A member asked:

What are tears made of besides water?

A doctor has provided 1 answer

Many components: Tears are basically a salt water solution containing also wetting agents (mucins), oils and a variety of proteins which can combat infection and nutrients for the cornea. They are actually quite complex and critical for the survival of the front of the eye.
