Humans have 3 types of tears that are different in their chemical composition and appear in different situations.

1. Basal tears are constantly discharged tears that keep our eyes wet.

2. Reflex tears appear because of irritation. For example, when you cut onions or when smoke gets in your face.

3. Emotional tears appear when your team wins an important match or when you break up with your beloved. Even though it looks like the same type of tears, they all look different under a microscope.
