What is the color of my fetus’ eyes? Baby Eye Color Calculator
We often find a pregnant woman wondering about the color of the eyes of the fetus, how is it determined ? especially if the color of the eyes of one of the parents is different from the color of the eyes of the other. Can the color of the fetus’s eyes be predicted while it is in the womb of its mother? And when will the color of the eyes of the fetus prove to be permanent?
❏ Eye colors
Scientifically, there are two types of eyes:
★ Colorful eyes include black, brown, hazel, and green.
★ The eyes are non-colored and include only the blue color.
❏ How do I know the color of my fetus’s eyes?
Scientifically, it is not possible to know the color of the eyes of the fetus while it is inside its mother’s womb. Still, there are other methods by which the color of the eyes of the fetus can be predicted in the future, as follows:
- The genetics between the father and the mother is calculated. If the couple’s eyes are brown or black, the fetus by more than 75% will have brown or black eyes.
- But if the eyes of one of the spouses are blue or green, and the eyes of the other are brown, then the color of the newborn’s eyes is usually brown or light.
- Despite the extent of these possibilities, the fetus may be born with an eye color that differs from all expectations or predictions due to the mother of genetics, a science-rich in surprises.
❏ Factors that determine a child’s eye color
Several factors determine the color of a newborn’s eyes, and they are as follows:
Humans have two copies of every gene. One inherits from the mother and the other from the father.
Homozygous means that two copies are identical or dominant (denoted by two capital letters such as BB). Heterozygous means that two copies of the gene differ or bend (denoted by two lowercase letters, bb).
2. The predominant eye color
Brown and green are predominant eye colors, so there is a 75 to 95% chance that a child’s eyes will become brown or green if both parents have the same color.
3. Recessive eye color
Blue is the color of the recessive eye. This means that it is very unlikely that a child will have blue eyes if both parents have brown eyes.
4. Racial or genetic factor
The genotype is the genetic makeup of a specific trait, which in this case is the color of the eyes. The genetic makeup of the mother and father determines the color of the eyes of the children.
The phenotype is the physical manifestation of the genotype, which in this case is the color of the eyes.
❏ Beliefs and facts about the color of a baby’s eyes
- Some recent studies conducted to find out the factors that control the color of the eyes of the fetus indicate that eight genetic genes control eye color, not one gene, so it is possible that if the eyes of the child are blue even though his parents have brown eyes.
- Most people think that the color of a newborn’s eyes can change with changing the color of clothes or changing the color of lighting.
- Some mothers believe that the squint that affects newborns in the first period of their lives can affect the color of their eyes and lead to their whiteness, and there is no doubt that this belief is completely wrong.
- Most babies have blue or gray eyes at the time of birth, but this color often changes during the first months after birth, and eye color can change again when the child is first six years old.
- Some mothers also believe that the presence of tears in the eyes of the newborn is a factor in fixing the color of the eyes of the fetus, and it is also evidence of the strength of the child’s vision in the future, and this is also a misconception, as the presence of tears in the eyes of the newborn is a medical condition known as obstruction of the tear duct, and often It goes away spontaneously during the first four months of a child’s life without medical intervention.
- Some people also believe that children who have black eyes have more visual acuity than children with green or blue eyes, and this is also a completely wrong belief because the color of the eyes has nothing to do with the strength of vision, and children in the first months of their life cannot Stare at the things around them.
❏ Change in your child’s eye color
The amount of melanin in the iris (the colored part of the eye) – is responsible for the change in the color of the child’s eyes, which in turn is determined by the genes that your child inherited from each parent, in addition to other factors.
❏ The role melanin plays in a child’s eye color
Melanin, produced by cells, is the pigment responsible for giving you the color of your skin and hair. Just as sunlight turns the skin into a darker color, it does the same thing to color the eyes with the iris. When your baby is born and is exposed to bright lights in the delivery room, that light begins to produce melanin in the iris, which may cause the eyes to change color.
❏ The role genetics plays in a child’s eye color (eye color genetics)
It is difficult to make hard and fast predictions about your baby’s eye color. But there are some possibilities: If both parents have brown eyes, but one of them has a parent with blue eyes, there is a small chance that babies’ eyes are blue.
If one parent has blue eyes and the other is brown, then your child’s eyes have a 50-50 percent chance of switching shades.
❏ When does your child’s eye color change?
The most dramatic eye color changes are likely to occur when your baby is between 3 and 6 months old. By this stage, the iris is storing enough pigment so it can better predict what the final pigment will be.
You may continue to notice subtle changes in eye color (green eyes slowly turn brown until your child is 3 years old. It is worth noting that dark eyes tend to remain dark for most children.)
Over time, if the melanocytes secrete little melanin, your baby will have blue eyes. If he spewed a little more, his eyes would look green or hazel. Whereas when melanocytes get too much, the eyes appear brown (the most common color of the eye).
If your child has one brown eye and one blue eye, you should bring it to the doctor’s attention; He probably has a rare genetic condition called Waardenburg syndrome.
❏ The color of the eyes of the newborn
- Often, a child is born with a color other than the original color of their eyes, so we often find most children when they are born having gray eyes, and some mothers may be happy with that, but the color of the child’s eyes changes soon after several months of birth.
- Usually, the child’s eyes change color during the first year of his life, especially that white-skinned children usually change their eyes color between gray and black in the immediate postpartum period.
- After the child completes the age of six months, the color of his eyes begins to steady to a permanent color. Usually, children with brown skin color change their eyes from gray to brown or black, and this, of course, is something that varies between children.
❏ Reasons for changing the color of the eyes of a newborn baby
The color of the eyes of a child born in the period between the sixth month to the ninth month of pregnancy changes. Because the main factor that determines the color of the child’s eyes is the conflict between the strong or dominant genes and the weak genes in the body of the newborn so that the strongest triumph are excreted.
The pupil of the eye or the black ring in the middle or center of the eye is responsible for the passage of light through it until it reaches the retina, which in turn converts the light rays of nerve signals that reach the brain to be analyzed.
And since the pupil of the eye usually appears in black, this is due to the rays of the eye that enter the eyes and are absorbed inside the eye through the tissues, and are absorbed after their reflection, then spread inside the eye and not leave it as a result of the narrowing of the pupil.
The presence of an aura surrounding the pupil of the eye determines the color of the eyes, which is known as iris color, as it is a muscle that can be stretched or contracted, as a result of the effect of the eye by light, as it grows in the dark, and reduces in light.
Then the power of the light used is reduced until the pigment of the eye color is distributed through it, through which the permanent and final color of the child’s eyes is determined after he completes the ninth month of his life.
❏ How to use a baby eye calculator?

★ What is a baby eye color calculator?
It is an electronic calculator that determines the color of the child’s eyes based on the color of the eyes of both parents.
★ How accurate is the baby eye color calculator?
This calculator is not one hundred percent accurate; Because genes do their job in this regard.
★ What is Waardenburg syndrome?
It is a syndrome in which children are born with one of their eyes brown and the other blue due to a genetic defect. This is also called ophthalmic contrast disease.
