When will my baby's eyes change colour?

Yes, brown eyes are more common than blue eyes in babies. Brown eyes are dominant over blue eyes and most babies of different ethnicities are born with brown eyes. However, as a baby's melanin levels change and their eye color continues to develop, their eye color may lighten to green, hazel, or blue. The final eye color of a baby may not be determined until several months or even years after birth. Eye color is determined by the amount and type of melanin in the iris, which is a complex process that can be influenced by multiple genes.
