Say goodbye to tearing, stinging, irritated eyes when chopping, mincing, dicing and slicing onions and their relatives leeks, scallions and chives. Wearing these stylish and comfortable Onion Goggles will protect your eyes from irritating onion vapors. The soft foam seal keeps out the nasty vapors. When onions are cut, an enzyme called sulfoxide lyase and sulfuric compounds are released from the broken cells. When exposed to air, they react with one another to form a vapor. As this vapor evaporates, it irritates our eyes and causes us to cry. Kitchen folklore remedies such as burning candles or matches, slicing onions under water and freezing the onions before cutting are not effective. Patented design. When all the right people, and ingredients, kitchen tools, and food come together, we call this The Art of Gathering.
