My eyes are buuurning!

I just suddenly got super emotional and started crying. My eyes instantly started burning. It felt like when you get soap in your eyes or you rub your eyes when your hands aren't clean. Like a burning/itchy feeling.

Needless to say, I had to pull myself together rather quickly. I rinsed my eyes out with some cold water and that has helped quite a bit, but they are still burning a little.

I have never had this happen before. What just happened?
