What Is Eye Color?

The color of the eyes is the color of the iris, which is the circular part of the eye that encloses the pupil. It is not formed by various colored substances, such as paint or cosmetics, because it relies on the quantity of melanin present. The more melanin the iris of your baby has, the darker the eyes will look. The smaller the amount of melanin, the lighter the eye color.

It is not only pigment that determines eye color, as genetic inheritance and the reflection of light can have a say, too. Because the appearance of the iris is also affected by light, it means that their eye color may appear different when exposed to sunlight or in the dark.

As time passes and melanin levels are fully developed, you can see your baby's actual eye color, which typically occurs during the first year. It is the process that contributes to making the change in the color of babies' eyes such an interesting milestone to be observed by parents.

How Do Eyes Get Their Color?

The basis of eye color starts before birth, yet it is not conclusive. Eye melanocytes are the pigment-producing cells that begin to form during pregnancy. These cells get more active after birth and when babies are exposed to light.

During the initial months, the melanocytes progressively produced increased melanin, which makes the iris darker. The darker the eyes, the more melanin cells will be created. That is why, as time passes by, the eyes of a baby may change to blue, hazel, green, or brown.

When Do Babies’ Eyes Change Color?

The change in eye color of babies typically begins during the first six months after birth. At 9-12 months, the eyes of many babies are already close to their final color, but fine changes may still occur until the age of 3. There are those children who develop gradually up to the age of 5 or 6 years, and after that, extremes are very uncommon.

Why Do Babies’ Eyes Change Color?

  • What Role Do Genetics Play in a Baby's Eye Color?

The extent of the pigment your baby will have in his/her eyes is influenced by genetic factors. There are several genes from each parent that are related to melanin production. That is, two brown-eyed parents may have a blue baby depending on the genetic combination.

  • What Role Does Melanin Play in a Baby’s Eye Color?

Melanin is the pigment-producer of a person’s eyes. Low levels of melanin result in a blue or gray color. The green or hazel color is caused by moderate levels. The high levels of melanin cause the brown or dark color. The final color is attained when the melanin production becomes stable.

What Color Eyes Are Babies Born With?

The majority of the babies are born with either blue or gray eyes, which is not necessarily the final color. The light complexion occurs due to the reduced melanin. Melanin production increases with the infant's exposure to light, and their eye color becomes visible.

  • Are All Babies Born with Blue Eyes?

Babies do not necessarily begin with blue eyes. However, this is a common occurrence in European infants. Individuals of Asian, African, and Hispanic origins are often born with brown or dark gray eyes because they are born with elevated levels of melanin. Thus, the color in which you were born is a matter of genetics and ethnicity, a gorgeous combination of the features of both parents.

What Color Will Baby’s Eyes Change To?

Eyes generally darkened with age: blue to green or hazel, green to brown, and/or hazel to deeper brown.

Although the majority of changes are in favor of darker colors, some babies may become a bit lighter as their melanin stabilizes. When the eyes of your baby are still light when he/she is one year old, then their eyes will probably always be so.
