It is undeniable that factors such as genetics directly influence what color a child's eyes will be.
And, considering that children go through changes in eye color from birth, the reflection remains: Is it possible to predict what your child's final eye color will be?
Precisely to clarify this doubt and to address the specificities of each color of the baby eyes, that we prepared this article.
Baby's eye color before and after
A baby eye color refers to the appearance of the iris, which is the muscular ring that surrounds the pupil (the black part) of each eye.
The iris helps control the amount of light that enters the eye. The color of the iris can vary from a very light blue to a very dark brown.
The baby's pupils will always be black and the sclera (the whites) of the eyes will almost always be white. Why almost always?
Because if the child has jaundice, the color may be yellowish and, if the eyes are inflamed, the color may be pink or red.
For you to better understand this dynamic, at birth and being exposed to the strong lights of the delivery room, a process of melanin production begins in the iris due to exposure to lights. What can lead to changes in the color of the baby's eyes.
Just a little melanin and your baby will have blue eyes; add a little more and you get green, gray or hazelnut; even more and a newborn's eyes will be brown or even black.
That is, the melanin produced by the cells is the pigment responsible for giving the skin and hair color (or at least the color you had as a child) and also the eyes.
Just as sunlight makes skin a shade darker, it does the same to eye color through the iris.
What color is a baby's eyes at birth?
A baby's eye color is entirely dependent on melanin, a protein secreted by special cells called melanocytes, which also give color to a child's skin.
Babies whose heritage is dark-skinned are usually born with brown eyes, while Caucasian newborns tend to be born with blue or gray eyes.
As melanocytes respond to light, at birth a baby may have gray or blue eyes mainly due to a lack of pigment. Besides, he'd been in a dark womb up until that point.
As he is exposed to more light, over time (up to several years) the baby's eye color may change.
Brown eyes, which are the most common, are the result of very active melanocytes secreting too much melanin. Some colors tend to change over time. But, brown eyes tend to remain brown throughout life.

When does a baby's eye color stop changing?
As melanocytes take about a year to complete their work and for the baby's eye color to finally show.
It is a risk to say for sure what the child's final eye color is before the first year. However, two factors must be taken into account:
- The rate of color change may decrease after 6 months of age. The color can still change after this time, but at a slower rate;
- Sometimes the color change can continue for several years before it becomes permanent.
But is it possible, somehow, to predict the color of the baby's eyes? Find out below!
What color will your baby's eyes be?
Eye color is determined by genetics. A specific chromosome is largely responsible for determining eye color. It carries two genes, one that determines the amount of melanin in the iris and the other that controls the activity of melanocytes.
These genes work together in determining eye color. Some other genes play minor roles.
You can't necessarily predict your baby's eye color just by looking at your own eye color and your partner's eye color. But, sometimes your prediction can come true.
It's all a game of genetics. Considering this, is it possible to be sure what your baby's eye color will be? Look!
Is it possible to predict a baby's eye color?
In fact, it is not possible to predict what the baby's eye color will be. However, there are some predictions, such as:
- Two brown-eyed parents are likely to have a brown-eyed child. But they can have a child with blue, green or brown eyes, depending on the gene combination of each parent;
- Already, two parents with blue or green eyes are likely to have a child with blue eyes, or green eyes (or a blue-green combination). But, it is possible that they have a child with brown or hazel eyes;
- If one parent has darker eyes and the other parent has lighter eyes, they are a little more likely to have a child with dark eyes.
However, although there is no way to predict a baby's eye color, there is a table with some probabilities to know what the child's eye color will be.
That way you can make more detailed approximations to know what your child's eye color will be.

Your baby's genetics
The two genes best known for eye color development come in two forms, or two alleles: one that has brown and blue versions, and one that has blue and green versions.
A baby's eye color will depend on the combination of alleles it inherits from its parents. However, other eye colors such as gray, hazel, violet and various other combinations are not fully understood at this time.
To better understand, alleles are the alternative forms of a specific gene. They occupy the same gene position on homologous chromosomes, that is, on chromosomes that have genes for the same trait.
for years, brown eye color was considered the “dominant” trait and blue eye color was considered the “recessive” trait. However, modern science is beginning to show that determining eye color is not so simple.
Eye color is not influenced by one or two genes, but is instead determined by several genes working together. For this reason, it is not uncommon for children to have completely different eye colors than their parents.
So while it's rare for two blue-eyed parents to have a brown-eyed child, it's not unheard of.
This phenomenon occurs because eye color is polygenic or is influenced by several genes that work together to determine eye hue.
Many want blue-eyed children, but having brown eyes also has its positive side. Keep reading to find out more!
The strength of brown eyes
Not only the eyes of babies, but also of adults, are sensitive by nature. That's why it's important to always be on the lookout for any unusual signal.
However, despite the eyes being a sensitive region, brown eyes tend to be a little stronger than blue eyes, for example.
According to doctors, people with blue eyes, gray or green tend to be more sensitive to light than people with brown or black eyes.
People with lighter eyes often suffer from photophobia, or sensitivity to light, which causes them to rub their eyes in sunlight or feel tired after being under fluorescent lights for a while.
This sensitivity is caused by the fact that people with light eyes have less pigmentation in various layers of the eye than people with darker eyes.
As a result, they are less able to block the effects of bright lights or sunlight. Therefore, it is important for parents to keep an eye on their children when they are away from home.
Obviously, regardless of the color of your baby's eyes, it's a good idea to protect them with sunglasses outdoors. look for kids size sunglasses that offer UV protection.
After all, it is essential to take care of children's eye health and thus prevent future problems, isn't it?
