Tears and Blinking: Main natural defenses of the eyes are the tears that have antibodies, white blood cells and many other immune compounds normally circulating in the blood. The pumbing action of blinking constantly is removing minor foreign bodies and germs from the eye and into the back of the nasal cavity.

Tears: Tears contain antibodies, and there is an active flow from the tear glands across the eye to the drain of the tears (puncta). This flow helps keep the eye rinsed off, and replenishes the antibody rich tears. So tears serve many functions, including being an important barrier to infection. Additionally, the conjunctival and corneal epithelium serve as a physical barrier.
