This pair of goggles, which promises no more tears when you chop onions, made us want to cry. The $18 glorified swim goggles have a seal foam seal to keep tear-inducing onion vapors from irritating your corneas.
Some easy alternatives that won't cost you a cent: Chill onions before peeling, or peel them under running water and then toss them into a food processor. You can also burn a candle next to the cutting board so the onion vapors are drawn to the heat source. Using a good, sharp knife also helps because it allows less of the tear-causing compounds to be released.
Plus, you won't end up looking like a space cadet. ::Art of Cooking
