What Really Happens?
- The Lacrimal Glands above your eyes produce the tears.
- Tears mainly consist of salt, proteins, and anti-bacterial enzymes.
- The Lacrimal Puncta (small tubular structures) drains your old tears.
- When a lot of emotional / reflex tears are created, they overwhelm the lacrimal drainage system. That’s when the tears spill out of your eyes, run down your cheeks, and sometimes dribble out of your nose.
