Human eyes are always the same size from the birth

baby eyes

Our eyes remain the same in size throughout our life but our ears and nose keep gaining bits of mass as we grow older.

Human eyes grow rapidly in the womb and for the first three months after birth. By three months, our eyes are as big as they’ll ever be. The corneas have reached their full width, although inside the eyes, the front-to-back length will increase somewhat. Then our eyes move farther apart in the face as the head grows.

The dimensions differ among adults by only one or two millimeters. The vertical measure, generally less than the horizontal distance, is about 24 mm among adults, at birth about 16-17 mm.
