Why does baby eye color change?
Just like the myth that your heart stops when you sneeze, there are plenty of myths and false facts surrounding newborn baby eyes and colors. 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. It’s another change that’s exciting to observe in your little one.
Many newborn baby eyes appear blue or gray, and whether or not this color changes frequently depends on the parents' eye colors.
The iris is the part of the eye responsible for pigmentation, and 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's 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.
