This is the main component of the eye. It consists of several shells. The upper layer of the eye is the transparent cornea, followed by the choroid and iris. It is in the choroid that there are pigment cells and blood vessels. The iris, which is located at the front of the eye, is responsible for its color. In one of the deep layers of the iris there are chromatophores, which contain the coloring pigment melanin, which shines through the cornea.
The less melanin, the lighter the eye and vice versa. Eye color is often associated with a person’s place of residence. Nations with live far away, with brown - live in temperate climate zones, people with black eyes live very close to the equator, in hot countries. Residents of the Far North, although they live on the continent, have Brown color eyes, so their eyes are protected from the blinding reflection of the snow. The lighter the eye, the worse it is protected from sunlight.
Conducted genetic research proved that the gene for brown eyes is the strongest and defeats green and blue eyes.
How did blue-eyed people appear?
Scientists at the University of Copenhagen conducted genetic studies of blue-eyed people. To conduct the experiment, Professor Eisberg invited more than 700 respondents from blue eyes completely different nationalities. During the experiment, it was found that 99.5% of the experimental subjects had the same mutation of the gene that is responsible for the color of the iris.
Eisberg believes that everyone has an ancestor modern people one with blue eyes. He managed to find out that the first blue-eyed man appeared about 6-10 thousand years ago during the migration of the inhabitants of the Middle East to Europe.
According to scientists, the mutated HERC2 gene appeared in the northwestern part of the Black Sea region.
From time immemorial, blue eye color has been considered something mysterious and bewitching. There are not so many people with eyes of this color - this can be explained by the fact that the gene responsible for blue color is recessive, and for brown - so it turns out that a child can be born with blue eyes 3 times less often than with brown eyes. Scientists continue research in this area, but we can already say that blue-eyed people are much more vulnerable to sun rays than people with dark color eye.
The compatibility of people can be checked not only by horoscope, by blood type, but also by eye color.
Brown-eyed and green-eyed
Initially, you will most likely behave like opponents: fire and water are enemies. But if you become friends, your union has a promising future. It will be very useful for both sides. Fire boils water, which means that the brown-eyed will be able to take action, struggle, and creativity with the green-eyed. Water extinguishes fire, i.e. a green-eyed person can protect a brown-eyed person from rash actions.
It is important to listen to mutual advice. Since water is the leader in your relationship, fire should not forget about this even for a minute.
If the brown-eyed one even once imagines that he is the main one in your union, the tandem will most likely fall apart. At the same time, water will survive the conflict almost painlessly, but fire will suffer and suffer.
Brown-eyed and blue-eyed
You can say the following about your relationship: “together is crowded, but apart is boring.” You are very interested in each other. Even sometimes it’s not comfortable, but it’s interesting. Because your communication is constant bickering, arguing, picking, exchanging all sorts of barbs. Such a relationship turns on and excites both of you. Moreover, it is usually the brown-eyed one who starts teasing and provoking. After all, in your union, fire is the leader.
However, the blue-eyed man does not pretend to be a leader. If his communication with the brown-eyed one becomes bad, he will simply go to someone else. Treason in the air does not cause moral feelings. Therefore, your union will be long, provided that in constant polemics, the brown-eyed one will still spare the blue-eyed one, and will not cross the dangerous line.
Brown-eyed and gray-eyed
You are probably keeping your distance in relationships. You will never reveal your deepest secrets to each other, and you will never become truly close friends. But you are still strong, at least in that you can provide each other with an irreplaceable mutual service. You are mutually useful in your work. Fire, when starting to solve a problem or business, can rely on the wisdom, strength, and confidence of the earth. And earth, in communication with fire, can borrow its dynamism and courage. Therefore, your advice to each other is extremely effective. So it is important to strive to become closer; respect for each other is something that can preserve your union for many years. After all, your relationship is a relationship of equals - there is no leader in this tandem, and there should not be one.
Brown-eyed and brown-eyed
You understand each other well, but sometimes it is difficult to get along. Often you pull the blanket over each other. You constantly envy the success of others. You often weave mutual intrigues. But you know for sure: if trouble happens to one of you, the other will definitely come to the rescue. And this assistance will be comprehensive and selfless. Your relationship will be long-lasting and very fruitful if you have a common enemy (a competing company, boss, harmful neighbor, etc.), in the fight against which you need to join forces. If there is no worthy opponent, your relationship will be characterized by petty dirty tricks against each other. But you better not become enemies. In this case, both of you will die; there will be no winner in this war.
Green-eyed and blue-eyed
Your relationship is not a friendship right now. And they never will be. You are too different to just be friends. Your relationship is one of mutual activation. Having become the wind, the air can stir up the water, foam it, cause a storm, excitement. This means that a blue-eyed person is capable of inspiring a green-eyed person to decisive activity, to search for new ways solving many problems, moving towards the most distant horizons. And water will achieve a lot in life if it responds to the call of the wind. But the wind also gains a lot in such communication: weight in society, authority, increased self-esteem.
However, your coalition should not be permanent, as the waves dampen the wind.
Green-eyed – gray-eyed
This is an extremely fruitful union. True, under one condition: if the leader in it is the gray-eyed one. He must not allow the water to overflow its banks. If water accepts the guiding principle of the earth, it will achieve many things in life, in creativity, career, love. After all, the gray-eyed one is ready to provide any support to the green-eyed one: with money, and advice, and physical strength. In return, water can provide comfort to the earth, becoming a real comforter and, if necessary, a healer. If the water turns out to be obstinate and rebels against the supremacy of the earth, it will cause a real flood, and it will be bad for both. Having gained freedom, the green-eyed one will not be able to manage it and will get stuck in his petty problems. And the gray-eyed one will lose his mental balance and dry up his soul. It is important to remember this and preserve your relationship.
Green-eyed and green-eyed
First of all, it is a mutually supportive relationship. You act in relation to each other as psychotherapists. If one of you feels bad, he can always cry into the other’s vest. There are no taboo topics for conversation when you are together; at these moments you can be frank and sincere to the end. Because you will always find understanding without judgment. But it is harmful for you to stay together for too long.
This will lead to dulling of the senses: water becomes musty when standing still.
Jealousy can also ruin your relationship. If you seriously start to be jealous of each other for someone else, this could end in a war in which there will be no restrictions on the use of any types of weapons. Fraud, slander, and physical violence will be used. Try to be above jealousy, do not try to take revenge on each other, and then your friendship will be endless.
Blue-eyed and gray-eyed
You are quite different people. You have very little in common. But if you are together, then it is likely that your union is being held together by simple curiosity. And mainly curiosity on the part of the gray-eyed one. After all, it is difficult for the earth to understand and accept all the playfulness of the air. And at the same time, she is infinitely envious, and she dreams of at least sometimes being as passionate, carefree, and romantic. The gray-eyed one, while internally condemning you in your relationship, still admires the blue-eyed one. And blue-eyed allows you to do this. After all, in this pair he occupies a leading place. Therefore, your relationship depends on how long the air will be pleased with the attention of the earth. And also from that moment, will the earth have enough wisdom not to teach or even criticize the air. If the gray-eyed one tries to become a leader and begins to impose on the blue-eyed one own view at the world, and the latter will simply turn around and leave, not in any way saddened by the termination of the existing relationship.
Blue-eyed and blue-eyed
It’s very easy for you to be with each other, as only air can be easy. When you exchange mutual visits, you bring a carefree and cheerful holiday atmosphere to your friend’s house. You easily heal each other from grief, sadness and longing. But it’s not just shared leisure time that can unite you. Your relationship will become very close if true love arises or a common high goal appears. Or in the case when you are united by some adventurous adventure. But painstaking joint work is unlikely to bring you pleasure. If you one day decide to break up, it is better to do it painlessly, you will not take revenge or be offended. You'll just remain good friends. Therefore, in any situation, the future of your relationship should be optimistic.
Gray-eyed and grey-eyed
Your relationship is a union of two oxen, tightly harnessed to the same plow. They lack grace and romance. They contain only profitability and usefulness. And also great mutual respect. Together you can truly move mountains. But if one of you begins to be lazy and shirk your responsibilities, conflict is inevitable. But, even if suddenly the conflict does not lead to an immediate break in your relationship. The separation will be painful and long. And when you break up, both of you will regret what happened. Take care of each other.

From a school biology course, we know how the color of a child’s eyes is genetically determined, we know that brown color dominates blue and it happens that a person’s eyes different color. We will tell you facts you didn't know. For example, at what age does eye color develop and why does our iris have one color or another?
Fact 1: all people are born with bright eyes
Please note that all newborn babies have eyes gray-blue color. Ophthalmologists explain this very simply - babies have no pigment in the iris. There are exceptions only in the countries of East, Southeast and South Asia. There, children's irises are already saturated with pigment.
Fact 2: final color we gain eyes in adolescence
The color of the iris changes and forms by 3-6 months of a child’s life, when melanocytes accumulate in the iris. The final eye color in humans is established by the age of 10-12 years.
Fact 3: brown eyes are blue eyes
Brown is the most common eye color on the planet. But ophthalmologists say that brown eyes are actually blue under the brown pigment. This is a consequence of a genetic mutation. The outer layer of the iris contains a large number of melanin, resulting in the absorption of both high-frequency and low-frequency light. Reflected light results in a brown (brown) color.
There is a laser procedure that can remove pigment and make your eyes blue. It is impossible to return the previous color after the procedure.
Fact 4: in ancient times everyone was brown-eyed
Researchers have found that 10 thousand years ago, all inhabitants of the planet had brown eyes. Later, a genetic mutation appeared in the HERC2 gene, whose carriers decreased the production of melanin in the iris. This led to the appearance of the color blue for the first time. This fact was established by a group of scientists at the University of Copenhagen led by Associate Professor Hans Eiberg in 2008.
Fact 5: a little about heterochromia
This is what is called the different color of the iris of the right and left eyes or the unequal color of different parts of the iris of one eye. This feature is explained by the fact of excess or deficiency of melanin due to diseases, injuries, genetic mutations. With absolute heterochromia, a person has two different colors of the iris. One eye may be blue, the other - brown. There are 1% of people on the planet with such an unusual deviation.
Fact 6: green is the most rare color eye
1.6% of people on the planet have green eyes; it is the rarest, as it is eradicated in the family by the dominant brown gene. Green color is formed like this. The outer layer of the iris contains an unusual light brown or yellow pigment called lipofuscin. In combination with the blue or cyan color resulting from scattering in the stroma, green is obtained. Purely green color eye is extremely rare: the color of the iris is usually uneven, and this leads to the appearance of numerous shades. Most often, green eye color occurs in those whose genotype is dominated by the gene responsible for red hair color. Swiss and Israeli scientists came to these conclusions. These findings are indirectly confirmed by the high prevalence of green eyes among red-haired people. The results of the study were published in the “Genetic Nature” section of the Nature.Com portal.
Fact 7: a little about other colors of the iris
Black color the eye is similar in structure to brown. But the concentration of melanin in the iris is so high that the light falling on it is virtually completely absorbed. Black eye color is the most common among representatives Mongoloid race in East, Southeast and South Asia. In these regions, the iris of newborn children is already saturated with melanin.
Blue color The eye is the result of light scattering in the stroma (the main part of the cornea). The lower the density of the stroma, the richer the blue color.
Blue eyes, unlike blue, is explained more high density stroma. The higher the fiber density, the lighter color. As we all remember, this beautiful color scheme was partly the reason for the formation of fascist ideology. After all, according to scientists, 75% of the indigenous inhabitants of Germany have blue eyes. No other country in the world has such a concentration of blue-eyed people.
Walnut color is a combination of brown (hazel), blue or light blue. And can acquire different shades depending on the lighting.
Grey colour the eye is similar to blue, while the density of the fibers of the outer layer is higher. If the density is not so high, the eye color will be gray-blue. Gray eye color is most common among residents of Northern and Eastern Europe, in certain regions of North-West Africa, as well as among residents of Pakistan, Iran and Afghanistan.
Yellow the eye is extremely rare. It is formed due to the content of lipofuscin pigment (lipochrome) in the vessels of the iris. But in most cases it is a fact of this color eye disease is due to the presence of kidney disease.
Fact 8: Albinos can have both red and purple eyes
The most unusual and interesting eye color, red, is usually found in albinos. Due to the lack of melanin, the irises of albinos are transparent and appear red due to blood vessels. In some cases, red, mixing with the blue color of the stroma, gives purple eye. However, such deviations occur in a very small percentage of people.

Eye color is inherited by one human gene, and from the moment of conception it is predetermined to have a certain shade. Scientists have calculated that there are 8 eye colors. And these are just the most common ones. But there are people on the planet who have the rarest eye color.
For example, Hollywood actress Kate Bosworth has eyes of different colors. The dark gray iris of her right eye contains age spot brown shade.
There are as many pairs of eyes in the world as there are people. No two personalities are identical, and no two pairs of eyes are identical. What is the magic of a look? Maybe it's the eye color?
From black to sky blue
Human eyes come in only eight shades. Some shades are more common, others very rare. The content of the melanin pigment in the iris determines what we call color. Once upon a time, about 10 thousand years ago, most people on Earth were brown-eyed. Genetics say that a mutation occurred, and people appeared with a lack of pigment. They gave birth to blue-eyed and green-eyed children. 
The following shades are known: black, brown, amber, olive, green, blue, gray, light blue. Sometimes the eyes change color, more often this happens in babies. Meet unique people with an indefinite shade. Aishwarya Rai, a film star from India, is known not so much for her stunning figure and smile, but for the mystery of her eyes, which can be green, blue, gray or brown in different moods and are recognized as the most beautiful eyes in the world.
What are the most eyes in the world?
Most often, brown-eyed children are born on the planet. This color predominates in all parts of the world. It is believed that their iris contains a lot of melanin. It protects your eyes from the blinding rays of the sun. Astrologers associate brown-eyed people with Venus and the Sun. Venus endowed these people with her tenderness, and the Sun with ardor and passion. 
According to sociological data, owners of such eyes inspire special trust in themselves. It is generally accepted that brown-eyed women are sexy and passionate. Whether this is true is unknown, but the fact is that the owner of dark brown eyes, Jennifer Lopez, is a symbol of precisely these qualities. The second most common color is blue. People originally from Northern Europe have such eyes. According to statistics, 99% of Estonians and 75% of Germans have blue eyes. Many children are born with blue eyes. Within a few months the color changes to gray or blue. Adult blue-eyed people are rare. Blue eyes are found both in Asia and among Ashkenazi Jews.
American researchers say that most talented people with high IQ blue eyes. Blue-eyed people are often strong, authoritative personalities; when communicating, trust in them arises intuitively. Cameron Diaz's light blue gaze, giving warmth and positivity, made her a Hollywood star. At the right moment he becomes hard and cold, and then again kind and warm.
The rarest eye shades
Black-eyed people are very rare. Of the Hollywood stars, only Audrey Hepburn had this color. She once said that the eyes are the gateway to the heart, where love lives. Her gaze always shone with kindness and love. 
Elizabeth Taylor had the rarest color. When she was born, her frightened parents took the girl to a doctor, who said that the child had a unique mutation. The future Cleopatra was born with double rows of eyelashes, and at six months the baby's eyes acquired a purple tint. Elizabeth drove men crazy with her gaze all her life, having been married 8 times.
The rarest color of the iris
The witch's eyes should be green. Only 2% of the world's population has green eyes. Moreover, most of them are female. There is no rational explanation for this phenomenon. Historians believe that human prejudices are to blame. Everyone has European peoples, including the Slavs, Saxons, Germans, and Franks, it was believed that green-eyed women had supernatural abilities. 
During the Middle Ages, the Inquisition was rampant in Europe. A denunciation was enough for a person to be sent to the stake. Most of the victims were women, who were declared witches for the most insignificant reasons. Is it worth saying that the green-eyed ones were burned first? So the population of people with the most beautiful color eye.
Today, 80% of green-eyed people live in Holland and Iceland. Astrologers believe that green-eyed women are the most gentle creatures, kind and devoted, but when it comes to protecting their family or loved one, they are merciless and cruel. Bioenergeticists who divide people into energy “vampires” and “donors” claim that green-eyed people are neither one nor the other, their energy is stable and neutral. Perhaps this is why they value stability and devotion in relationships so much, and do not forgive betrayal.
The most famous green-eyed beauty is Angelina Jolie. Her “cat-eye” broke a lot of hearts before it got to
