Does heterochromia in humans have a disease or a piquant feature?

Not for nothing since ancient times, people considered the eyes a mirror of the soul. Many superstitions and omens, proverbs and sayings were associated with their eyes. However, with the progress of progress, many ancient prejudices have disappeared. For example, they can include a phenomenon such as heterochromy. In humans, it is observed quite rarely and manifests itself in the fact that the color of the iris on the right and left eye differs from each other in color. The name consists of two Greek triplets: "hetero" - "different" and "chrome" - "color". Once heterochromia, the causes of which are not clear even now, was considered a serious ailment. The doctors prescribe to the patients compresses from herbs, lotions and even advised to resort to more serious measures. During the Middle Ages, people with this feature were considered witches and witches in Europe. They were afraid of them, and often fought with disagreements. Some prejudice remained for a rather long time, in part it is present now. Thanks to her, probably, the same Bulgakov's Woland got different eyes.

Disease or feature?

Modern ophthalmology tends to believe that the color of the iris, different on the two eyes, does not affect either vigilance, or the ability to distinguish colors, and generally no negative consequences.

It is well established that heterochromia in humans can be hereditary, but it encodes its recessive gene. This means that it can manifest itself in one, two or more generations. As the research of this phenomenon continues, it is too early to say for sure about its absolute harmfulness, nor about complete safety. Doctors recommend all owners of special eyes to take responsibility for health and not forget about medical examinations.

Forms and features

Ophthalmologists distinguish two forms: full and partial (sectoral). Complete heterochromia of the eyes in humans is manifested in the form of completely different colors of the right and left irises. For example, one eye can be carim, the other - blue. By the way, this is the most common combination. With a sectoral color, the color has a part of the iris of the eye. For example, a green-eyed person has a gray speck on one of his eyes. There is another type - acquired heterochromy. It happens in those who have been injured or burn eyes. Sometimes this effect is manifested with brain damage.

Heterochromy in numbers

Specialists say that the average frequency of this phenomenon is low. Heterochromia in man is in one case of 250 thousand. According to doctors, women have different eyes more often than men. Sectoral form is quite rare, but full is observed in most "patients".

Animal world

Today, breeders of thoroughbred cats and dogs of certain breeds like this feature is the mainstream. First of all, this applies to such breeds of dogs as husky, husky, malamute. These northern handsome people can often notice ocelli, colored asymmetrically. For example, one is white-blue, the other is dark blue. Cats often surprise the hosts much more radical combinations. Heterochromia in animals is much more common than in humans.

Eyes of stars

Seeing a rather modest statistics, one might assume that the chance to see such a miracle from someone from celebrities is minimal. In fact, there are a lot of owners of multi-colored eyes among the stars. For example, the Australian actress Jane Seymour, known to the world on the TV series "Doctor Quinn."

The bright beauty Demi Moore is also perfectly visible heterochromia. The photos of the actress prove that her one eye is brown, the second is green.

Benedict Camberbatch, who played the role of Sherlock Holmes, is the owner of unusual eyes. Both his irises are gray-green, but on one there is a brown speck. A distinctive feature is also the left eye of David Bowie. Pseudoheterochromia he acquired as a result of a trauma received in a school fight. Now the left pupil of the actor can not narrow, and on the iris a spot appears that can change the color from blue to green.

There are among the stars and imitators - those who were born with the most ordinary eyes, but not indifferent to this kind of zest in appearance. For example, rocker Marilyn Manson. The image invented by this king is shocked by the contrast of the almost white left eye and the coal-black right.

Modern science at the service of the people

As seen in the last example, some are attracted by heterochromia. A person with the same eyes sometimes has a desire to bring into his appearance some zest. But many owners of unusual eyes want to get rid of it. Modern science allows to achieve both effects without any surgical interventions. To correct the hue of the iris, it is enough to put colored lenses. The choice of colors and shapes is huge. All funds available in the arsenal of ophthalmologists refer exclusively to the decorative side of the question. Any drugs designed to eradicate the cause of a different eye color are not currently applied.
