They are actually goggles that you get to mess around with in health class. Also known as drunk goggles. You put them on and they distort your vision just like if you were drunk! Its fun to play catch with them on, and a little dangerous.
Kid 1: "Did your class get to try out those beer goggles?"
Kid 2: "Hell yea. One kid tripped over a desk and cracked his head open."
