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.Eye protection technology meets kitchen practicality with these Original patented and innovative Onion Goggles. Say goodbye to tearing, stinging, and irritated eyes when chopping, mincing, dicing and slicing onions, leeks, scallions, and chives. 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 tear.No more tears! Kitchen folklore remedies such as burning candles or matches, slicing onions under water and freezing the onions before cutting are not very effective. We've solved this problem! The comfortable foam seal on our onion goggles is extremely effective at blocking out irritating vapors, and the slightly tinted and fog-free lenses add to the maximum clarity of the goggles.
