   Chill your onions before using them: Throw your onions in the freezer about 15 minutes before using them. The now chilled onions will be slower to react, thus releasing less enzymes and leaving you dry-eyed as you chop them up. Take note not to freeze the onions though so they're not blocked and impossible to cut.
2. Breathe through your mouth: Onion vapours make us cry when they react with water on the surface of our eyes, also because our tear ducts are close to the olfactory glands in the nose, just breathing onion gasses through them can cause the eyes to water. Solution: Breathe through your mouth, bypassing the olfactory gland. Also stick your tongue out while your mouth is open, the idea is some of the onion gasses  will be caught by the tongue before they reach your eyes, causing it to water less.
3. Use lemon juice: Squeeze some lemon juice on your chopping board, the citric acid in the lemon will neutralize the enzyme in the onions.
4. Chop under running water: The running water will help neutralize some of the enzymes making you less prone to tears.                                                  Source:Pulse
