Eye color changes with mood. Why eyes change color: what is the name of the disease

Eye color (as well as skin and hair tone) is largely determined by the amount of melanin in the human body. One of the functions of this pigment is to protect against ultraviolet radiation. There are no UV rays in the womb. Therefore, the content of melanin in newborns is minimal. In the first months of life, its amount increases, respectively, the color of the eyes of babies changes (many babies are born blue-eyed, and with age this color changes to darker).

Age changes

If we talk about how much the color of the eyes changes more or less accurately, then we can name the age of about six months. Usually, by this time, the eyes acquire a color that practically does not change with age.

Another mechanism for changing the color of the iris is not chemical processes associated with pigments, but in an optical phenomenon. The iris of the eye becomes larger with age (of course, this applies only to children). Changing the size of this shell leads to darkening of the eyes.

As adults, some people sometimes develop dark spots on the iris, which differ from the main tone in more dark side. These spots are "analogues" of freckles.

As we age, melanin production decreases. As a result, the hair turns gray, and dark eyes become lighter. At the same time, the iris in old age becomes much denser and less transparent. Therefore, bright eyes in older people darken. This is why eye color changes with age.

Daily color changes

Can eye color change throughout the day? Pigmentation doesn't change that quickly. However, our perception of colors depends on a number of factors. The main ones are the size of the object and the background. Therefore, the color of the iris of the same person in the light of a dim lamp at night and in the light of the sun can be perceived differently.

In addition, bright light constricts the pupil of the eye, which leads to the fact that visible part iris enlarges and appears brighter. In the dark or in poor lighting (or under the influence of alcohol or emotional factors) the black pupil becomes much wider, and this, against the background of dim lighting, leads to a visual darkening of the eye.

With an increase blood pressure blood vessels, located in the area of \u200b\u200bthe eye, overflow with blood, while the whites of the eyes turn red. Sometimes the vessels burst, which leads to temporary bruising (eyes "bloodshot"). Such a change in the background on which the iris is located can lead to a sensation of a change in its tone.

Eye pigmentation does change with age. First of all, this is due to a change in the concentration of melanin. All visible changes in eye color during the day (or several days) are an optical illusion.

Each of us has his own distinctive feature, namely different colour eye. Brown, blue, gray and green eyes owe a special pigment to melanin, which works real miracles, coloring the eyes of children and adults. The shade of the eyes depends on the amount of pigment, if it is more, representatives of dark skin are born and brown eyes if less - to be a blue-eyed person and with a light skin.

Studies have shown that the values of melanin in an adult do not change even after time has passed. However, there are exceptions, they depend on unusual conditions and conditions of the body that affect the iris:

diseases of the organs of vision;
application eye drops;
change in hormonal status;
natural and artificial lighting, makeup, clothing color;
even emotional condition, whether it be rage and, conversely, pleasure, can adjust the color of the eyes.

Changing the color of the iris in infants

As soon as a newborn is born, he may have brown or bright blue eyes. If everything is more or less clear with the first babies, then the parents of the blue-eyed are interested in what range the organs of vision of their beloved child will be painted later.

Yes, yes, this is not a joke - by the age of 1, a child's eye color may change several times, this is due to the participation of melanocytes in protective function from ultraviolet rays. As soon as the baby is born, his eyes have nothing to protect from yet, but as they adapt to external conditions pigment is produced faster and more.

However, doctors do not guarantee that even after 1 year of life, the shade of the iris will not change in the child again. No one has yet canceled genetic heredity, so you should not draw hasty conclusions.

It is known that the deadline for changes to affect children is 10-12 years. Subsequently, if the iris acquires a different color, this is more often associated with diseases and abnormalities in the functioning of the organs of vision.

Causes of eye color changes in adults

It is wrong to say that an adult's eye color will change dramatically; rather, a correction by one or two tones occurs. In which direction changes can occur is also a mystery, there is no one direction.

If an adult is healthy, the color of the eyes changes for quite understandable reasons:

Aging. With age, cell growth and their renewal slow down, the body can no longer work at full capacity, this also applies to the production of melanin. Accordingly, dark brown, almost chocolate eyes become light, and bright greens acquire a shade of faded greens. Reverse picture due to age restrictions also occurs, but much less frequently. Experienced ophthalmologists explain the darkening of the color of the eyes due to the thickening of the iris, which, in turn, loses its former transparency.
If others say that the color of the eyes changes during the day, then the matter is in the lighting and background palette. For example, one has only to put on a blue blouse, as cornflower blue eyes sparkle with an amazing tint. Cloudy and sunny weather also set their own rules.
individual light perception. Each person sees colors in his own way, because the organs of vision, guided by the assessment and analysis of the brain, only convey what they see. Therefore, there is nothing surprising in the fact that one color may seem juicy, while another is ordinary and faded, no.
Depending on the emotions experienced and the time of day, the pupil can either narrow or expand. Narrowing is always observed in bright light, the iris becomes darker. In the dark or when a person is angry, the pupil relaxes and dilates, the hue brightens.
The iris is filled with varying amounts of blood. Entry into the organs of vision of a larger volume of blood provokes darkening.
Food is also not to be missed. The abundance of tyrosine, beta-carotene, selenium, vitamin A and lycopene in the daily consumed food significantly increases the production of melanin.
Change hormonal background. Before referring to this reason, you should take tests for hormones, and each one is taken at a certain period. monthly cycle(when it comes to women). The color of the iris undergoes changes, but not drastic. Doctors note dramatic changes only when a woman is pregnant, experiencing menopause or very nervous.
The previous reason also arises due to long-term use eye drops on a hormonal basis. By the way, such experiments are fraught for the body as a whole, so consult an ophthalmologist.

Nature has made us all different. FROM different color skin, hair, eyes. A person is a set of different genetic characteristics that leave an imprint on his appearance, character, health. There is such a thing as chameleon eyes. It's not that common, but it's not uncommon either. This phenomenon means that the color of the eyes may change depending on the lighting, weather conditions, things put on a person and a color environment. It's not a disease, it's just a feature human body which does not appear to everyone. In the photo you can see the same character in different conditions that affect the color of his eyes, and understand what kind of phenomenon it is.

What determines eye color

Eye color determines the amount of melanin, a substance present in the iris. If there is a lot of it, then the eyes will be dark, if not enough, then light. If melanin is absent, then such people are called albinos because of the transparent color of the eyes with reddish streaks of blood vessels, as in the photo. A person only by the age of 3 receives specific color eye when a stable amount of the substance appears. Small children are all light-eyed. The amount of melanin you have is determined only by the factor of heredity, it cannot be changed.

Person's character

It is believed that a person with chameleon eyes has typical character traits. If the color changes under the influence of mood, then such people are most likely very changeable in all their manifestations. But such people most often adapt more easily to any life troubles, changes and survive even in the most incredible conditions. Their eyes indicate that they will not be in sight, rather they will remain in the shadows, but at the same time they will confidently go in the right direction.

Color change options

Chameleon eyes are different, they are unique like any person on the planet. In most cases, they change from a lighter tone to a darker one within the same color. For example, in neutral weather, be transparent blue, in clear weather - bright blue, and in cloudy weather - blue-gray. Good example presented in the photo. A person with such changes is not so noticeable, and it is not so easy to understand that it is. But if the eyes of a chameleon change color from blue to brown, then this is very noticeable with the naked eye.

Is this the norm

Scientists and doctors do not consider chameleon eyes to be something out of the ordinary. It's the same idiosyncrasy like hair color, for example. Some have a non-uniform color, it can have one tone along the contour, and another tone closer to the pupils. Moreover, all this can vary from time of day, circumstances and color environment. A person with such eyes is no better or worse than others. The fact that many consider such people to be potential soothsayers and psychics is more fiction and superstition than truth. It doesn't provide any benefit other than the visual effect that people with such changing eyes produce.

When to beware

If you have always had a stable eye color and suddenly your eyes have changed a lot in a short period of time, then this moment should alert you and send you to see a doctor. It is likely that nothing terrible will be found, but still it is better not to miss this moment. Taking good care of your health will help you avoid potential diseases and stay healthy.

Otherwise, people with chameleon eyes have nothing to fear, they are absolutely normal and complete. Just for them, nature has prepared a small surprise in the form of changing eye color from time to time. This allows such people to always be different, look unique and be unlike anyone else. What is laid down for us by nature is our individual code, which we do not need to try to change. After all, interfering in the affairs of nature, we often harm ourselves.

In most cases, a change in eye color does not mean anything bad and is regarded as a curious observation.

There are two main eye colors - conditionally blue (blue, gray, blue) and conditionally brown (brown, green). The former are recessive, the latter are dominant. That is, conditionally brown (and vice versa) cannot be obtained from conditionally blue over the course of life. And within the limits of one's own color, during a lifetime, people's eyes usually brighten, some faster, some slower. For very few, the color of the iris (within the color limits) can change depending on mood, lighting, and interlocutor.

Eye color depends on a pigment in the iris called melanin. The amount of melanin determines the color of the eyes. A large number of of this pigment creates dark eyes(black, brown and light brown), and a smaller amount forms light (green or blue).

Albino people have red (pinkish) eyes due to the lack of melanin in the iris. Since it is transparent, the blood vessels of the eye are visible through it.

All people are born light-eyed, and the final eye color is formed in a child by 2-3 years, when the melanin enzyme appears.

Eye color becomes darker as the child grows older. Think of blue-eyed newborns whose eyes turn grey, green and even brown as they age. Darkening of the eyes is associated with the accumulation of melanin.

The amount of melanin is determined by heredity. There are significantly more dark-eyed people in the world than light-eyed people, and the reason for this lies in the genetic dominance of traits associated with large quantity melanin. Therefore, if in a family one parent has dark eyes and the other has light eyes, their children are more likely to have dark eyes.

People with light (blue, gray, green) irises are subject to the greatest fluctuations in eye color. As you know, we see reflected light, and the color of objects in the surrounding world is determined not only by their intrinsic properties but also the surroundings. Therefore, if you carefully monitor the color of the eyes, you can find that the color of the eyes changes depending on the color of clothing, cosmetics, environment.

Some people observe that their eye color changes if they get sick or are in stressful situation. How this happens is not known for certain, but some clinical observations suggest some possible mechanisms.

There is also Horner's syndrome - paresis sympathetic innervation on the face. The color of the eyes of patients with Horner's syndrome becomes lighter. This means that the color of the eyes is also under the control of the nervous system. In addition, the clinic knows some rare inflammatory diseases eye - Fuchs syndrome, Posner-Schlossman syndrome - in which the iris acquires a greenish tint. Often, these diseases affect one eye, resulting in heterochromia, a difference in eye color in one person. There are also congenital cases of heterochromia.

If the process of color change is long and gradual and affects both eyes, then you should not be afraid of this.

If the eyes have changed color significantly in a short period of time, you need to go to the doctor to make sure that everything is fine with your eyes.

Research suggests that eye color indicates certain characteristics of your personality.

People with light blue eyes show patience and perseverance, and people with dark brown color, despite their inherent impulsiveness, cope better with periods of crisis.

People with blue, green or gray eyes are much more likely to develop skin cancer.

It is also known that eye color leaves a certain imprint on the impression of a person as a whole. It is not for nothing that such expressions as "cold look" or, conversely, "warm" appeared. But the reason why a person is born with eyes of one color or another, scientists, it turns out, discovered just the other day.

Brown, green, blue, grey. However, there is such a phenomenon when the eyes can change their color. It is extremely rare that there are cases when they are able to undergo such a transformation. After all, it is known that the brown color of the eyes is the most, one might say, the strongest of the existing shades, the overwhelming other colors are responsible for it. On the contrary, the eye is the most unstable and most susceptible to transformation. Eyes that change color are called chameleons.

Why is this word used in relation to them? It is known that a chameleon is a creature that can change its color in critical situations. For example, in the forest, hiding from predators, these animals turn green to blend in with the greenery. In the deserts, chameleons change color to a sandy color. Thus, the animal cannot be distinguished among the sand. This ability was given to chameleons for the sake of salvation, for the sake of survival in

As for the color of the eyes named after this reptile, some people change their color depending on their mood, others - depending on the lighting.

Until now, the nature of the origin of this has not been fully studied. However, there are cases when the eyes begin to change color from some kind of disease. But in such cases, usually chameleon eyes begin to acquire a yellowish tint. In this, in principle, there is nothing mysterious. But what about the rest of the cases where people from birth have this feature? Many scientists, doctors still disagree.

Chameleon eyes are very beautiful, but it used to be that their owner was associated with the devil. Some people are even willing to pay a lot of money for an operation that teaches the body to change eye color. It is difficult to say that such operations are effective. After all, as you know, the nature of the origin of this feature has not yet been fully studied. With the help of special manipulations, you can only achieve a change in the shade of the eyes, which will remain with you forever.

Only a few of us have chameleon eyes. The nature of such individuals is usually very changeable, impulsive. Gray-brown-green eyes usually indicate indecision, some disorganization of their owners. But such individuals are usually ready for anything, they have well-developed adaptive properties.

Girls with chameleon eyes usually have some difficulties with makeup. It is difficult to choose shadows if you know that at any moment your eye color can change. With bright shades, it's definitely not worth the risk. Such colors most often do not go even to those who have eyes of a constant shade, not to mention the owners of such distinguishing feature like eyes that change color. The color scheme of eye shadow should be as soft and light as possible. It will only emphasize your unusual appearance, draw attention not to your bold make-up, but to your bewitchingly beautiful eyes.

Chameleon eyes are truly amazing!
