What do tears do to Your Eyes?

Summary. You may only think of tears as those salty drops that fall from your eyes when you cry. Actually, your tears clean your eyes every time you blink.

What are tears made of?

Tears are a clear liquid secreted by the lacrimal glands (tear gland) found in the eyes of all land mammals.
