How does tears protect the body from diseases?

Tears contain an enzyme called lysozyme. This enzyme is able to destroy the cell walls of certain bacteria, thereby protecting the body from infection by these organisims.

It can also protect the body from infection by constantly flowing, flushing out the eye and preventing entry of these organisims into the body.
