eyes that will rearrange depending on emotions and processes occurring in the body, like chameleons.

The character of people who have a gray-green tint is characterized as hot-tempered and slightly cocky. Although such aggression can only be observed by external signs, but inside they are very soft, trusting of people and capable accept all difficulties that befall their lives. An unusual factor is that such people can live next to a person for whom they do not feel special love and feelings, but at the same time respect his spiritual qualities. This color harmonizes well with any range of casual clothing and looks good with makeup in dark shades.

Blue eye color

Today, blue-eyed people cannot be considered a rarity, although we do not see them on every corner. Most people with this color are found among European peoples. For example, nations such as Estonians or Germans are blue-eyed.

Gray and blue colors appear predominantly due to the saturation of the membrane with melanin. There are different shades: from mousy light gray to rich blue. They change depending on the type of lighting and the emotional state of their owner.

When meeting blue-eyed people, be sure that you are facing a person who is creative by nature, who has constant changes in mood. Most often such people have distinctive features before the people around him by his character and appearance. They have contradictory qualities, for example, they begin to feel sad during general fun. These people prefer constant changes in handmade, have inconsistent choices in their decisions and point of view. But behind all this, truly important qualities can be hidden: love, sentimentality, high feelings for loved ones, and they can give everything for the sake of their relatives.

First of all, the shade due to number coloring matter in the iris of the eye. It is at the moment of birth that the child has bright eyes, but sometimes brown-eyed newborn babies also happen. Over time, the color begins to change. The formation of color development ends at the age of 13. But with old age, it begins to noticeably fade, which is determined by a decrease in the amount of pigment in the shell.

In most cases, color is associated with the color of hair and skin. In the classical view, persons who have dark skin tone and dark hair , are located and dark eyes, for example, African and Asian nationality. But fair-haired and fair-skinned people have blue or blue eyes. These include Swedes and people of the Slavic group.

Rare green eye color

Unfortunately, green eye color was previously considered by people to be a sign of magic and mystical power. It was believed that people with this color were endowed with magical powers and magical abilities. Scientists are still wondering why the green color became so extraordinary. Total about two percent Of the billion people living throughout our planet, they are green in color.

A large number of opinions on this topic come to the answer that in ancient times people with this eye color were exterminated. Girls with green eyes suspected of witchcraft and burned at the stake. Women were considered outcasts, excluded from society.

As a rule, there are several times more women with green eyes than men. But if in ancient times most girls in at a young age ended up at the stake, then what kind of continuation of the family could we talk about? However, the men themselves were afraid to be near such girls, fearing the gift of witchcraft.

In green-eyed people, the coloring substance melanin is produced in very small doses. And also the green tint is more common among women, as a result of which it is quite difficult to meet a man with a green eye tint.

If we consider the most populated countries with green-eyed inhabitants, then there are more of them in Iceland and Holland. Although experts have formed a group of eight main shades, green is so unusual that it was not even included in this group.

Swamp eye color

Swamp eyes are those in which there is a combination of several colors and it is impossible to accurately name the color of the eyes. The color shade is characterized as somewhere between gray and brown. This color is also the most rare color eye.

Sapphire eyes

We almost never see a face with violet eyes in everyday life. There is a version that purple arose due to transformation processes. But it does not have a significant effect influence on visual acuity and safe for him. From the point of view of genetic science, violet color is just one of the variants of blue eyes, or a reflection of pigment in darker colors. There is evidence that some residents in one area of Northern Cashmere have this unusual sapphire coloration.

In medicine, there is a theory that violet can become a factor in the appearance of a disease such as Marchesani syndrome. Although changes in eye color are not specified in the description of the disease, characteristics of Marchesani syndrome include short stature, underdevelopment of certain bones, and various diseases eye. So we can firmly say that nature gave these people rare and unusual beauty, which sets them apart from millions of people on Earth.

Red eye tint

In another way, red-eyed people are called albinos. This shade occurs when there is absolutely no melanin in the iris. Because of this, the iris turns red under the influence of blood vessels and various fibers. IN in some cases When red and blue are combined, purple is formed.

Amber eye color can be called one of the options brown color . This is a light, bright shade that has warm notes. Truly amber eye color can be seen very rarely in everyday life, so it is considered unique and can be compared to the eyes of some predator.

Black color

This color is not that rare. The color occurs due to the high concentration of melanin in the lining of the eyes. Therefore, when light hits the iris, it will be completely absorbed. Most of all he common among Africans.

All colors are universal indicators of a person’s personality and character. Each of us should be proud of our eye color, as it is truly the most unique and beautiful.

Attitudes towards a person are often based on how they look. But there are things that have little to do with it. Eye color is given to us from birth, and there are those who have it the rarest. And sometimes they say a lot about the character of the owner, which is sometimes explained quite logically.

It turns out that the rarest eye color on earth is violet . There is hardly anyone who has seen the owner of such eyes. This color appears due to a rare mutation called "Alexandria origin". Immediately at birth, such a patient has the most common color. It changes after 6-10 months.

2nd place.

Red color very rare. It occurs in people and animals with a certain disease. Also included is White color hair.

3rd place.

Pure green color eyes are very rare. A population study was conducted in Iceland and Holland, which showed that they occur more often in women than in men. The softness of associations is understandable. There is a lot of it in nature - the foliage of plants, the color of some crawling animals, and the color of human organs.

4th place.

Rare are different colored eyes . Scientifically, this phenomenon is called heterochromia. The color may include splashes of other colors, or simply both eyes are colored differently. A rare phenomenon, but original looking.

5th place.

Blue color the eye is considered a variety of blue. But it is somewhat darker and is quite rare.

6th place.

Yellow considered a variety of brown, but is rare. It is generally accepted that such people are endowed with magical abilities. They say they have telepathic abilities. They usually have an artistic nature. If you have no bad thoughts in your mind, then communicating with people with this eye color will bring real joy.

7th place.

Hazel eye color - this is the result of mixing. Lighting can affect its hue, and it can be golden, brown, or brownish-green. Hazel eyes are a common occurrence.

8th place.

Despite the fact that the owners blue eyes They consider themselves to be in the elite category of society; there are quite a lot of them in the world. They are especially common in Europe, in its northern part and the Baltic countries. Among the population of Estonia, owners of blue eyes are found in 99% of the population, in Germany - 75%. It is generally accepted that its owners are softer and less psychologically developed than, say, those with brown eyes. They are considered a variety gray, although the latter is much more common. In Russia it occurs in almost 50% of cases.

9th place.

Very common in the world black eye color . Its owners usually belong to the Mongoloid race, in South, Southeast and East Asia. Sometimes the color of the pupil and iris merge, which creates the feeling of a completely black eye. Given the prevalence of people living in these regions, black eyes are not uncommon. IN in this case, the black iris is different high concentration the coloring pigment melanin. Accordingly, the color falling on it is absorbed. The color is also found among the Negroid race. The color of the eyeball sometimes has a grayish or yellowish tint.

10th place.

Most common brown eye color . His warm personality speaks volumes about his origins. It has a very large number of shades, ranging from light to dark brown. Its owners are found in the following countries:

Asia,
Oceania,
Africa,
South America,
Southern Europe.

Very bright and warm eye color. It has a sea of shades from light to dark brown. It looks quite strange, and, undoubtedly, impressive.

Eyes are the mirror of the soul. You can drown in their bottomless depths, you can pin them to a place with your gaze or captivate your heart forever... Masters of words often use such epithets. And indeed, sky blue eyes enchant, bright green eyes enchant, and black eyes pierce through. But how often in real life can you meet green-eyed people, and what eye color is the rarest? Read on for answers to these questions.

What eye colors are there?

In reality, there are only 4 pure eye colors - brown, gray, blue and green. But the mixing of colors, pigmentation, the amount of melanin, and the network of blood vessels together create many shades. Thanks to this effect, there are people with light brown, amber, black and even red eyes.

This is theoretically possible, but practically no one has seen it yet

Scientists who study what determines eye color, the heredity of this issue and possible mutations have experimentally determined that theoretically people with violet eyes should live on Earth.

Purple, from a genetic perspective, is a pigmented version of the color blue. Except scientific theories There is evidence that in the remote corners of North Kashmir on the Hindustan Peninsula there are residents with real lilac eyes. Unfortunately, this is only oral evidence, not confirmed by photography or video, so skeptics are cold to such a statement.

However, the eyes of Elizabeth Taylor, the popular actress and queen of Hollywood, had an unusual purple colour. This is clearly visible in the film “Cleopatra”, where she played brilliantly main role. And these could not be colored lenses, because their production began in 1983, and the film was released in 1963. Although the play of light and shadow coupled with skillful makeup sometimes works wonders...

If we discard the hypothesis about the existence of people with violet eyes on earth, then we can safely say that green is the rarest eye color on the planet. Only 2% of the world's population possess it. In this case, the following patterns are observed:

The vast majority of green-eyed people live in central and northern Europe, mainly in Scotland, Holland, Germany, Belgium, Norway, Iceland, and Finland. If in Iceland 40% of the total population have green eyes, then this color of the “mirror of the soul” cannot be found in Asia or South America;
In women, this eye color is 3 times more common than in men;
there is a direct relationship between green eyes and skin and hair color. Green-eyed people are almost always white-skinned and most often red-haired. During the Inquisition, green-eyed, red-haired women were considered witches and burned at the stake;
If mom and dad are green-eyed, then the probability of having a child with the same eye color is 75%.

If only one parent is green-eyed, then the probability of having the same baby is reduced to 50%. Interestingly, if one parent has brown eyes and the other has blue eyes, they will never have a green-eyed child. But if both parents are blue-eyed, then the child’s eyes will probably be green, and not blue color. That's genetics!

The famous poetess Marina Tsvetaeva had eyes of a beautiful emerald shade. Demi Moore and the beautiful Angelina Jolie have irises of the rarest natural green color.

Amber or gold

These colors are varieties of brown eyes. They have a monochrome yellow tint or a mixture of golden and light brown tones. Such exotic wolf-like eyes are very rare. Their amazing color is due to the presence of lipofuscin pigment.

Blue lake – blue magnet

In third place in terms of prevalence are blue eyes. They are most common among Europeans, especially in the Baltic and Northern European countries. For example, almost all Estonians (99% of the population!) and Germans (75% of the population) are blue-eyed.

This shade is quite common among residents of Iran, Afghanistan and Lebanon.

Gray and blue are shades of blue, due to the greater saturation of melanin in the iris. Grey eyes capable of changing tonality from light gray, mousey to the rich color of wet asphalt, depending on the owner’s mood and lighting.

It is known that only about 6 thousand years ago a mutation occurred at the gene level, as a result of which the first child with blue eyes was born.

Blue-eyed people have a greater need for sex and pronounced reproductive functions.

Brown-eyed

The most common eye color is brown. Depending on the saturation of melanin in the iris, the eyes can be light or dark brown, almost black. Scientists are 100% sure that 10 thousand years ago, all people on the planet had brown eyes.

A variety of brown shade is black. Black-eyed inhabitants of the Earth are most often found in Asia and Africa. Scientists know that dark color skin causes dark eye color. Negro with blue eyes - a rare phenomenon on the planet.

Pathologies

Deviations from the norm are red and multi-colored eyes. In the first case, the cause is albinism - a congenital absence of the coloring pigment melanin in the body. In the second - heterochromia, a congenital or acquired pathology. Since ancient times, people with with different eyes attributed magical abilities.
