Does this happen to you when you yawn?

I’m not sure what the exact reason is for yawning, but when tired and trying to go to sleep & you yawn, do your eyes water up?

I was thinking of this last night as I was laying in bed and yawning every 5 seconds and water / tears were just flowing. I found it kind of annoying. What purpose does this reaction serve? It doesn’t help in the trying to fall asleep process for me. Does this happen to you? & does anyone know why or what reason this happens for?
