The mystery behind how and why newborns have different eye colours has been a source of fascination for centuries. While it can be a surprise for parents to discover their baby’s eye colour at birth, it may be comforting to know that it was decided long before their little one arrived. In this article, we’ll be uncovering the mystery of newborn eye colour. We’ll explore how eye colour develops, what to expect and the factors that influence eye colour in babies. So, let’s take a closer look at the fascinating world of newborn eye colour.

What Determines Newborn Eye Colour?

When it comes to determining newborn eye colour, genetics plays a major role. Eye colour is determined by two main factors: the pigment melanin and the amount of melanin present. Melanin is the pigment that gives our skin and eyes colour. The amount of melanin in the eyes determines how dark or light the eye colour will be. The more melanin present, the darker the eye colour will be. This is why some babies have darker eyes, while others have lighter eyes.

What Eye Colours Can Newborns Have?

Since eye colour is determined by genetics and the amount of melanin present, newborns can have a wide range of eye colours. The most common eye colours for newborns are blue, green, hazel, and brown. However, babies can have other eye colours, such as gray and amber.

How Does Eye Colour Develop?

Eyes begin to develop in the womb around the 7th week of pregnancy. During this time, the baby’s eyes are making melanin, which will determine the final eye colour. By the time the baby is born, the eye colour should be set. Eye colour can change slightly during the first few years of life, but it will usually stay the same after that.

Factors that Influence Newborn Eye Colour

As we mentioned earlier, several factors can influence newborn eye colour. These include genetics, environmental factors, and the amount of melanin present.

Genetics is the most influential factor when it comes to eye colour. Eye colour is determined by the combination of genes inherited from the parents. For example, if both parents have brown eyes, the baby is more likely to have brown eyes. If one parent has blue eyes and the other has brown eyes, the baby may have a combination of the two colours, such as hazel.

Environmental factors can also influence newborn eye colour, although to a lesser extent. For example, if the mother is exposed to sunlight during pregnancy, this can cause the baby’s eyes to become darker. Similarly, the mother’s diet during pregnancy can influence the amount of melanin produced, which can affect the baby’s eye colour.

Finally, the amount of melanin present plays a role in determining newborn eye colour. The more melanin present, the darker the eye colour will be.

Is Eye Colour Fixed for Life?

Once a baby’s eye colour has been determined, it is usually fixed for life. However, eye colour can change slightly during the first few years of life. This is because the amount of melanin produced can fluctuate, which can cause the eye colour to darken or lighten slightly. After the first few years, eye colour should remain the same.
