❓ why
Why do some babies have blue eyes that later change color?
Quick Answer
Baby eyes can look blue because they have little melanin at birth. As pigment develops in the iris during the first months or years, the eye color may become greener, hazel, or brown.
The Full Story
Many babies, especially of European ancestry, are born with light-colored eyes because the iris has not yet built up much melanin. After birth, melanocytes in the iris can continue producing pigment, and the amount can increase over the first year or two. This gradual change can shift eye color from blue to hazel or brown. The final eye color depends on multiple genes and how much melanin is ultimately deposited in the iris.
