Why do we cry? It can be from getting hurt physically, getting dust in your eyes, or seeing a sad scene in a movie – but not all tears contain the same ingredient composition.
Humans make different types of tears:
- Emotional/Psychic Tears: Theses are tears of sadness
- Reflex Tears: We make these tears to flush our eyes in response to irritants
- Basal Tears: These are tears that we make to protect and lubricate our eyes throughout the day
All three types of tears contain salt, proteins, and antibacterial enzymes but the percentage of each differ between the types of tears. Learn more about it in the video below!
