Brown, green, blue, black … the color of the eyes of a child at birth does not admit the discussion since then The vast majority of them has gray eyes At the time of birth. During the first months of life, children will continue with this color of the eyes, to change it later. IsBecause this uniformity occursIf each child has a different genetics?
The scientific explanation of this phenomenon is that the cells that will be responsible for defining the tone are still immature, do not perform their function as they should and, moreover, They must progressively adapt to sunlight. We are talking about melanocytes, which will be activated with sunlight until it produces melanin, which will give them a clearer or darker tone in their eyes.
Why were almost all children born with gray eyes?
At the time of birth, children’s melanocytes are still extremely immature and They are not prepared to produce melanin Since the baby was dark in the uterus for nine months. Therefore, it did not have the need to develop these cells responsible for the color of the iris.
Gradually, with the course of the first months of the child’s life, these melanocytes are developing, to a large extent, thanks to the stimuli they receive from the sun’s rays. When they have finished forming it is when The “real” iris color appears of the Piccolo, which will correspond to the Genetic information that the child Has printed on your DNA.
What time is the definitive color of the iris in children?
The changes in the color of the children’s eyes can be maintained up to two years, when the color begins to seem more similar to the definitive tone. However, it is rather About three years When it can be said that the color of the child’s eyes is blue, dark brown, green or honey. From this moment, the melanocytes have already matured enough to produce all the melanin that gives color to the eye.
Of course, in the final color the eyes of the child, what really influences his genetics, therefore will be different in all children. Even so, experts point out that children born with dark eyes or quickly obscure in the first weeks of life Keep this tone throughout your life, Since it is rare that they lose melanin.
The iris, the colored part of the eye, is made up of an outdoor area, another interior and the area of the center, which is called Stroma. The amount of melanin and protein we have in the corneal stroma is the one that Determine the final color. The brown eyes, for example, concentrate a large amount of melanin on the front of the iris, which makes the impact of light directly.
