According to the Chicago College of Medicine, eyes do continue to grow after birth. A newborn's eyes are about 75 percent the size they are going to be when fully grown.
The Chicago College explains that the eyes of babies are developing as well as growing larger. The optic nerve and internal eye structures are not fully formed at birth. Newborns do not respond much to visual stimulation, but they are able to track moving objects with their eyes within two months. In addition, a baby's ability to see clearly keeps increasing with age. At birth, a baby's eyesight is about 20/400, but it develops to 20/20 by 2 years.
