A little extra information..
on eye protection
"Eyes sit in sockets within the bones of your skull (known as the orbits), and are surrounded by fat, fibrous tissue and muscles that help protect them from damage. Your eyes are also protected by your eyelids and eyelashes, which block out bright light and help to keep out dust, dirt and other foreign objects.
Tears are produced by the lacrimal gland, located in the orbit just above the outside corner of each eye. Tears are swept across the front of your eyes each time you blink, and drain into ducts at the inner corners of the eyes. Tears not only lubricate the eyes, but also work with your eyelids and eyelashes to protect against dirt and infection."
