What are the function of tears in eyes?

Answer 1

Well, tears don't really "protect" the body, as in like skin and bones protect internal organs. Tears are water with filth that has gotten into you're eyes. So if you got dust, pollen in you're eye(s), you can cry a little or create tears and the dirt and filth will come out with the tear. Usually using eye drops help, or you could lift you're upper eye lid over and tear tears will form.

Answer 2

Tears protect your eyes because whenever you cry, the tears fall out and dirt, dust and other particles in the air that get into your eye are all flushed out.

Same thing with blinking, but crying is the same thing.

Answer 3

Basically; Tears are produced by the lacrimal (tear) glands. These are situated above each eyeball. The glands continually create and release a small amount of salty fluid that is speard over the surface of our eyes when we blink or when we have something in the eye. A classic example of this is when we see someone cut an onion - The acid in the onion causes the glands to react to clear away any that hits the eye causing it to burn. The fluid then drains into the nose.

Answer 4

Tears help to moisten the eye when it becomes dry/foreign matter in the eye/irritation or when in emotional state there is rush of blood in the eyes with rise of certain biochemicals in blood..

Tears are the result of the process of crying to clean the eyes
