Can excessive crying cause eye problems?

I know muscles in your eyes are used when you cry, but can crying A LOT (such as everyday) cause physical issues?

If crying could possibly create a problem, then how much would you have to cry for the problems to occur?

Just an anecdote but it happened to my mother when my father died. She cried so much over a period of days that the sclera of her eye got bright red and swelled up past her cornea. Seeing her eyeball bleed was one of the most disgusting things I have ever seen.

I think it was Jodie Foster who said her eyes were badly bloodshot after repeatedly filming a scene where she was crying

That can really happen? Interesting! Not the blood part but, even so, very scary!

May I also ask why a human being even cries? Are we the only beings that cry due to our emotions?
And how does our body react to this emotion physically? Brain cells react to sadness?

There, there. It’ll be okay. You can stop crying now.
Here’s a popsicle.

I’m crying pretty regularly at the moment (not all the time but several times a day) my eyes hurt. They are puffy and bloodshot. No crying blood so far.

:’) thank you
