Tears are...

M         : What was the tears made from?

F          : I think our cells inside our eyes will process the tears,,

               Tears down when we get hurt, happy, sick, or another feeling..

Tears also usefull to clean up our eyes when the eyes dirty because of dust or something..

That’s my opinion, for the details tears process you can search on google but remember that this is the almighty Allah SWT. Let’s say Subhanallah.

M         :  Correct! As ingredients, tears are made of 1% water and the rest 99% 
               are feelings.
