When Do Babies’ Eyes Change Color?

It’s always cute to see babies with colored eyes. However, did you know that babies’ eye color can change as they grow older and develop? While this is not really visible for Asian babies, since they will most likely have brown or black colored eyes all throughout their lifetime, Caucasian babies, on the other hand, are a different story.

“Eyes are the windows of the soul”, says an old saying. In this article, we’ll explain just why and when babies’ eyes change color and how it works.

So when do babies’ eyes change color?

The most likely case is from 3 to 6 months old. This is the point of their development stage in which there is enough pigment in your child’s iris, so the color will be much more noticeable.

While this change is not really noticeable for Asian babies, for Caucasian babies, it will most likely be seen, as their eye color could change from blue to green or brown, and other colors. However, once it’s changed to a very dark color, it will probably stay that way.

Genetics also play an important role when it comes to eye color changes. A baby who has, let’s say, an Asian father and a Caucasian mother, will probably have a 50/50 chance of having colored eyes versus normal, brown or black eyes.

Why do babies’ eyes change color?

The simple reason for changing eye color is the melanin processing as our babies develop. First, let’s have a little refresher course about melanin, and how it affects the eye color of humans in general.

The melanin is the pigment that’s needed by the iris to give off an eye color for any human. Here’s a rule of thumb as to how much melanin is needed to create a specific eye color:

Amount of Melanin Possible Eye color
A little amount Blue
Average amount Hazel, Green, Gray
More amount Brown, Black

Babies are still in their development stage during the first 3 months of their life as infants. Since all of their body parts and cells are still generating and growing, the melanin is one of them. From the chart above, we can see that the amount of melanin can affect the eye color of your child.

If you think your baby already has blue eyes, think again – it’s probably just because they didn’t have enough melanin in their iris just yet. You should wait for when they are about 3 to 6 months old if any change is visible.

On the other hand, babies who end up having brown or black eyes from the start are most likely going to stay that way, since their irises are already filled with enough pigment. Once your baby displays a dark color for their eyes, they will less likely have blue or green eyes.

There are pros and cons to having a lighter eye color for your baby, though. For instance, here are the advantages:

  • They will be more photogenic (may get a lot of commercial casting opportunities)
  • They’re simply cute to look at (your guests and relatives will adore them)

However, there is also a disadvantage of a little amount of melanin that makes a lighter eye color:

  • They’re more sensitive to light (little melanin means less protection)

In line with this, there has still been little evidence to the rumor that dark-colored eyes have better visual capability than those with lighter eye color.

If you become dissatisfied with your baby’s eye color, you really can’t do anything until they’ve grown up at the right age to be able to wear contact lenses. This is because wearing contacts is a big responsibility, and babies may not be that fit to wear them.

Colored contacts could help your child gain more confidence. For instance, if they grew up on a community with kids having blue or green eyes, and they’re the only one with Asian or black/brown eyes, they may benefit from having colored contacts.

However, they need to be at the age when they are responsible for their belongings so that the contacts go safely with them. For more information about color contacts, click here.

The next time you encounter a baby having a different eye color from the time they were born, don’t panic – it’s a normal thing among developing babies. This is especially the case if the baby has some Asian origins other than the Caucasian side of their parents, so their eye color could possibly change.

Eye color is an interesting thing, and it makes your baby more photogenic. However, it’s still important to know that eye color is just a color – what matters is that your baby is able to see the world clearly with no visual defects, and that’s all that should matter to have a healthy and happy child.
