If nature has endowed a person with a different shade of eyes (for example, one eye is green, another blue or one eye of a carry, another green), such a phenomenon is known as heterochromia.
In ancient times, the different color of the eyes was considered something mystical, otherworked. Now, modern achievements of medicine makes it easy to explain this phenomenon.
Causes of different color
Researchers still can not give an accurate answer to the question why heterochromia occurs
. The most common theory is that it is simply features of individual development, an unusual natural phenomenon. Nevertheless, the following reasons for this feature are distinguished:- Congenital or simple shape of heterochromia - When the eyes of a different color in humans, with other violations of the visual organ not observed. This is a rather rare form of anomaly. Heterochromia can manifest itself not immediately, and the course of the first two years of the child's life.
- Complicated heterochromia - often appears against the background of Fuchs syndrome. This pathology is characterized by the defeat of one eye, heterochromia is expressed weakly or absent. The reason may be more dangerous states, for example, the development of the tumor process. At the same time, a person will present other complaints;
- Acquired form - Changing the color arose due to traumatization, inflammation, tumors, irrational use of eye drops. Color change can occur, for example, after entering the eye of the smallest particle of any metal. The iris because of this becomes greenish, blue, brown or rusty.
The most banal cause of heterochromium, not related to any diseases and injuries, is wearing color contact lenses.
The modern ophthalmological market is represented by various lenses that can change not only the color of the iris, but the form of pupil.Features of two-color eyes
The heterochromy frequency is approximately 10 cases per thousand. Its main reason is an overly high or low content of coloring pigment. This substance is called Melanin and is responsible for this or that shade of the eye in humans.
The color of the iris consists of several pigments: yellow, blue and brown. The shade of the eye is determined by the proportion of these pigments. Interesting the fact that each individual has its own form of heterochromia, i.e. It is impossible to meet a person with identical manifestations of anomalies. This is not a disease, but a unique feature of a person.
Several varieties of heterochromia are distinguished:
- Full heterochromia - It is manifested that both eyes have a different shade. Most often people with different combinations of blue, can also be one eye of the carial, another blue;
- Sector or partial - Rainbow shell painted several contrasting colors. Most often there are such combinations as a combination of gray, blue and brown. Sometimes there is a blue eye color with white splashes. In most cases, such a form of anomaly is caused by mechanical damage to the visual apparatus or by the suffering disease;
- Central - the color of the iris is characterized by the fact that there are somewhat clearly pronounced multicolored rings.
It is not necessary to treat heterochromium, since the abnormality does not affect the quality of the visual function. Only in rare cases, different color of the eyes is a symptom of ophthalmic pathology.
Famous personalities with heterochromy
Most often there are differences with the full type of heterochromia, but sometimes there are face with partial shape. Famous personalities, distinguished by heterochromy, not so much.
Among them, a composer of Tim Makilrot, actress Jane Seymour, actress Olivia Wilde, Athlete Ilya Kovalchuk, Rock Artist David Bowie, Michael Fletyley Dancer, Boxer Jane Plumber.
Currently, there are almost no information about famous people from Russia or CIS countries.
Animals with different eyes
Multicolored eyes are found not only in humans, but also in animals. It should be noted that different color of the eye is most characteristic of certain breeds. Such Animals include Husky Dogs, Persian Cat, Cat Breed Turkish Angora, Dogs Border Collie, Cats Turkish Wang, Australian Shepherd. This trend is most likely due to the fact that the thoroughbred cats and dogs are derived by artificially, as a result of which various mutations occur.
In Turkey, Angora cats with different eyes are considered the most valuable. This is the so-called "national decoration" of the country.

Heterochromia is when a person has a different color eye. The difference in the color of the eyes in a person is caused by an excess or disadvantage of pigment - melanin. Such a rare phenomenon is found not only in humans, but also in animals, for example, cats. A long time ago, people with different color of the eyes considered the children of the devil, witches, that is, people associated with witchcraft or black magic. They caused fear from ordinary people, but now it is known that the different color of the eyes is not the tricks of supernatural power.
There are two types of heterochromia: the first is complete heterochromia, and the second appearance is partial heterochromia. With complete heterochromy, the color of one iris completely differs from the color of another iris. With partial heterochromia, a person has one part of the iris (eyes) differs from the remaining part of the iris, that is, one eye has two colors. Most often there is a complete heterochromia in humans, less often partial, approximately 4 people from 1 million. .
Heterochromia is a mutation that occurs after the fertilization of the egg. But he fear heterochromia is not worth it. She does not affect the health of a person who has a different color eye. A man with heterochromia sees and perceives colors as well as an ordinary person, but only he has its own individual wint. By the way, heterochromia is more common in women than among representatives of strong sex. It happens that heterochromia becomes acquired. Due to injury or disease (Girshprung disease, Vaardenburg Syndrome), a person acquires a unique phenomenon.
If a person suddenly was born in a poorly educated Middle Ages with multicolored eyes, he had to endure persecution and humiliation all his life, hear curses to his address. Mother of these unfortunate was also very sick, they were suspected of a love connection with an unclean spirit, as a result of which a demonsky child was born. Of course, all these superstitions have nothing to do with reality, just earlier what led to horror, and did not have explanations he was written off on the tricks of unclean strength.
Fortunately, in our time, the eyes of different color do not cause such negative emotions as in the Middle Ages. Scientists working in the field of genetics were able to find out the cause and mechanism for the appearance of this phenomenon. Anomalous iris pigmentation is a genetic disease that is transmitted from generation to generation and manifests itself in random order.
Heterochromia is an amazing phenomenon or illness?
People with different color of the eye constitute only one percent of the total population of the planet. Translated from Greek Heteros Chroma denotes "other color". This rare anomaly is manifested as a result of a mutation occurring after the fusion of the egg cell with a sperm. Different color of the eye arises as a result of a melanin imbalance, which is a pigment with a rainbow shell.
People with such an amazing feature visually perceive images and colors as well as others. Heterochromia It does not impair vision, it is not displayed on human health and allows you to lead the same way of life as in people with eyes of the same color. Interestingly, the eyes of all newborns have the same color, but if the baby is genetically destined to be born with such a highlight, it will manifest itself no earlier than a few weeks.
Forms and types of heterochromia
Scientists use the following classification of forms.
- Congenital - transmitted by inheritance, manifests almost from birth.
- Acquired - arises after a serious injury, is a complication after the suffering disease. It may be a side effect of receiving some drugs.
- Central - the color of the area around the pupils and the color of the iris is different.
- Full - the eyes radically differ from each other in the color of the iris.
- Partial - iris has a green or blue color, as well as on it is noticeable brown splashes.
If this genetic anomaly manifests itself only in changing the color of rainbow shells, there is no need to prescribe medication treatment or conduct operational intervention. As an option, people want to adjust this drawback, you can advise using contact lenses that can give any color to human eyes.
What do psychologists say about this issue?
Nowadays different eye color in humans, as it is called and in which forms it is already a thoroughly known. According to clinical research and observations, heterochromy is much more often arising from female representatives than in men. Psychologists have allocated such common features of the owners of this rare raisher: controversial, elevated capriciousness and stubbornness. It is difficult for people with a "multicolored" look to find an approach, they are very demanding to others, often love to be alone and hide their difficulties and problems. Positive traits include generosity, honesty, kindness and patience.
Among the famous personalities, people with eyes of different colors are also found. This is Mila Kunis, Christopher Uken, David Bowie. With all its genetic nature, heterochromia is not a dangerous disease, which can affect the health and the usual way of life of a person.
The eyes of a man - the mirror of his soul. The color of the eye can determine the character and person. However, there are people, whose eyes are different. Different eyes are a phenomenon marked with 1% of the world's population. This phenomenon in medicine is called heterochromia. It manifests itself in the fact that one eye is partially either completely different from the other in color. This phenomenon is caused by a smaller content in it, compared with another eye, the pigment of melanin. Melain and paints a man. If a person has different eyes, in the iris lighter, the content of melanin pigment is significantly reduced. As a result, it becomes brighter compared to the other.
Why is there such a phenomenon as different eyes? What is the reason that the eyes of a person become different?
If a person has different eyes, this feature is often congenital. However, heterochromia can occur in a person during life. In this case, you should refer to the doctor, because it may be a consequence of various diseases. First, the reason that a person has different eyes is a lack of either an excess of melanin pigment. This may speak about the presence of the following diseases: glaucoma, inflammatory processes of the iris, caused by rheumatism, flu or tuberculosis, as well as the development of a benign tumor in human body. In addition, different eyes can appear both as a person's reaction for medicines and medicines.
Another cause of heterochromia is the late removal of iron or copper fragment during eye injury. In this case, the rainbow shell can change its color.
It can become green and rusty brown. These are the main reasons for which there are different rainbow shells can recover if heterochromia is acquired. For example, if you remove a foreign body during eye injuries or cure inflammatory processes.
Heterochromia has two varieties. It can be complete and partial. Partial heterochromia is manifested in the fact that the person's eye is immediately painted in two colors, that is, one part of the iris will have one shade, and the other will be painted in a completely different color. A complete person is two eyes of different, different from each other, colors.
Many people think that heterochromia is different eyes in a person - can influence his health or perception of the surrounding world. However, this is a delusion, since, fortunately, in most cases, people with such a phenomenon, as different eyes, do not feel any inconvenience and do not have health problems. However, there are exceptions when people with a bright painted iris can develop a chronic inflammatory process. Such a process can negatively affect human vision. Therefore, people even with congenital, and not acquired heterochromia, it is necessary to attend periodically the Cabinet of the ophthalmologist. Perceived the same as usual. More such phenomenon, like heterochromia, are subject to women than men.
Heterochromia is a physiological deviation associated with the fact that human's eyes have different colors. This phenomenon is not widespread, but quite frequent. On average, five people from a thousand have different color of the eyes. Similar deviations are found in animals.
The color of the eye is directly determined by what the number of melanin is contained in the iris. For example, the amount of melanin is less, the way is lighter and vice versa. In the carareg people of this substance in the rainbow shell a lot. Under normal conditions, melanin is distributed between the organs of vision evenly, but there are situations, a different kind of failures, in which the distribution occurs unevenly, as a result of which the iris in each eye acquires its shade.
In ancient times, people struggled, or on the contrary, bowed to the holders of heterochromia, considering their sorcerers or messengers of the Higher Forces. During the Inquisition, the owners of such a defect were tortured, as well as women who gave birth to children with such pathology. Such women were accused of communication with the devil.
Medical justification of heterochromia whereas prosaic. And today, such a feature for someone becomes pride, and someone opposite is shy of such a defect and tries to correct it. Together with this there are a variety of myths associated with the advent of such a defect.
Causes of the appearance of heterochromy eyes
And so, the reason for this phenomenon is an uneven distribution between the eyes of melanin, but the cause of such an effect may be different.
The hereditary manifestation is quite frequent. If one of the parents is the holder of heterochromia, then the likelihood that the child will inherit this feature close to 100%. Not rarely, this pathology is manifested in a generation. However, congenital anomaly is far from the only option.
A different hint of the cornea in the eyes may arise as a result of injury of the eye by foreign object. For example, when the eyes are wounded with a metal chips and, when untreated removal of this particle, a blue iris can purchase a brown or green shade. The acquired pathology of such a plan is called metal medicine.
Fuchs or Wen syndrome. This ailment arises due to inflammatory processes occurring in the vascular shell of the eye. As a result, blurred eye arises and visual acuity is reduced. Gradually, the color of the iris, and in fact, simply clouding, is enhanced. The defeat is most often unilateral, but sometimes bilateral. In fact, it is possible to call this phenomenon of heterochromy with the stretch, since there is still not a change in the color of the iris, but toasting.
It is important to remember that the finally the color of the eyes in humans is formed to two years of life. Therefore, it is important that parents watched the child, and if the effect of different color of the eyes is seen, it is necessary to contact an ophthalmologist.
Types of heterochromyia eye
Heterochromia is divided into three types:
Complete when the eyes are completely different in color from each other;
Partial when the iris is painted unevenly, fragments. Sometimes the effect is manifested in the form of random spots, sometimes the iris, as it were, is divided into half;
Central when color change is observed only near the pupil.
Does heterochromia affect the patient's well-being?
The heterochromy itself does not affect the state and well-being, but it is worth understanding that its manifestation is not always the effect of manifestation of genetic predisposition. The difference of the eye color may be a signal of serious diseases, such as:
Vaardenburg Syndrome, which in the launched cases is able to lead to the appearance of gray strands in young age and loss of hearing;
Neurofibromotosis, expressed in the threat of the development of bone anomalies. This disease begins with changes in pigment, which later develops into tumor education.
The ophthalmologist will determine the nature of the color change in the iris and in case of danger, will send a patient for an additional examination.
Myfs accompanying heterochromy
This deviation is permanently accompanied by various myths. And if in ancient times everything came down to the fact that the eyes of different color, it is more otherworldly, today the creators of the myths compete in the sophistication of information noise that balances on the verge of facts.
People with heterochromy Dongtoniki
It is a myth. Daltonism is not the result of the number of melamine in a rainbow shell. People with this pathology distinguish colors as well as people with "ordinary" eyes.
Different eye color leads to the fact that both eyes in the eyes of different
It is also a myth. The optical power of the eye does not depend on the color of the iris. Patients with heterochromy can have both excellent and bad eyesight, both in the double version, and each eye separately. It all depends on various factors.
All owners of heterochromy nervous and unlike
There is some truth. Some children who are eye owners of different colors begin to closes in their school years due to ridicule or excessive attention of peers. This is the cause of psychological instability. However, there is a lot of the parents. If the child is explained to convince him that there is nothing special in the eyes of different colors, it will be easier to treat unfulfilled attention to myself.
People with heterochromia are more susceptible to diseases of the eyes and diseases in general
It is also a myth. No data was not officially recorded that this deviation affects the immune system and somehow contributes to the development of disease. And all the stories in this regard are most likely based on the fact that the color of the iris can be a signal of a developing disease. For example, Vaardenburg or Neurofibromotose syndrome.
How to get rid of heterochromy?
Many are wondering whether it is possible to get rid of such a deviation and how to make it so that both eyes had the same color of the iris. Ophthalmologists believe that if there are no symptoms of a dangerous disease, interference in the form of surgical and drug treatment is not required. On the contrary, it is even dangerous.
Unfortunately, in some cases heterochromia, when it is partial, is expressed in a very ugly perspective. In these cases, a therapeutic treatment or surgical intervention is applied. Unfortunately, not always successfully undergo changes.
The least dangerous option is to change the color of the eyes using contact lenses. Here are suitable both simply colored, without diopters and correctional. The choice of such products is very large, the main thing is to choose the option and comply with the rules of wearing CL.
Summing up
Heterochromia - phenomenon is quite frequent, but not widespread. If we talk about this deviation, as a genetic phenomenon, and not as a symptom of other ailments, in principle, this deviation is not dangerous, and does not carry any discomfort in terms of quality of life. The only drawback is that the different color of the eyes strongly attracts the attention of others. Although for some, it is rather plus.
