Onions produce an irritating sulphur gas that makes us cry, but there are a few ways to prevent this gas from bringing tears to your eyes.

Firstly, by cooling down the onions in the fridge or freezer, you slow the release of the irritating gas to slow the onset of crying.
Secondly, by removing the root of the onion you remove a majority of the harmful gas, thereby reducing its ability to make you cry.
Thirdly, try cutting the onion into quarters and letting it sit for a while, so a majority of the gas can escape into the environment, leaving the onion defenceless against your cutting.
Finally, by wearing a pair of goggles you prevent the onion gas from reaching your eyes to irritate them, leaving you tear free.
