In brief: Teary eyes with yawn

As you yawn, you're squeezing the lacrimal ducts in the eyes and that makes the tears back up into the eyes, hence the increased fluid in your eyes.

In brief: Natural response

I don't think anyone knows for sure.
My guess is that its natures way of moisturizing your eyes when you are fatigued. Most individuals yawn when they are tired. I just did it right now--i barely moved any of my facial features (sort of a mini yawn), but i was rewarded with a moist eye... ;-).
