Brown, green, blue, black … the color of a child’s eyes will not acknowledge the debate Most of them have gray eyes At the time of birth. In the first months of life, children will continue with this eye color and then change it. TheWhy does this uniformity occurIf each child has different genetics?
The scientific explanation of this event is that the cells responsible for defining the tone are still immature, they do not have to perform their function, in addition, in addition, They need to gradually replace the sunlight. We are talking about melanocytes, which are activated with sunlight until melanin produces, which gives a lighter or dark tone in their eyes.
Why are almost all children born with gray eyes?
At birth, baby melanocytes are still immature, and They are not ready to make melanin Because the little one has been dark in the womb for nine months. Therefore, there is no need to create these cells for the color of the iris.
During the first month of the baby, these melanocytes are growing to a large extent, thanks to the stimulants they receive from the sun rays. When are they completed by creation The ‘true’ color of the iris appear Of the little ones, which would be similar Child genetic information It is printed on your DNA.
At what time is the definite color of the iris in children?
Changes in the color of the children’s eyes can be maintained up to two years, when the color begins to look like a firm tone. However, it is in contrast About three years When the baby’s eye color says blue, dark brown, green or honey. From this moment, melanocytes have already matured enough to produce all melanin that color the eyes.
Of course, the baby’s eyes in a firm color, actually affecting her genetic, so this can be different in every child. However, experts point out that children born with dark -eyed, or quickly dark in the first weeks of life Keep this tone for a lifetime, Because they are rare to lose melanin.
The color part of the eye is formed by the outer area, the area of another inner and the center, which is called stroma. The amount of melanin and protein we have in the Carnival Stroma Determine the firm color. For example, brown eyes accumulate a large amount of melanin in the front of the iris, which makes the impact of light directly.
