It is believed that eye color is a hereditary trait. However, the color scheme can be completely different between parents and children. In addition, eye color can change over time in both a child and an adult.

Eye color depends on the amount of pigment called melanin produced. Melanin is distributed in the anterior layer choroid eyes. How more content of this pigment in the front layer, the darker the eye color will be, but if there is too little melanin, then the eyes will have light shade. The amount of melanin remains approximately the same throughout a person's life. Sometimes melanin is not produced at all, as a result of which eye color is inherited.

Almost all Caucasian newborns have blue eyes. But their color often changes within six months. This happens because at birth the child has too little melanin, but with age, the amount of pigment increases. However, babies who are born with brown eyes, the color of the eyes will remain the same, unchanged, if they are healthy.

In an adult, eye color can change under the influence of lighting, hormonal changes, mood, stressful situations, colors of clothes or make-up. This does not mean that the eyes will necessarily change their color completely - just that the shade will become a little lighter or darker. For each person, the frequency of this color change is different.

It happens that in some people the color of the left and right eyes is different. This unique feature is called heterochromia. It can be both congenital and acquired.

Also, the color of the eyes becomes darker with age, because. the iris of the eye thickens.

Thus, the same person can have blue, blue or gray eyes. It depends on the environment, the weather or his inner state.

Do not worry if the color of the eyes changes gradually, under certain conditions. This is because the iris contains muscles that can constrict and dilate the size of the pupil. Everyone must have noticed that reduced level In bright light, the pupil becomes large, and in bright light, on the contrary, it narrows.

The pupil also shrinks when a person focuses on nearby objects, such as when playing on a computer, watching TV, or reading a book. When the pupil size changes, the color of the eyes changes slightly, as the pigments in the iris of the eye shrink or diverge.

Scientists have not fully figured out why some people's eyes can change their color, while others do not. But they came to the conclusion that the endocrine and nervous system have a great influence on the color of the iris, since with pathologies of these body systems, the process of melanin formation changes, as a result of which a change in the shade of the eyes is observed.

If the color of your eyes has changed dramatically in a short period of time, which has not been observed before, this may be a sign various diseases, in this case, you should contact an ophthalmologist who will determine the cause of such drastic changes.

Ways to artificially change the color of the iris

You can change the shade of your eyes yourself by applying some tricks:

The color of a person's eyes can change throughout the day or throughout life, and this is not surprising.

It always attracts attention and interest of others, as the process of changing the shade looks amazing, extraordinary and magical.

Such individual characteristics cause admiration, and sometimes fear, because society is afraid of the unknown and atypical. In some cases, you can notice how the color of the iris has changed dramatically in a short period of time.

What are chameleon eyes

Eyes that change color are not very common, but it is useful to know what they are called. The term comes from the animal chameleon, which, depending on the environment, can change its color, this is due to disguise. In some people, the shade of the iris becomes different. Of course, this has nothing to do with trying to blend in with the environment, but just a physiological feature.

Scientists are still studying the question of why the eye color changes, but they have only a few assumptions.

Hue human eye depends on the content of melanin in it. This is a pigment, and the more it is in the upper layer, the darker the iris. If it is absent, then the eyes acquire a blue tint. Thus, there is an assumption that the amount of enzyme in the iris may vary, which provokes a change in the shade of the eyes. One of probable causes- due to malfunction endocrine system. Genetic proof and inheritance has not yet been found. There is no exact data from which this happens in all cases, there are only assumptions.

Species in changing the color of the iris. People's eyes change in different ways.

There are three main types of changes:

• Hormonal disorders It's like one of the theories. If it is noticed that the eyes have changed color, and this was not observed before, then it is better to be examined by an endocrinologist.
• Age. Many, probably, noticed that newborn children for the most part have blue eyes of a very pleasant shade. There is still not enough melanin in the iris, and it was not needed in the womb, since it was not required to protect from ultraviolet radiation. By about 6 months, the true color of the eyes appears. Further there is a thickening of the iris, so the color may become more saturated. However, with age, the effect of fading occurs. Brown eyes may become more faded, blue eyes may turn gray. The reasons for this are the loss of melanin with age and health problems.
• During the day. This is the most interesting type of eye color change, which certainly attracts attention. Hue depends on the lighting, the size of the pupil, and sometimes the mood of the person. At the same time, the eyes can shimmer in different shades and even differ if you look at them under different angle. It is with such eyes that superstitions are associated.

Good to know: you should not ignore changes in pigmentation, especially if this has not been observed before. Sometimes it speaks of hidden diseases.

Features of changes in chameleon eyes

It's amazing when you think that a person grey eyes, and then you realize that they have become green or bright blue. Sometimes the shade changes slightly, and you can notice it only with constant communication with a person. However, there are cases when the color changes quite brightly and in a short period of time or in large ranges - suddenly browns turn green.

The color of the eyes can become different not only due to the work of the endocrine system, but also due to nervous experiences. Change of mood, fear, desire - all these emotions are reflected in the color of the iris. No wonder they say that the eyes are a kind of mirror that can tell a lot about the physical and mental state person.

Such features are not considered a pathology if they were observed initially, that is, from childhood.

What do chameleon eyes mean

Many beliefs are associated with eyes that change their color, someone is looking for a special meaning in them. The people believed that such people had a special gift and witchcraft power, and even feared them.

Attribute to such people and some features of temperament and behavior. It has been observed that eye color is partly associated with certain personality traits. But with chameleons, everything is much more complicated.

Often, people with similar eyes have the following behaviors:

• Impulsiveness.
• Changeability of mood.
• Bright inner world.
• Expressed individuality.
• Behavior, speech also changes with the shade of the iris.

Surrounding people are often interested in the question: can people change eye color at will. Most likely, this is at the level of myths, although this fact cannot be ruled out, it is likely that someone is able to do this. If suddenly the iris abruptly changes from brown to green, it looks very impressive. Sometimes for this it is enough to change the angle of illumination so that the eyes acquire a different shade, which is what the owners of chameleons use.

It is interesting
Babies that have recently come out of the womb have blue eyes. This is due to the fact that melanin is produced, but very weakly. Upon reaching the child three months his eyes change because the color pigment reaches its peak of development.

In the world, 2 types of abnormalities associated with the production of melanin have been found. Albino man looks at the world through blood vessels because it has no melanin at all. The irises of such people are pink or red. The next unique consequence is called heterochromia, when the iris of one eye differs in color from the other.

Experts notice that eye color often changes after illness. In most cases, they darken, brighten or switch to similar colors. So, blue eyes acquire gray shade, brown - black, and green can be replaced by light brown.

Study your diet carefully

Food is closely related to all processes in the body, including the production of melanin in the eyeballs. The hormones norepinephrine and serotonin have the ability to dilate and constrict the pupils for a certain period of time, as a result of which the eyes either darken or brighten. Radical changes in your daily diet will not change the color of your iris much.

If you like to diet, make a menu based on individual needs. Include foods that contain the optimal amount of these hormones in your diet. Eat oatmeal, hard cheeses, natural chocolate. Try to eat more oranges, melons, bananas, porcini mushrooms, green vegetables. Sport also promotes the production of serotonin, you may need to change your rhythm of life to a more active one.

Monitor your own emotions

When a person rejoices, his pupils dilate and become distinct and bright. If you are angry or sad, the iris darkens. With an endless and prolonged stream of tears, the shell of the eyes brightens, becomes transparent, and the red vessels contrast with the natural color of the eyes, so their shade changes.

Carry out regular cleansing of the body with decoctions of plants

People who change eye color in this way, unanimously claim the effectiveness of the procedures. Medicinal herbs affect the hormonal background, especially for women. Such changes provoke a change in the color of the iris to contrasting shades. Your eyes may be blue, but with prophylaxis and herbal cleansing, they will go to the blue or green side.

Make an infusion of chamomile flowers, cornflower, licorice root, rosemary and mint, consume with meals, but at least 5 times a day for two weeks. Modern tea boutiques, pharmacies and shops proper nutrition offer all these infusions in a ready-made version. You just have to buy the powder and dilute it with warm water.

Use lenses that are sold in any pharmacy

The variety is amazing, you have the opportunity to make your eyes not only brown, green or blue. Manufacturers produce purple, gold, silver, yellow and even black lenses, the choice depends on personal preferences. It is important to carefully read the instructions so that "artificial eyes" serve you faithfully long years. Be sure to use a cleaning solution and remove your lenses at night.

Get your makeup right

If you are putting on a discreet and natural make-up, go for bright colors. Shadows, eyeliner, mascara and false eyelashes of various colors will create the illusion of a different shade of eyes. They shade the iris, give it brightness and unusual colors.

Color makeup works wonders! To make eyes with a blue tint, use golden and copper shadows, purple eyeliner will give the iris a green tint, and blue can make the eyes brown, almost black.

3. Don't follow the advertising signs and banners on the Internet that hypnosis changes eye color. The iris takes on a different shade only during the influence of the hypnotist on your body, but at the end of the session, the result immediately disappears. Again, the hypnotic effect is directly related to hormones, but the result is short-lived.

Important. After certain procedures at home, have you noticed a sharp change in eye color? Contact an ophthalmologist immediately! Meditation is a long-term procedure, one day the iris will not change. As for drops and infusions medicinal herbs, they change the hue to a small extent.

In other cases, a dramatic change indicates an infection of the eyeballs, which can adversely affect your health. Come to the understanding that it is extremely difficult to change brown eyes for blue ones, you need to work on yourself for a long time.

Tired of the monotony and want to change your appearance, starting with the color of your eyes? Purchase drops at the pharmacy, after consulting with your doctor. Brew herbs and drink them daily. Does not help? Choose the right lenses and wear them whenever you want, but be sure to take them off at night. Engage in meditation, visualize all the processes in the body. Take care of yourself and stay healthy!

Video: change eye color to blue

It's hard to believe, but ten thousand years ago, all people on earth had the same color eyes - brown. Later, the gene responsible for eye color began to mutate. This led to the fact that the production of melanin in the iris of the eye decreased. The more of this substance, the darker the eyes. Less melanin resulted in blue eyes.

This discovery was made in 2008 by the Danish scientist Hans Eiberg. After studies conducted under his leadership by a group of scientists from the University of Copenhagen, it was precisely established that the iris “gives out” a different eye color from the saturation of melanin.

Primary eye colors

There are two primary colors - blue (in its range gray, blue, blue) and brown (brown, green). Brown eye color is dominant. However, the majority of the world's population is born with blue or grayish eyes, and only then do they change their color.

This is due to the fact that at birth melanin is completely absent in the iris. Only some peoples of Asia are born immediately with dark color eye - scientists explain this by the features of the gene structure. With a change in the pigmentation of the iris of the eyes (and this just depends on the saturation of melanin), the color also changes. Scientists have found that the final color of a person's eyes is formed by 2-3 years of age.

We know from high school biology class that eye color depends on a certain set of genes. Who at school did not solve the problem of determining the color of the eyes of a child whose mother has brown eyes, father with blue, grandparents have gray, blue and green.

What determines eye color

However, Dutch scientists conducted a study that denied the existence of a certain gene, which determines the color of the eyes and which is inherited.

Volunteers were involved in the experiment conducted by scientists, including many twins and their closest relatives. In the final report, the scientists noted that the mononucleotide chains in the gene, which was considered hereditary, strongly affect the final result, but they are not directly related to eye color variations.

That is why in school biological problems the solution looked like a certain percentage possible color the eye of a child, but not an absolutely accurate definition.

eye color disease

In some people, the iris changes its color depending on the weather, lighting, clothing color, and even the state of the body. Why this is not characteristic of all people - specific answers to these questions have not yet been found.

But there is some research in this area as well. Since ancient times, a method for diagnosing human diseases by changing the color of his eyes has been known. It's called iridology. In China, India, diseases were determined in this way three thousand years ago. Hippocrates also knew about him.

The first of the scientists of our time to seriously study this method was Ignacy Pecceli, who lived at the turn of the 18th and 19th centuries near Budapest. Once, as a child, he knocked down an owl with a stick.

When I began to lift it, I saw that a dark streak appeared in the eye, which corresponds to the broken paw. The boy took the owl home and began to treat her broken leg. As I recovered, the band disappeared.

Later becoming a doctor, Ignacy Pecceli began to study this diagnostic method in earnest. In parallel with him, a pastor from Sweden, Nils Liljekvist, worked on the same. He deduced a whole theory of recognizing various diseases by changes in the iris of the eyes.

Soviet scientists conducted research on this method on the basis of the University of Friendship of Peoples. P. Lumumba. In parallel, they found that the color of the iris changes not only depending on certain diseases. This can happen, for example, with age, when the work of all organs slows down, including the production of melanin.

Another reason could be nutrition. For example, if you consume daily foods rich in beta-carotene, selenium, vitamin A, melanin production will increase.

Traditionally, it is believed that the color of our eyes is a hereditary phenomenon. However, the genetics of color is very complex and can vary greatly between parents and children. It is believed that eye color can change in children during the first year of life.

The eyeball, as you know, consists of three shells: outer, middle and inner. The outer shell, as a rule, is the densest of all and has a transparent part of it - the cornea. The middle membrane is vascular, formed by the ciliary body, the choroid itself and has important element for eye color - the iris - a flat ring in the center of which is the pupil. Depending on how much melanin pigment is contained in the eye cell, and how it is distributed over the surface of the shell, the color of our eyes depends. In addition to melanin, the color is influenced by the vessels and fibers of the outer shell.

In the posterior layer of the choroid, as a rule, there are many pigment cells and this layer is always dark. The only exceptions are albinos, who have no melanin pigment at all, so their eye shell is transparent. But as soon as light enters them, the color of the albino's eyes appears red.

Melanin is responsible for eye color

Depending on the amount and distribution of melanin in the anterior layer of the choroid, the color of the eyes varies. If there is a lot of pigment and its density is high, then the eyes will have brown or yellow. If this pigment is not enough in the anterior layer, then the back layer - brown - will be visible through the fibers and vessels, and due to light scattering in the stroma - the fibrous tissue layer - the eyes will acquire a blue or blue tint. There are no blue or blue pigments in the shell of the eye itself.

Otherwise, the case with green eyes. The owners of this color make up only 2% of people on Earth, and this is due to heredity. It is known that in the Middle Ages, women with this color were called witches and massively burned at the stake. The amount of melanin in such eyes is negligible, and the back layer has a blue tint, and in the outer layer, due to a special pigment, a yellow and light brown tint is distributed. As a result of scattering in the stroma with blue, a green color is obtained.

Most rare color eye - lilac . It is almost impossible to meet the owners of this color. Scientists believe that this color is associated with the appearance of a double row of genes. Only 7% of people are known with this color, and the famous actress Elizabeth Taylor also falls into them.

Can the color change?

It is believed that eye color can change in children during the first year of life. This is due to the fact that at birth such children have little melanin, but gradually its amount may increase. However, if a newborn has brown eyes, then with good health they don't light up.

In an adult, the color of the eyes can also change. But since eye color is determined by genes, this is only due to diseases. The effect of hormones in the body can also be the cause, but the shade can only become darker. A change in shade is also possible under the influence of lighting, environment, clothing and makeup.

The pupil diameter varies from 2 to 8 mm depending on the illumination, nervous regulation or the action of medications. Normally, the pupil constricts in bright light and dilates in low light. When the size of the pupil changes, the pigments in the iris shrink or diverge, which causes a change in color.

How can you change eye color artificially?

1. One of the most popular ways is colored lenses. But their service life is limited, and at first discomfort is possible.

2. Eye drops containing analogs of the hormone prostaglandin F2a. But at long-term use nutritional deficiencies may occur eyeball. Meanwhile, the color can only change from light to dark.

3. Laser correction colors are one of the youngest and most expensive methods, the long-term consequences of which are not yet known. In addition, such an operation is already irreversible.

4. Surgery- a case in which an implant of any other color is inserted into the eye. The operation is expensive and can cause significant harm to health.

Melanin - protector from burns

The amount of melanin affects not only the color of the eyes, but also the hair and skin. Freckles, moles, nevi and other "spots" owe their appearance to him. At the same time, everyone's favorite sun tan is a screen produced by melanin to protect against dangerous ultraviolet rays.
