Frequently Asked Questions
Can two brown-eyed parents have a blue-eyed baby?
Yes. If both parents carry a recessive gene for blue eyes, there is approximately a 25 percent chance of having a blue-eyed child. This is more likely when grandparents have light eyes.
When does a baby eye color become permanent?
Most babies are born with lighter eyes that may darken over time. Eye color typically stabilizes between 6 and 12 months of age, though subtle changes can occur up to age 3.
