The eye is a complex structure that capture light and movement from the surrounding world and sends this information to the brain to be interpreted.

The front of the eye (what we see when we look at others) protects the eye and focuses light on the nerve cells that line the back of the eyeball. These nerve cells, are collectively called the retina, and their communications with the brain are the primary focus of research at the Donald K Johnson Eye Institute.
