The person's eyes are the mirror of his soul. By the color of the eyes, you can determine the nature and psychological characteristics of a person. However, there are people whose eye color is different. Different eyes - a phenomenon noted in 1% of the world's population. This phenomenon in medicine is called heterochromia. It manifests itself in that one eye is partially or completely different from the other in color. This phenomenon is caused by a lower content of melanin pigment in it than in the other eye. It is melanin that stains the iris of the human eye. If a person has different eyes, in the iris of a lighter one, the content of the melanin pigment decreases significantly. As a consequence, it becomes lighter than the other.
If a person has different eyes, this featureis often congenital. However, heterochromia can occur in a person during life. In this case, you should consult a doctor, because this may be a consequence of various diseases. First, the reason that a person has different eyes is a lack or excess of the melanin pigment. This may indicate the presence of the following diseases: glaucoma, inflammatory processes of the iris caused by rheumatism, influenza or tuberculosis, as well as the development of a benign tumor in the human body. In addition, different eyes can appear as a person's reaction to drugs and medicines.
Another reason for heterochromism is the untimely removal of an iron or copper splinter in an eye injury. In this case, the iris can change its color.
Heterochromia has two varieties. It can be complete and partial. Partial heterochromy is manifested in the fact that the human eye is immediately colored in two colors, that is, one part of the iris will have one hue, and the other will be painted in a completely different color. Complete heterochromia of the human eye - these are two eyes of different colors, different from each other.
