Tears are made of a combination or water, oil, mucus, anti-bodies, and special proteins. Basically the oil is needed for lubrication, the water for moisture, mucus for proper spreading and anti-bodies and proteins for resistance from infection.

An imbalance in the tear-flow system is what causes dry eyes.
