Q: My one-month old’s eyes are a dark blue-ish colour, but I’ve heard that this could change in the coming months. When will we know what colour his eyes really are?
A: Non-Caucasian infants are almost always born with dark eyes that will stay dark, while all Caucasian babies are born with blue eyes. In those babies who are born with blue eyes but are destined to be brown-eyed, brown spots usually begin appearing in the iris around three months of age. The final eye colour is usually evident by six months.
