What determines the color of a person's eyes? What do different eye colors mean in people? One eye is green, the other is brown.

My friend got a kitten, fluffy and very funny. But his eyes are different colors - one is blue, the other is green. Please tell me, does this not affect his health, does he see well? And is this normal? Daria

Hello, Daria! And, you know, your friend is lucky! It is believed that having such a miracle as a cat with different eye colors is good luck.

Let's take a closer look at this interesting phenomenon. The difference in the color of the iris of the eyes is called disagreement or heterochromia (from the Greek words “heteros” - different, different and “chroma” - color) - different colors of the iris of the right and left eyes or unequal coloring of different parts of the iris of one eye. In other words, the term heterochromia refers to both the presence of an area (segment) of a different color in one eye, and the case when both eyes have a completely different color.

Heterochromia occurs in some animal species, and even in humans, but is most common in cats. The most common is complete heterochromia, when a cat has one eye that is entirely orange, golden, yellow or green, and the other is blue. Cases of partial heterochromia, when only part of the eye is colored a different color, are much less common.

Cause of heterochromia lies in different concentrations and uneven distribution of melanin - a natural coloring pigment - in the iris of the eyes. An eye affected by heterochromia may be hyperpigmented (excess melanin) or hypopigmented (lack of melanin).

Now attention! In albinos, melanins may have a reduced concentration and even be completely absent (!). This explains the fact that blue eye color is more often observed in cats of white color or in cats with a large percentage of white in color . Therefore, odd-eyedness is especially common among cats of the Angora or Turkish Van breeds (originally white cats).

And to make it completely clear (or completely unclear :-)) A littlegenetAndki:

The peculiarity of the white color is that its gene is one of the strongest in domestic cats in its effect not only on blocking coat pigmentation, but also on the development of the rudiments of the nervous system. Under its influence, changes in the organs of vision and hearing may occur.

Due to the white color gene, there may be no pigment in the iris of the eye, which visually appears blue. It can be bilateral (both eyes) or unilateral (only one eye) blue eyes. It has been found that in completely white cats with eyes of different colors, deafness usually occurs in the ear located on the side of the blue eye.

The heterogeneity of all-white cats is formed under the influence of the dominant and dangerous gene W - White, which in homozygous form (when only this gene is present) is considered lethal, that is, leading to the death of kittens even inside the womb. Therefore, all pure white cats can only be heterozygous, that is, in a pair with the white color gene, “non-white” is necessarily attached, due to which colored kittens are also born in litters from white parents.

Divergence of eyes does not affect vision(!) , therefore heterochromia is not considered a disease.

Agree that cats with different eye colors look very mysterious, and certainly, in modern terms, cool!

Eye color is of great importance in a girl's life, even if we don't think about it. Very often, clothes and accessories are chosen directly to match the color of the eyes, not to mention the fact that thanks to existing stereotypes, we, to some extent, form our initial opinion about a person taking into account the color of his eyes.

Therefore, when special lenses appeared that changed eye color, many girls rushed to purchase them in order to create images with different eye colors. And besides lenses, Photoshop helps us, with its help you can achieve any color, but unfortunately this is displayed only on the monitor screen and photographs.

What determines the real color of a person's eyes? Why do some people have blue eyes, others green, and some even boast purple ones?

The color of a person’s eyes, or rather the color of the iris, depends on two factors:

1. Density of iris fibers.
2. Distribution of melanin pigment in the layers of the iris.

Melanin is a pigment that determines the color of human skin and hair. The more melanin, the darker the skin and hair. In the iris of the eye, melanin ranges from yellow to brown and black. In this case, the back layer of the iris is always black, with the exception of albinos.

Yellow, brown, black, where then do the blue and green eyes come from? Let's look into this phenomenon...

Blue eyes
The blue color is due to the low fiber density of the outer layer of the iris and the low melanin content. In this case, low-frequency light is absorbed by the back layer, and high-frequency light is reflected from it, so the eyes turn out blue. The lower the density of the fibers of the outer layer, the richer the blue color of the eyes.

Blue eyes
Blue color occurs when the fibers of the outer layer of the iris are denser than in the case of blue eyes and have a whitish or grayish color. The higher the fiber density, the lighter the color.

Blue and blue eyes are most common among the population of northern Europe. For example, in Estonia up to 99% of the population had this eye color, and in Germany 75%. Only given modern realities, this situation will not last long, because more and more people from Asian and African countries are trying to move to Europe.

Blue eye color in babies
There is an opinion that all children are born blue-eyed, and then the color changes. This is a wrong opinion. In fact, many babies are actually born light-eyed, and subsequently, as melanin is actively produced, their eyes become darker and the final eye color is established by two to three years.

Grey colour it turns out similar to blue, only in this case the density of the fibers of the outer layer is even higher and their shade is closer to gray. If the fiber density is not so high, then the eye color will be gray-blue. In addition, the presence of melanin or other substances gives a small yellow or brownish impurity.

Green eyes
This eye color is most often attributed to witches and sorceresses, and therefore green-eyed girls are sometimes treated with suspicion. Only green eyes were obtained not due to witchcraft, but due to a small amount of melanin.

In green-eyed girls, yellow or light brown pigment is distributed in the outer layer of the iris. And as a result of scattering by blue or cyan, green is obtained. The color of the iris is usually uneven; there are a large number of different shades of green.

Pure green eye color is extremely rare; no more than two percent of people can boast of green eyes. They can be found in people in Northern and Central Europe, and sometimes in Southern Europe. Women have green eyes much more often than men, which played a certain role in attributing this eye color to witches.

Amber
Amber eyes have a monotonous light brown color, sometimes with a yellowish-green or reddish tint. Their color can also be close to marsh or golden, which is due to the presence of lipofuscin pigment.

Swamp eye color (aka hazel or beer) is a mixed color. Depending on the lighting, it may appear golden, brown-green, brown, light brown with a yellow-green tint. In the outer layer of the iris, the melanin content is quite moderate, so the marsh color is the result of a combination of brown and blue or light blue. Yellow pigments may also be present. Unlike amber eye color, in this case the color is not monotonous, but rather heterogeneous.

Brown eyes
Brown eye color results from the fact that the outer layer of the iris contains a lot of melanin, so it absorbs both high-frequency and low-frequency light, and the reflected light adds up to brown. The more melanin, the darker and richer the eye color.

Brown eye color is the most common in the world. But in our life, this - which is a lot - is valued less, so brown-eyed girls sometimes envy those to whom nature has given green or blue eyes. Just don’t rush to be offended by nature, brown eyes are one of the most adapted to the sun!

Black eyes
Black eye color is essentially dark brown, but the concentration of melanin in the iris is so high that the light falling on it is almost completely absorbed.

Red eyes
Yes, there are such eyes, and not only in the movies, but also in reality! Red or pinkish eye color is found only in albinos. This color is associated with the absence of melanin in the iris, so the color is formed based on the blood circulating in the vessels of the iris. In some rare cases, the red color of the blood mixes with the blue to produce a slight purple tint.

Purple eyes!
The most unusual and rare eye color is deep purple. This is extremely rare, perhaps only a few people on earth have a similar eye color, so this phenomenon has been little studied, and there are different versions and myths about this that go back centuries. But most likely, violet eyes do not give their owner any superpowers.

This phenomenon is called heterochromia, which translated from Greek means “different color”. The reason for this feature is the different amount of melanin in the irises of the eye. There is complete heterochromia - when one eye is one color, the other - another, and partial - when parts of the iris of one eye are different colors.

Can eye color change throughout life?
Within one color group, color can change depending on lighting, clothing, makeup, even mood. In general, with age, most people's eyes lighten, losing their original bright color.

I wonder how a person with such a difference from others feels? Surely, people with different eyes feel a little constrained, realizing that they are different from the rest, even if only slightly. And we, ordinary people, look at them and somewhere in the depths of our souls, or maybe we quite clearly admire it. A person’s desire to stand out is quite normal, therefore, the desire to be in the place of those who are “different” from him is justified. We conclude that you should not be ashamed of your distinctive features, especially since many, as mentioned, try to recreate something similar, resorting to certain means.

Although, is this so, do people with different eyes really not like to be like that? There is a lot of material that reveals human sides from different sides - meleosophy, which studies moles on the human body, philosophy, psychology, physiology, biology, palmistry and many other areas that are so different from each other. An attempt to characterize a person by eye color was not an exception. Tons of articles that describe people with brown, green, blue eyes. What can you say about a person whose eye color is not the same? Let's figure out what different eye colors mean in people!

Congenital and acquired “diversity of eyes”

In science, the phenomenon of people with different colored eyes was considered from a genetic point of view and is called heterochromia - a different color of the iris of one eye from the other. It is the result of a relative excess or deficiency of melanin. But there is also acquired “diversity of eyes,” for example, as a result of injury, in people with glaucoma or with tumors.

Psychological portrait of people with different eye colors

Egocentrism

Such people are characterized as fearless, unpredictable and extraordinary individuals. They are incredibly generous. Against the background of these significant positive qualities, there is an obvious negative - egocentrism in a pronounced form. “How is it possible that they didn’t pay attention to me?!” It is very difficult to get along with egoists; they demand an excessive amount of attention. But here’s a paradox: people who have different colors of the iris love loneliness. Strange, isn't it? Although, why be surprised? Against this background, they have a narrow circle of friends who are valued and loved. Well, how can you not appreciate those who tolerate and accept your selfishness?

Striving for ideal

Women with different eyes strive for the ideal. They may be overweight in physique, so they often resort to diets. However, this does not prevent them from enjoying their appearance, simply “there is no limit to perfection.” Ladies are subtle by nature, love poetry, music, dancing, and are very cheerful.

Moderate lifestyle

The life schedule is not tight, if any bright events happen, it is quite rare. True, this does not particularly upset them; on the contrary, it makes them appreciate what they have and will be imprinted in their memory for a long time. They are quite capable of organizing a holiday for themselves and do so thanks to their good organizational skills and imagination.

Patience and endurance

Positive qualities include good patience and endurance. You may not even know about their problems - they only spread their worries or dissatisfaction when the boiling point has been reached. And then only those closest to you will know. They do not strive to jump over their heads; they are content with their current position.

Ideal wives

In relationships, at first glance, they are flighty, but if the “different eyes” left you, it was only because for her you are not the one and only, and there can be a lot of them. When she finds the one, it will be “love until the grave,” with radical changes in behavior. It would seem that in a wild girl you will see an excellent housewife who will always maintain comfort in the house and, if you wish, will share useful wisdom. Don't let the advice fall on deaf ears. The husbands of such ladies will be envied, because all selfishness will turn in a completely different direction - she will “live for her man.”

So, in addition to the fact that such a girl will be an excellent housewife, a caring wife, she, of course, will not forget to take care of her appearance. For any man, it seems to me, this is the ideal wife. True, there are qualities that a husband can accept, or maybe categorically not. “Odd-eyed” women are addicted to alcohol, but, due to their intelligence, they avoid it. But once you try smoking, you may never be able to quit.

Stubbornness and straightforwardness

People with different-colored eyes are characterized by stubbornness and capriciousness, do not forget about this. In a dispute or quarrel, they will stand their ground to the end. They can be rude, but only in extreme cases, when the opponent cannot understand otherwise. They try not to show these qualities to others.

Try to choose your words when communicating with them. They forgive easily, but the offense will be remembered for a long time. They do not know how to hint and are not able to understand hints themselves, which indicates their straightforwardness. “Better the bitter truth than a sweet lie” is the motto with which they go through life.

We hope it will now be easier for you to understand such unusual and controversial people.

Incredible facts

Brown-eyed people are more trustworthy than blue-eyed people, scientists have found.

However, as researchers from Charles University in Prague, it is not the eye color itself that inspires confidence. When a group of volunteers were shown photographs of the same men whose eye color had been artificially changed in different photographs, they were considered more reliable.

This suggests that It’s not the eye color itself that inspires trust, but the facial features inherent in brown-eyed people.

For example, brown-eyed men tend to have a rounder face with a wide chin, a wider mouth with raised corners, larger eyes and closer eyebrows. All these qualities indicate masculinity and therefore inspire confidence.

In contrast, blue-eyed representatives of the stronger sex more often have facial features that are perceived as a sign of cunning and changeability. These are, as a rule, small eyes and a narrow mouth with drooping corners.

Women with brown eyes are also considered more trustworthy than those with blue eyes, but the difference is not as pronounced as for men.

One of the first features that attracts us to a person is their eyes, and especially their eye color. Did you know what eye color is considered the rarest, or why eyes can be red? Here are some interesting facts about human eye color.

Brown eye color is the most common eye color

Brown eye color is the most common eye color in the world, with the exception of the Baltic countries. It results from the presence of large amounts of melanin in the iris, which absorbs a lot of light. People with very high concentrations of melanin may appear as if their eyes are black.

Blue eye color is a genetic mutation

All people with blue eyes have one common ancestor. Scientists have traced the genetic mutation that led to the appearance of blue eyes and found that it appeared 6000 - 10000 years ago. Before that time there were no blue-eyed people.

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

Yellow eye color – wolf eyes

Yellow or amber eyes have a golden, tan or copper tint and are the result of the presence of lipochrome pigment, which is also found in green eyes. Yellow eye color is also called “wolf eyes”, as this is a rare eye color common among animals such as wolves, domestic cats, owls, eagles, pigeons and fish.

Green is the rarest eye color

Only 1-2 percent of people in the world have green eyes. Pure green eye color (which should not be confused with marsh color) is a very rare eye color, as it is often eradicated in the family by the dominant brown eye gene. In Iceland and Holland, green eyes are most common in women.

One person can have eyes of different colors

Heterochromia is a phenomenon in which one person can have different eye colors. It is caused by too much or too little melanin and is the result of a genetic mutation, disease or injury.

With complete heterochromia, a person has two different colors of the iris, for example, one eye is brown, the other is blue. With partial heterochromia, the color of the iris is divided into two parts of different colors.

Red eye color is common found in albinos. Since they have almost no melanin, their irises are transparent but appear red due to the blood vessels.

Eye color can change throughout a person's life. African-Americans, Hispanics and Asians are typically born with dark eyes that rarely change. Most Caucasian children have light colored eyes at birth: blue or blue. But over time, as the child develops, the cells in the iris of the eye begin to produce more melanin pigment. Usually, A child's eye color changes by one year of age, but can be established later by the age of 3, and less often by 10-12 years.

In rare cases, changes in eye color throughout life may also indicate certain diseases, such as Horner's syndrome, some forms of glaucoma and others.

The formation of eye color is a complex process that is determined genetically. There are many combinations of genes that we get from both parents that determine the eye color you will have. Here is the most simplified diagram that will help you find out the eye color of your unborn child.
