There are 3 kinds of Tears. Basically when we thought of tears, the imagination is of being sad and crying. But, there is a lot more than this to know about the tears.

| Types of Tears |
3 kinds of tears in the human eye:
- Basal tears
- Reflexive tears
- Psych tears.
# 1 - Basal tears:
Basal tears are present in your eyes all the time and manufactured at a
rate of 1 to 2 micro-liter every minute. The job of basal tears is to keep the eye
lubricated, hydrated, and smooth out small dirt and dust from the cornea.
# 2 - Reflexive tears:
Reflexive tears works as a 'fighting squad' of the
eyes, responsive to pokes in the eye, onion fumes from cutting them and
more other irritants that may happen to the eye.
# 3 - Psych tears:
Psych tears are triggered at certain emotional states, produced by the lacrimal system. They are also
known to release some stress-induced chemicals in the brain that helps
us relax, which also explains why we sometimes feel better after crying.
