At one year old a baby’s eyes will have settled to be the colour they will be for life. Before this is a different story…..

You inherit your eye colour from your parent but no matter what the colour is now it may have been blue when you were born. Melanin is the brown pigment molecule that colours your eyes, hair and skin. When you are born this has not been fully deposited in the irises of your eyes. Irises containing a large amount of melanin appear black or brown. Less melanin may appear as light brown or green. If your eyes contain very small amounts of melanin they will appear blue or light grey.

Melanin production generally increases during the first year of a baby’s life which leads to a deepening of eye colour. The colour is often stable by about one year old.
