We all know about slicing onions through the pain. The burning sensation. Constantly wiping away the uncontrollable tears streaming down your cheeks with your arm. Squinting and continuing to slice with one eye barely open, hoping to get the job done as quickly as possible so you can run to the sink and rinse the burn out of your eyes.
Well, I can't scientifically prove if they actually help but when I need to cut a lot of onions, I pull out my shop goggles. I look ridiculous but I think the sulfuric gas that's created and released by the onion being cut doesn't get in my eyes. Take that, Mr. Burny Onionman!
