Some of the functions of tears include lubricating the eyes (basal tears), removing irritants (reflex tears), and also aiding the immune system. [6] Tears also occur as a part of the body's natural pain response. [7]
Tears are the clear, salty solution that glands above your eyes produce in response to different triggers. They’re made up of water, salt and more.
Basal tears are present in the eyes at all times. They keep the eyes bathed in a salty liquid that constantly moisturizes and lubricates them. This ever-present liquid also washes dirt and dust out of the eyes, and with its antibacterial substances provides protection against infection.
