What is that feeling when you meet someone you owe money to?
Adrenaline, right?

We have all seen the babies with big eyes and I was led to believe that the reason is due to that the eye's are already 90% of the size that they are going to be and that of course leads me to believe that human eye's grow very little from birth to adult hood.
However our resident researcher has decided that we are wrong ... do we need a second opinion?

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 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.
The only human body part that does not grow after birth is the ossicular chain, which is composed of three small bones and is located in the middle ear. These bones are also the smallest lightest bones in the human body. Each bone is smaller than a grain of rice.
