#7 – Dry Eyes
Your eyes water when they're dry.
Tears have three different components - fat, mucus and water. If they aren't exactly in their right quantities, the eyes could become dry. In such a manner, your brain responds to dryness by producing more tears.

Eyes heal quickly.
It will only take approximately 24-48 hours for the eye to heal a corneal scratch.
#5 – Newborns vs Tears
Newborns don't produce tears.
Yes, they cry loudly, but they cannot produce tears. Babies tears begin to flow only when they are around 4 to 13 weeks old.
