Eye color is believed to be a hereditary trait. However, the color scheme may 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, in children who are born with brown eyes, the eye color will remain the same, unchanged, if they are healthy.

In an adult, eye color can change under the influence of lighting, hormonal changes, moods, stressful situations, colors of clothing or makeup. This does not mean that the eyes will necessarily completely change their color - just that the shade will become a little lighter or darker. The frequency of this color change varies from person to person.

It happens that some people have different colors in their left and right eyes. This unique feature is called “heterochromia”. It can be either congenital or acquired.

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

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

There is no need to worry if eye color changes gradually, under certain conditions. This happens because the iris contains muscles that can constrict and dilate the size of the pupil. Surely everyone noticed that when reduced level In bright light, the pupil becomes large, and in bright light, on the contrary, it narrows.

The pupil also decreases in size when a person focuses on close objects, such as when playing on the 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 yet fully figured out why some people's eyes can change color, while others cannot. But they came to the conclusion that the endocrine and nervous systems 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 was not observed before, this may be a sign various diseases, in this case, you should contact an ophthalmologist who will determine the cause of such sudden changes.

Methods for artificially changing the color of the iris

You can change the shade of your eyes yourself by using some techniques:

A person's eye color can change throughout the day or throughout his life, and this is not surprising.

Eyes, like the mirror of the soul, can tell a lot about character and inner world their owner. Human chameleon eyes - rare phenomenon Among the common colors are brown, blue, gray and green. Thanks to the ability to change its color, the chameleon camouflages itself with its surroundings, which allows it to hide from danger, hunt insects and survive. The nature of changes in eye color in humans has not been fully studied and therefore continues to attract the attention of scientists and doctors.

Mechanism of color change

In people with chameleon eyes, the shade of the iris changes, and the change can be either dramatic, from light blue to brown, or less obvious, for example, from gray to gray-green. Great rarity - brown colors, changing color to lighter, since the gene responsible for dark tones is dominant. Such metamorphoses most affect those with an indeterminate color, such as gray-green or gray-blue.

Why does the shade change?

For some people it depends on the lighting, for others it depends on emotions and mood. It is impossible to unambiguously determine the cause of the change in the color of the iris. This may be a consequence of one or several factors, including:

A child is born with a blue iris.

• Growing up. Typically, babies are born with light blue eyes, which may change to a darker shade over time. The pigment melanin is responsible for this transformation, which accumulates to required quantity. The higher the melanin content in the iris, the darker the shade becomes.
• Work of endocrine and central nervous systems. Pathologies in their work affect the melanin content in the layers of the iris, which provokes a change in color. There is an assumption that the color of the iris also depends on the concentration of hormones in the body.
• Emotions. Excitement, stress, delight, tenderness, fear, surprise, anger, sharp changes mood - all this can affect the change in the shade of the iris. It is noted that when a person cries, the color of the eyes changes and becomes more saturated.
• External factors. Chameleon eyes try to adapt to change environment, for example, changing time of day, temperature, atmospheric pressure, weather conditions, various artificial lighting.
• Pupil width. A dilated pupil creates a misleading impression of true color because it covers a significant portion of the iris.

Abnormal changes

Heterochromia is a different coloring of the iris, not a disease, so there is no need to worry or be afraid of it.

There is a phenomenon in which one eye of a person differs in color partially or completely from the second. This phenomenon is called heterochromia, or in common parlance cat eyes, is transmitted genetically and manifests itself in one out of a hundred inhabitants of our planet. Celebrities with heterochromia include Kate Bosworth, Demi Moore, Mila Kunis, Alice Eve, Henry Cavill, David Bowie and others.

A sharp change in the color of the iris, which is uncharacteristic for a person, may indicate a disease and in certain cases be a symptom inflammatory processes, traumatic injuries, leukemia and other diseases. To eliminate the possibility of vision deterioration, it is strongly recommended to visit a qualified specialist.

However, there is no need to sound the alarm; a uniform gradual change in the color of the iris does not mean that a person has dangerous diseases. In most cases, this phenomenon is individual in nature and does not need to be considered as a disease. Many scientists consider the ability to change the shade of the iris to be an acquired human skill, and not a sign of ophthalmic abnormalities.

Sometimes this shade is found in Syria, among Ashkenazi Jews, Tajiks and among the mountain Pamiris. By the way, in 2008, geneticists at the University of Copenhagen discovered that the blue iris is a mutation in the gene that arose 6–10 thousand years ago. Dr. Eyberg noted that " initially everyone had brown eyes , and the mutation reduced melanin production.” According to scientists, this first happened in the north-west of the Black Sea region.
