When meeting a new interlocutor, the first thing we pay attention to is the eyes, their shape, color. The shades of the iris can be varied. There is little romance in the formation of eye color: it is formed depending on the amount and distribution of melanin in the iris.
In addition, the color of the iris depends on a person’s heredity, race, climatic conditions, and place of residence. The structure of the iris is unique and can be compared to fingerprints. An interesting feature in the formation of eye color is that in the first years of life, the color of the iris can change.
In medicine, a limited amount is isolated possible options eye shade. Basic colors of the human rainbow:
The formation of the shade of the iris depends on: the density of melanin, the structure of the fibers.
Blue eye color, which predominates among other shades, is a mutation in genetic code, which originated more than four thousand years ago in northern Europe. It is formed due to the peculiarities of the structure of the fibers of the iris, that is, their density.
Green color, in turn, is formed by mixing yellow and brown pigments, which directly form this shade. As a rule, owners of green eyes are residents of Southern countries and Britain. Distinctive feature the formation of this shade is the “saving” of melanin - in other colors of the iris there is much more of it.
The gray shade of the eyes was formed in almost the same way as blue. However, in a situation with gray eyes, the density of the fibers of the iris is much greater, because of this the blue color turns into gray. It is worth noting that gray eye color is not very common. A person can have this shade regardless of his place of residence: from Africa to the North Pole.
IN in rare cases There are eyes that have an exceptional, beautiful, unusual amber hue. People with this eye color are considered practically unique.
The swampy shade of the eyes appears when individual colors are combined and, as a result, the color of such eyes changes slightly depending on the lighting. A rare eye color option.
The situation is completely different with brown eyes; they are much more common than others. Regardless of what part of the world, what hemisphere, country, city you are in - you can always meet owners brown eyes.
Blue eye color is formed by the special structure and arrangement of the fibers of the iris; they are arranged in such a way that when sunlight passes through the iris, the eyes are reflected blue. It is worth noting that there is no blue pigment.
The black tint of the eyes was formed by saturating the iris with brown pigment “to the limit”, so that the light passing through it is not scattered through the fibers, but is absorbed into them. In its structure and location, the fibers of the black iris are very similar to the structure of brown eyes.
Since the era of ancient sages, there has been an opinion that eye color has a certain relationship with a person’s character traits and his destiny.
In the Middle Ages green color the eye spoke of the woman’s connection with evil spirits, and could be the reason for her execution.
Our ancestors paid attention to eye color Special attention. There has long been a popular saying: “A black eye, a lively look, a habit like a wolf.”
Currently, scientists around the world believe that people with light eye shades are more susceptible to negative influence environment, have weak immunity.
Psychologists say that:
However, one should not measure everyone “with the same brush”; during the scientific study of the iris, it turned out that by definition there cannot be an exclusively pure eye color.
Billions of people inhabit our planet, and they are all, of course, different. Scientists have proven that there are no people in the world with exactly the same eyes. Each one has a unique unique color and iris pattern. When getting to know a person, we first of all pay close attention to his eyes. After all, as you know, eyes are the mirror of the soul. They can both attract and repel. Even before a person is born, nature determines what kind of eyes he will have. And it all depends on heredity and the amount of melanin in the body.
Genetics have calculated that there are 8 main colors of the iris. Most people have brown eyes. And how many owners of rare color range? Let's try to figure out together which eye color is considered the most unique.
The smallest number of earthlings have it. It is widely believed that this color can be caused by certain pathologies or diseases. But this is not true. Geneticists believe that purple eye color comes from mixing blue and red, being a shade of blue.
According to researchers, the largest number of people inhabiting the Earth with similar eyes live in the mountains of North Kashmir. Despite this fact, purple is the least common eye shade.
It's interesting that famous star cinema Elizabeth Taylor had eyes purple. However, as facts show, in fact she had them blue-gray, and purple shade provided light on the film set.
I would just like to add that medicine interprets the appearance of violet eye color very convincingly. Albinism, in which the human body lacks melanin, causes the appearance of a red iris in most cases. But when mixed with red Blue colour(blue collagen), a purple tint appears. This shade may be a consequence hypersensitivity albinos, as a result of which light penetrates the iris, causing a rare purple tint.
Only 2% of the world's inhabitants have it. It is also called the “red color”. Largest quantity Melanin is the cause of “green eyes”. It is impossible to see pure green color; basically, we see numerous shades of this tone.
Owners of this rarity can most often be found in Europe. There are few people left with green eyes.
It is also called “golden” or tiger. Eyes of this tone create an impression of warmth, clarity and divinity. In fact, similar phenomenon is caused by the presence of lipofuscin in the body.
Interesting!Owners of the brindle coloring are very artistic and always think creatively. They are credited with the ability to read other people's thoughts. It is very pleasant to communicate with such people, of course, if they are not up to something bad.
Black color is inherent in representatives of the Negroid and Mongoloid races. Babies among these peoples are born with pronounced black eyes. The structure of the iris is very close to brown, but the amount of melanin in these cases is so huge that the light is simply completely absorbed.
People with black eyes have strong energy and a restless disposition. They are passionate in everything they do. They are often hasty in their decisions and rarely consider the consequences of their actions.
This list also includes people with red eyes, who are often called albinos. Although this is not entirely correct. This phenomenon can most likely be considered a pathology, since there is practically no melanin in the body of these people, and therefore the color is determined by blood vessels and special fibers.
What happens? The color of the most important human sense organ is determined by chemicals located in the human iris. It doesn't matter what eye color we have or how rare it is. The main thing is the desire to achieve something in life and do everything that depends on us to achieve our goal.
Why do people different colour eye? Human eye beautiful and unique - it is specific like a fingerprint. Therefore, it is not surprising that many are so obsessed with the issue of eye color and its influence on people’s character.
“The eyes are the mirror of the soul.” Is this really so and what do we know about them?
Eyes are sensory organ, through which we receive more than 80% of the information from the outside world. This is possible due to the presence of photoreceptors in them:
Rods help people navigate in the dark, and cones respond to light. To what color are the retinal cones selectively sensitive? Cones are sensitive to blue, green and red wavelengths of light. It is this color spectrum that is the basis for our color perception.
Everyone's eye color is different and ranges from very light shades to very dark ones. Although genetics plays a dominant role in determining the color of the iris, like many other genetic characteristics, it is not so simple.
So what determines a person’s eye color? It is generally accepted that children inherit iris color from their parents. In fact, color inheritance is more difficult process– polygenic. This trait is influenced not by one gene, but by several. Moreover, this is not the only factor that shapes color.
To find out what eye color a person has, just look at the color of his iris. It is determined by the content and size of the pigment fibers responsible for color - melanin.
At birth, children have not yet produced a sufficient amount of this color pigment, so many newborns have grey-blue eyes(they are also called “milk”). Gradually, melanin accumulates, and the baby acquires its natural eye color, inherent in it by genetics.
Melanin is present in both the anterior and posterior layers of the iris. However, the pigment content in its frontal part determines the decisive importance.
People with blue eyes do not have melanin, so in fact their iris color is just an “illusion”, which acquires a shade due to the property of Rayleigh light scattering.
Carriers dark eyes have great content melanin, and people with green eyes have less pigment than brown-eyed people, but more than blue-eyed people.
At very large cluster melanin in the iris, it acquires a very dark shade, creating the effect of black color.
Eye color is determined by eight genes. The most responsible is the OCA2 gene, located on chromosome 15. It produces a protein called P protein, which helps create and process melanin.
Every person has two copies of each gene in their DNA: one copy inherited from mom and one from dad. The dominance of one copy of a gene over another means that the dominant copy determines the color of the iris, and the properties of the other gene are suppressed.
The combined function of a number of other genes can increase melanin in the eyes to more high level than either parent, which explains how parents with light-colored irises sometimes give birth to dark-eyed children.
Interesting! Recent studies have shown that blue eye color only occurred in the last 6,000 to 10,000 years and is a genetic mutation.
So, what types of eyes are there? Which eye color is the rarest and which is the most common? And also, what is the name of the condition when the color of the iris of one eye is different from the other? Let's look at the different colors of the iris of the human eye.
Chestnut is the most common eye color in the world. Most of the world's population are its carriers. Color is determined high content pigment and the dominant gene in the pair.
In humans, right-handedness dominates over left-handedness, and brown eye color is the most common color among the population.
A lot of brown-eyed people live in African and Asian countries.
They are considered a mixed eye color - only about 5-8% of the world's population are carriers of it. The color has high concentration pigments are closer to the center and less at the borders, which creates the effect of a multi-colored iris: from yellow-green to brown.
Blue eyes are caused by mutation and are therefore much less common throughout the world. This color is determined by the complete absence of melanin.
The blue color of the eyes is due to Rayleigh scattering as it reflects light from the iris.
Interesting! Scientists recently discovered a fact: people who have blue eyes descended from the same ancestor!
Due to the mixed racial groups, blue eyes having recessive genes, are becoming less and less common. The largest number of speakers is concentrated among nationalities located near the Baltic Sea in northern Europe. According to various estimates, about 8% of the world's population are their carriers.
This is the most rare color eyes in the world, only about 2% of the world's population have them. Today, about 7 billion people live on the planet, which means that only 140 million of them are green.
They are often confused with swamps, but it is completely different - more distinct and concentrated. Green eye color is due to a small amount of pigmentation in the eye. The combination of golden with natural blue light scattering results in this color.
Most common in European countries, as well as in Western Asia.
Attention! Those with green eyes are more susceptible to harmful effects rays of the sun. This is due to the previously mentioned pigment melanin. Simply put, people with this iris color more likely development certain types cancers such as intraocular melanoma.
People with light eyes should definitely wear Sunglasses outdoors during periods of strong sun exposure.
Gray eye color can be mistakenly considered a shade of blue. "Silver" eyes are the result of low melanin content and reflect gray-silver appearance. They tend to have brownish-golden spots and can vary from gray to blue and green due to environmental conditions and emotional state.
Light and dark gray color is typical for natives of Eastern European countries, and it can also be classified as rare.
A shade of yellow-copper tone that is formed as a result of yellow pigment. Amber eye color is also very rare.
They are most common in Asian countries and southern America. The color of this eye color can vary from golden yellow to a more copper tone.
This effect can be found with a mutation when melanin is completely absent (for example, in albinos). As a result, blood vessels are strongly emphasized.
The red color you see in this image is a reflection of the flash at the back of the iris, which is filled with blood vessels.
This unusual coloration of the iris is caused by a genetic mutation. This deviation is called “born in Alexandria.” There are many legends associated with this color, the confirmation of which no one has ever found.
The first case was recorded in the 1300s. The deviation does not affect the quality of vision.
You must have heard about people who have eyes of different colors?
A condition in which one eye acquires one color, and the other has another, is commonly called heterochromia.
It is believed to be caused by mutations in the genes responsible for melanin distribution, which are often altered due to chromosomal homogeneity. The picture shows a woman with different eye colors: one is dark brown, the other is blue-gray.
It is believed that the eyes do not lie. One way to “read the truth” is to study the color of the human eye.
So, what does eye color mean and how does it affect temperament?
1. Dark brown – what does this eye color say about its owners?
Owners of such eyes can act tough and cold-blooded, while at heart they are quite sensitive natures. They combine confidence, simplicity and modesty.
People with brown eyes are considered wonderful lovers. Carriers brown eyes dark shades are known for their leadership abilities and are less likely to succumb to various addictions. They have enormous mental power.
2. Green eye color and its secret.
The rarest eye color in the world is possessed by persistent and stubborn people who always defend their point of view. They adapt well to any conditions. This eye color in a person causes universal admiration, so such people are accustomed to increased attention to yourself. They are distinguished by their honesty and secretive nature.
3. Blue color of the iris - what does it mean?
Blue iris color is the second most common color in the world. It is believed that people with blue eyes are immune to pain and have high pain threshold. They also demonstrate excellent endurance and developed analytical thinking. Patient people have this eye color.
4. Black color of the iris - the meaning of this eye color?
People with black eyes are very reliable. They are good secret keepers - you can trust them. They are very responsible and friendly. They are able to withstand pressure and not change under the pressure of time and circumstances, and are also not susceptible to emotional shocks. People with black eyes are considered very good advisors.
5. Light eyes.
People with light eyes are very sensitive to the pain of others, while also being even more vulnerable to their own. They will always come to the rescue and are good comforters. People with lighter shades of eyes (light gray, light blue or light green) are funny, helpful, and friendly. They can easily cheer up and are great optimists.
6. Swamp color and what it means
Hazel is an unusual eye shade, but if you own it, you've hit the jackpot. All in one: brown, yellow, green, each of which makes its contribution. Such people are strong, sensitive and hidden, have enormous physical strength and endurance.
7. Gray eye color and what it indicates.
People with gray eyes sometimes suffer from intense internal conflict, they often find it difficult to make decisions, and they are prone to constant skepticism.
Is it possible to accurately determine a person's character by eye color? Of course, no one will give you a 100% guarantee. Each person is a unique individual with his own set of characteristics, abilities and inclinations, regardless of the color of our eyes. But to trace some patterns of similarity in the behavior of people with general color you can, and it’s hard to ignore.
Can eye color change? Many people are curious whether the iris can acquire a different color and why eye color changes.
Reasons why eyes change color:
There are diseases causing change iris color. For example, Fuch's heterochromic iridocyclitis, Horner's syndrome, or pigmentary glaucoma often cause changes in eye color.
Attention! In situations where your eye color changes suddenly for no apparent reason and your pupils remain dilated for long period time, consult a doctor immediately. This may have serious reasons, and consulting an ophthalmologist will not hurt you.
Also some medications from glaucoma can cause changes in the color of the iris. Eye drops prescribed for glaucoma can affect the shade of the iris, changing it to a darker side.
In 10-15% of Caucasians, eye color changes with age. The brown color of the iris may lighten or, on the contrary, darken over the years.
Is it possible to change your eye color yourself? When someone wants to improve their vision, they can try contact lenses or use the services eye surgery. But what if they want to change the color of their iris? How to change eye color?
If for some reason you are unhappy with your eye color, you can use colored contact lenses.
Attention! Don't buy them online or borrow them from a friend - you risk getting an eye infection. The best option There will be an ophthalmologist consultation.
If you want to solve the issue more radically and change the color completely, then today there are technologies that can offer those who want one more service - this is an operation to change eye color.
This operation involves inserting a colored implant into the eye. The procedure is painless and does not require anesthesia. In just a few minutes the patient acquires the desired color. The implant can subsequently be removed.
Another method of surgery is laser burning of melanin to form light eyes. This method is not yet widely practiced. The procedure takes no more than 30 seconds, and within a few weeks you will have a completely different eye color. It should be noted that this is forever and it will not be possible to return the previous color.
The eyes are definitely the window to the soul, and if you know anything about eyes or windows, you know they come in different shades and colors!
Most often, you see brown, blue or hazel eyes when you look at people around you, but some people have very rare eye colors. What are the rarest eye colors and how are they obtained?
Only 2% of the world's population has green eyes! Talk about rare! The next time you see someone with this color, let them know this fact.
This list rare flowers The eyes are in no particular order, and if your eye color is one of those listed, consider yourself a very rare person.
Have you ever seen someone with eyes that seem black as night? Even though they appear black, they are actually just very, very dark brown. This is caused by an abundance of melanin. You can only tell the difference between a pupil and an iris when looking at a person in bright light!
Two main conditions cause the eye color to appear red or pinkish: albinism and blood leaking into the iris. Although albinos typically have very light blue eyes due to a lack of pigment, some forms of albinism can cause the eye color to appear red or pink.
This beautiful golden eye color is often confused with brown. The difference is that brown eyes have brown and green shades, while amber eyes have a uniform color. With a little melanin and a lot of carotenoid, the eyes of this shade almost glow! Several different animals have this eye color, but it is truly rare in humans.
Very little melanin, but too much carotenoid. Only two percent of the world's population have green eyes. This is definitely a very rare color!
Oh, what purple-blue! This color is most often found in people with albinism. They say it is impossible to have purple eyes without albinism. Mix the lack of pigment with the light reflecting off blood vessels in the eyes and you get that beautiful purple color!
This is not a set of colors, but quite rare disease eye:
This is a rather unusual type of eye. And some people wear contact lenses to make their eye color more uniform. And I think that this eye color is beautiful, and such a rarity should be appreciated by others!
Many people argue that these are purely genetic factors. For the most part this is true. However, there are also genes that determine a person's eye color.
We now know what determines eye color:
When you see someone with slightly blue eyes, it means there is a lack of melanin or brown pigmentation.
It is believed that the human race previously only had brown eyes and due to genetic mutations, other options appeared. Perhaps this is why brown is the most common (but no less beautiful)!
So many people who have perfect vision choose to wear contacts just to have a rare eye color, so if you have a rare color, consider yourself lucky!

It is worth mentioning that the seven billion inhabitants of the planet have several hundred shades of the iris. But, as we know, there are not many basic colors.
Eyes of a beautiful dark brown tone are the adornment of most people in the world. It is generally accepted that all people had dark color eyes, light shades appeared much later under the influence different stages evolution.
There are especially many people with brown eyes in the east. And in general, this shade is typical for residents of the south and east. Brown eyes, unlike light ones, have a huge number of shades; one of the rarest and most unusual is yellow, called amber. The color is very beautiful, and people who have it have a very piercing gaze. There are very few such people; they arouse excessive interest and are often unreasonably endowed with supernatural abilities.
Celestial eye color is found in people much less frequently than what has already been described. As a rule, it is typical for residents of the north. Perhaps that is why the shade is very cold. The blue-eyed inhabitants of the planet, for the most part, have light, thin skin and blond hair.
Blue color is also rich in shades. Among such eyes, there are both light and dark. An example of this could be close-ups photos of models, however, most often, to obtain the desired effect, they use special ones.
Gray eyes are the least abundant, but they are not considered the rarest. Typically this color is dominant among northeastern peoples.
Gray eyes have one interesting feature. They, depending on the environment and the mood of the owner, are able to change shade. It looks very beautiful.
In the body, a special pigment is responsible for eye color. The amount of one or another pigment determines the color. Blue color is an exception, as it is formed by the refraction of light rays. Along with yellow, this color is no less rare. It is worth mentioning the color indigo - it is a special blue. This blue is deeper, and occasionally there are cases with a bias towards purple.
Green eyes are also quite rare when it comes to the rich color of young grass. Much more common is dark green, marsh. This eye color is characteristic of Westerners, although today this is no longer an indicator. Light green eyes have always been considered a sign of exclusivity. For example, among the ancient Slavs, such eyes were sufficient reason to classify a person as “ evil spirits" However, there is nothing mystical, except for unusual beauty, in the green shade of the eyes. By the way, they are also quite rare, especially in European countries.
The seven billion inhabitants of the planet have several hundred shades of the iris.
The classification of eye shade is determined using certain color scales. The Bunak scale, for example, gives the “title” of the rarest yellow color. And it divides all types of shades into several types, subdivided into dark, light, and mixed types. All types, according to this scale, have their own set of characteristics. It is worth noting that according to the Bunak scale, blue eye color is also considered rare. Indeed, blue and yellow shades of the iris are extremely rare. Moreover, it is impossible to determine with one hundred percent accuracy the territory where the number of carriers of such colors is greatest.
There is another color scale - Martin Schultz, it is somewhat more complicated and includes about 16 shades. By the way, it contains another very rare color – black. Actually, black eye color is not absolutely black, it is a dark shade of brown that can be mistaken for black.
Among the variety of eye shades of the multi-billion army of inhabitants of the planet, there are also complete anomalies. For example, the eye color of albino people in the case of complete absence pigment, when even the pupils have White color. There is also another pathology - different eye colors. By the way, this is not so rare, although such an anomaly is now being corrected. Such “miracles” do not particularly affect vision, being considered a purely aesthetic defect.
