Question

What is tear made up of ?
mele tears bilkul bhi precious noi h :'(​

Answer 1

Our tears are made up of three components: lipid (oil), water and mucus. Each of these layers serves their own purpose. The oily layer is the outside of the tear film. It smooths the tear surface and keeps your tears from drying up too quickly.

Answer 2

Tears are secreted from the lacrimal glands located at the back of the top eyelid. All tears contain water, lipids, lysozyme, lipocalin, glucose, and sodium. This protein-rich, antibacterial liquid goes from the outer edge of the eyeball toward the cornea and lubricates the entire eye surface every time we blink.01-Oct-2018
