This is coming from somebody with zero medical background.
I can’t speak for why it is eyes and tears that are affected by sadness (maybe the proximity to the brain). But I assume the connection itself is neurological aided a lot by hormones. It also isn’t static, it can change over time.
I for example completely lost the ability to cry. No matter how fucked up the situation, how sad, how stressed I am I feel the pressure in my eyes but I can’t cry. Keyword being “lost”, it wasn’t always like that.
But then there are people that will literally cry at every possible occasion, not even connected to sadness in any way.
