Onion-chopping goggles

Scott Beale of Laughing Squid spotted these handsome goggles designed to protect your eyes when cutting onions. One reviewer on Amazon reports that they're useful for, er, other purposes too:
 Images I 31Zttmyd0Hl. Aa250 I bought these to watch TV. My ceiling fan dries my eyes out really badly and with summer coming, I was looking for a solution. I found these and thought that if they keep onion gas out, they should keep the fan air away. They work well for this and I could see how they would be great for the intended purpose.
