What can change the color of the eyes during life? Was green, became a caret-blue.
In most cases, changing the color of the eyes does not mean anything bad and is considered as a curious observation.
There are two primary eye colors – conditionally blue (blue, gray, blue) and conditionally brown (brown, green). The first are recessive, the second are dominant. That is, from conditionally blue with the passage of life, conditionally brown (and vice versa) cannot turn out. And within the limits of one’s own color, people usually brighten their eyes throughout life, some faster, others slower. In very few, the color of the iris (within the color) may vary depending on the mood, lighting, interlocutor.
Eye color depends on the pigment of the iris, which is called melanin. The amount of melanin determines the color of the eyes. A large amount of this pigment creates dark eyes (black, brown and light brown), and a smaller amount forms light (green or blue).
In albino people, red (pinkish) eyes are due to the lack of melanin in the iris. Since it is transparent, through it visible blood vessels of the eye.
All people are born light-eyed, and the final eye color is formed in a child by 2-3 years, when the enzyme melanin appears.
Eye color becomes darker as a child grows up. Think of blue-eyed newborns whose eyes turn gray, green and even brown with age. Darkening of the eye is associated with melanin accumulation.
The amount of melanin is determined by heredity. There are many more dark-eyed people in the world than people with bright eyes, and the reason for this lies in the genetic dominance of symptoms associated with a large amount of melanin. Therefore, if one parent has dark eyes in a family, and the other has light eyes, their children will most likely have dark eyes.
People with light (blue, gray, green) irises are subject to the greatest fluctuations in eye color. As you know, we see reflected light, and the color of objects in the world around us is determined not only by their internal properties, but also by their surroundings. Therefore, if you closely monitor the color of the eyes, you can find that the color of the eyes changes depending on the color of clothes, cosmetics, and environment.
Some people observe that the color of their eyes changes if they get sick or are in a stressful situation. How this happens is not known for certain, but some clinical observations suggest some possible mechanisms.
There is also Horner’s syndrome – paresis of sympathetic innervation on the face. The eye color of patients with Horner’s syndrome becomes lighter. This means that the color of the eyes is also under the control of the nervous system. In addition, the clinic has some rare inflammatory diseases of the eye – Fuchs syndrome, Posner-Schlossman syndrome – in which the iris acquires a greenish tint. Often these diseases affect one eye, which leads to heterochromia – a difference in the color of the eyes of one person. There are also congenital cases of heterochromia.
If the process of color change is long and gradual and affects both eyes, then you should not be afraid.
If the eyes have significantly changed color in a short period of time, you should go to the doctor to make sure that you are doing well with the eyes.
The study suggests that the color of your eyes indicates some characteristics of your personality.
People with light blue eyes show patience and perseverance, and people with dark hazel color, despite their inherent impulsiveness, better cope with periods of crisis.
People with blue, green or gray eyes are much more likely to develop skin cancer.
It is also known that the color of the eyes imposes a certain imprint on the impression of the person as a whole. No wonder that such expressions as cold eyes or, on the contrary, warm appeared. But the reason why a person is born into the world with eyes of a particular color, scientists, it turns out, opened literally the other day.
