We are mostly surrounded by people with the usual eye color for us: gray, brown, blue, blue. To create a certain shade of eyes or just to emphasize their individuality, individuals use lenses of different colors. But some do not need to do this at all, since their eyes naturally have a rare color. Usually purple. This phenomenon is called the “origin of Alexandria.”
Genetic mutation
Some babies experience a change 6-10 months after birth that causes their eyes to turn a rare purple hue. This does not affect a person’s vision in any way, but there is an opinion that people with purple eyes have a tendency to cardiovascular diseases.
The mutation process takes a long time and continues until puberty. At this time the eyesbecome a darker shade, which can even be mixed with blue. It remains only to figure out how the "origin of Alexandria" is connected with genetic shifts.
There are many rare diseases in the world that accompany a person all his life and have a genetic origin. The corresponding gene code is responsible for eye color, which also determines the shade of hair and the presence of freckles. The Origin of Alexandria is one such rare anomaly.
Weil-Marquezani Syndrome
Sometimes this disease, which is hereditary, is called Weil-Marquezani syndrome. This pathology is also manifested by the following characteristic symptoms: short stature, a defect in the shape of the head and a change in the shape of the lens of the eye.
But the main feature of the Alexandria origin mutation is purple eyes. In addition, people susceptible to this genetic disease have highly developed muscles, thick fingers and a considerable layer of subcutaneous tissue. Many patients have almost no body hair, and women do not have a menstrual cycle, but they are still quite fertile.
Albinos
It is generally accepted that albinos lack melanin in the iris, and therefore their eyes are red. But sometimes it can combine with blue, and the result is a purple hue. Such cases are extremely rare and have nothing to do with the Alexandria origin mutation.
Interestingdetails
There are very few owners of violet eyes on earth. Therefore, when in 1329 a child was born with an unusual color of the iris, his parents turned to the priest for help, deciding that these were the machinations of Satan. But the church minister assured them that their child was not from the devil, but simply belongs to a special caste of people with rare violet eyes. The famous American actress Elizabeth Taylor had extraordinary violet-blue eyes that captivated her compatriots.
It is believed that the pathology is transmitted through the mother and can be aggravated from generation to generation. People with the genetic mutation "origin of Alexandria" were credited with a long life expectancy (up to 150 years), strong immunity and the inability to sunbathe in the sun.
Green eye color is also quite rare, only 2% of the world's population can boast of it. Pure black eyes and red eyes, which are found in albinos, can be classified as rare.
