Why do onions make us cry when we cut them, but not when we eat them?

Question

I was helping my mom in the kitchen today, and when I started chopping onions, my eyes started stinging and tearing up. But then I realized something weird – when we eat onions in our food, they don’t make us cry at all!Can someone explain why onions make us cry when we cut them

Basically when you cut the onion it sprays little onion juices in the air and THATS what makes your eyes sting. If it’s in your mouth all the onion juices stay there, unless you took a bite out of it like an apple or something. But yeah, it’s the onion mist that burns lmao
