Eyes are considered a mirror in which the human soul is reflected. The color of this mirror is different for all people: brown, blue, gray, green. Rarely there are various unique shades. So, you can see people with almost black eyes. But the most amazing and rare eye color is purple. Seeing such eyes in the photo, people cannot believe that there was no "Photoshop". However, there are indeed violet-colored eyes. It is believed to be a mutation. Purple eyes are definitely a very rare occurrence. There are several hypotheses for the appearance of this eye color.

In biology, it has long been established that the color of the iris directly depends on the degree of distribution, type, and amount of pigment. The fibers of the iris and vessels also affect its shade. The interaction of only 6 genes determines what color the eyes will be. Most often, dark tones take precedence over light ones, and a child who has one parent with brown eyes is most likely(in about 60% of cases) will inherit this particular color. How can purple eyes appear with all this? There are various explanations for this kind of genetic mutation.

The myth of the emergence of Alexandria

An ancient legend tells that a very long time ago in Egypt, in a small village, the sky lit up with a bright flash. Why it arose, it was not possible to find out. But since then, in this settlement, women began to give birth to children with violet eyes. So Alexandria appeared - an unusually beautiful girl who gave the name to this phenomenon. She was the first to show this mutation - purple eyes. Of course, this is just a beautiful fairy tale. But the phenomenon itself exists. An example is the brilliant Elizabeth Taylor. She was born with the most beautiful eyelashes, and they were very thick, because … they grew in two rows. This anomaly is called distichiasis. She made the actress look charming and attractive. But it was not only such a rare phenomenon that was unique in it, but also another mutation - purple eyes. Taking a closer look at the photos of Elizabeth Taylor, you can see that her eyes have a violet tint.

Marquezani syndrome as the cause of violet eyes

Science has its own version of the origin of this mutation. Purple eyes can be found in people suffering from Marchesani syndrome. Patients are characterized by short stature, a certain underdevelopment of the arms and legs, as well as poor eyesight. Directly on the purple hue of the iris is not indicated, but it is known that vision problems can (albeit in rare cases)provoke a change in their color.

Albinos with violet eyes

There is also a third reason that can cause the appearance of such a unique shade of the iris - a gene mutation. Purple eyes, according to this version, belong to albino people, in whose bodies there is no melanin, which is responsible for the tones of hair, skin, and also the iris. Their eyes look red, but they are also blue, and sometimes with a purple tint.

However, it is not so important who gave the world such a unique phenomenon: supernatural powers or changes in genetics. Be that as it may, the lilac shade of the eyes always seems unusual, attractive. It attracts attention and causes interest in their owner.
