Water comes to your eyes to clean your eyeballs and moisten your nasal passages.
If you cry or laugh, you may breathe hard enough to dry out your nasal passages, which in turn causes water to come from your eyes to moisten them.
The brain can also get into the habit of watering your eyes in certain situation.
Notice I didn't use the word you didn't use for this phenomenon.
