Baby Eyes Changing Color: The Surprising Truth
There are plenty of myths and false facts surrounding newborn baby eyes and colors.
It is important to note that most baby eye changes occur between 6 to 9 months. These changes may continue until the age of 3 since your child’s body develops and as they grow. And surprisingly, eye color may continue to change into adulthood for up to 10% of the population.
The melanin is the pigment that gives way to baby eye color, hair color, and skin color. It’s the amount of melanin that truly determines what the color your newborn baby’s eyes will be – and it is mainly genetics that determines how much melanin a person ends up with. The more melanin you have, the darker your eye color will be. The less melanin you have, the lighter your eyes will be. And melanin is activated by light exposure, which explains why over the first year of a baby’s life you may see significant eye color changes.
With that said, a baby born with already genetically high melanin levels, such as those with darker skin, may already have darker eyes at birth. In these cases, the eyes frequently stay relatively dark.
As your baby is exposed to light outside the womb and during their first year of life, their body produces melanin. This is where you’ll see your baby eyes change color. Ultimately, how much they change is determined by genetics.
