Who gave you your first black eye

Your baby's eye color - interesting facts

All babies have blue eyes. This is what they say as is well known. So that you are not disappointed when your darling opens their eyes for the first time and they are not blue, we explain everything about baby's eye color.

The moment your baby opens its eyes for the first time is unforgettable. You should enjoy it. Whether your baby gets an eye color similar to yours or dad's depends on many factors.

The article clarifies which factors play a role in the development of the color. We also go into whether the baby's eye color is fixed or has changed immediately after birth.

You cannot determine the baby's eye color, but here you can read the probability that your baby will get an eye color.

The first glance - your baby has dark gray eyes?

The color of the baby's eyes is of great interest to parents. The birth is behind you, your baby cuddles in your arms and then it opens its eyes. What an exciting moment!

Does it have your blue eyes or your dad's brown ones? Your baby's slightly puffy eyes open very slowly, as if they have to get used to gravity first. You look your child in the eyes for the first time and you see ... gray eyes, dark gray? Something indefinable?

Possible eye colors of a baby after birth:

  • blue
  • brown
  • Gray
  • black
  • dark gray

The saying “Every baby has blue eyes” applies to a relatively small part of the world's population. In central and northern Europe, the chances are good that a baby's eyes are blue. But that doesn't mean that it will stay that way.

To come to the point: if a baby has brown eyes, nothing or not much changes in that. Babies with brown eyes only change the intensity of the color.

It looks different with blue eyes. Nothing is fixed here yet. Not all babies have blue or brown eyes when they are born. Your baby may also have dark gray, gray, or black eyes after it is born.

Often these eyes show a slight shimmer that seems to lie on the eyes like a film. These eyes will also change.

The color of the eyes of the baby at two weeks

The color of the eyes is influenced by the dye melanin. The production of melanin only begins shortly before birth. When a baby opens their eyes, they often appear blue.

The blue color is not created by a dye, but is due to the refraction of light, as is the case with water and sky. Actually, blue eyes are colorless.

The incident light is reflected by the iris after birth. The baby's eyes appear blue. You can find out how the sense of sight develops here.

When does your baby change eyes color?

If your baby is born with blue eyes, it initially shows that melanin production has not yet started and the iris of the eye is not yet absorbing light.

That was not necessary so far, because it was nice and dark in the womb. The production of melanin begins at a different point in time for each child. There are babies whose eyes don't change after two weeks.

Other babies show a color after six weeks, after two months it has changed slightly in intensity and tone. The color of the eyes is then different again after six months. We are talking about nuances here.

Because you like to look your baby in the eye, you can notice these slight changes.

After three to six months, the color of the eyes is final in most babies. Some wait until their second birthday before the color solidifies. Very rarely does the eye color change again during puberty. This is due to hormones.

A pediatrician test can give you a clue as to whether your baby's eye color will change. If the iris shimmers yellow when viewed from the side under simple light irradiation, your baby will likely get brown or green eyes.

If it continues to appear light blue, your baby will keep the color of their eyes. You can use this opportunity to have someone check whether your baby's pupils are behaving appropriately for their age and whether their eyes are okay.

Here you will find an overview of what the pediatrician checkups cover.

Who does your baby get the eye color from?

The genetic makeup of the parents determines the color of the eyes of babies. Perhaps you remember Mendel's laws in biology class? Mr. Mendel explained heredity using peas.

In order to find out whether your baby gets the eye color from you or his dad, genetics provides a direction.

There are dominant genes that are more prevalent. The recessive genes are inherited less often. Each eye color has a different dominance.

Brown eyes prevail most often, while blue and gray eyes are the least dominant. They are inherited recessively. Green eyes are in the middle.

In principle, your baby gets the eye color from a genetic mix of you and dad. There are two gene copies for this one characteristic (the color of the eyes). The scientific name is diploid.

The gene that determines the trait exists as a double set of chromosomes. The color that prevails is the phenotype. The other characteristic of the genotype. This is not pronounced, but is present in the genetic make-up.

Depending on the inheritance of a gene, the more dominant gene determines the color. For example, if you have brown eyes and your husband green, your child receives the genetic information brown + green.

Since brown is more dominant, it is likely that your baby will have brown eyes. However, you may have parents who also have brown and green eyes. The color information for green and brown is then stored in your genes.

You pass on the color information for green to your child and your baby will get green eyes.

The color of the eyes is a surprise

Several genes play a role in the formation of the baby's eye color. They influence the color intensity or the shade of color.

The more you know about your family tree, the better you can determine the likelihood of what eye color the baby will have.

The following list gives you an overview of which combination of colors is most likely to make the baby's eye color.

  • blue + blue = blue
  • green + green = green
  • brown + brown = brown
  • blue + green = green or blue
  • blue + brown = brown
  • green + brown = brown

Most predictions only use the parents' eye colors. There are certainly couples who both have brown eyes and the baby green. There is no model that can predict exactly what eye color a baby will be.

The color of the eyes

The color of the iris is determined by melanocytes, a specific cell type. The melanocytes produce melanin, a dye. This endogenous substance colors cells of the skin and eyes from dark brown to black, but also yellowish and reddish.

The higher the number of melanocytes, the darker the color. If a baby has light-colored eyes, there are (almost) no cells in the iris that make melanin.

The eyes have little or no pigment and appear blue. Green eyes have a slightly higher number of pigments, while most pigments are brown.

How the color of the eyes actually comes about is not fully understood. The melanocytes are just one of the determining factors.

The eye color shows the character

Green eyes, frog nature, no trace of love. Everyone knows these and similar sayings. Of course, the color of the eyes does not say anything about a person's character.

But like skin color, it influences the risk of disease. The level of pigmentation determines the sensitivity of the eyes to light. The coloring substance melanin reacts to the light radiation.

The brighter the eyes, the more light the eye cells absorb. In the dark north, people have lighter eyes than in the light, intense south. Melanin protects the eyes from exposure to high levels of light.

That is why babies born in southern countries are protected from strong sunlight by their dark eyes shortly after birth.

It is scientifically not clear whether light eyes contribute to a better supply of vitamin D. This connection has been established in fair-skinned people.

People with blue eyes are 70 times more likely than people with brown eyes to develop age-related macular degeneration. This disease severely affects eyesight and can lead to blindness.

There is no cure and only complex treatment methods. If your baby's eyes are light-colored, it's important that you protect them appropriately from the sun.

The most common baby eye color

Most babies in the world have brown eyes. The fact that blue eyes even exist is attributed to a mutation that spread in Europe 6,000 to 10,000 years ago.

According to this, all people with blue eyes descend from one person or a few people, as scientists in Copenhagen found out.

People with blue eyes all show the same mutation in the OCA2 gene, which prevents the pigment melanin from being stored in the iris.

Some eye color facts

  • 90 percent of all people worldwide have brown eyes.
  • Eight percent of people have blue eyes.
  • Green eyes show two percent of the world's population.
  • Very rare (one percent) is iris heterochromia, in which the eyes are two different colors.
  • A sub-form is partial heterochromia, in which, for example, a ring of the iris or spots of the iris are of a different color.

Presumably, this mutation was able to spread because humans from the Mesolithic Age (9,500 to 4,500 BC) until the 19th century reproduced within spatially narrow limits. Couples with blue eyes passed these on to their offspring.

With the wave of emigration to America, blue eyes reached the USA and Canada. Until the time of this mutation, all humans had brown eyes. In Estonia, 99 percent of people have blue eyes, in Germany around 30 percent.

Although green eyes genetically prevail over blue eyes, they are less common. A special form of green-brown eyes are so-called "Hazel" eyes.

These show different colors (brown, green, blue with golden spots or dots) in different light situations.

The refraction of light in the second layer of the iris is responsible for this. This name is unknown in Germany. People with Hazel eyes cannot decide what color their eyes are.
