You may love onions, cutting them is probably a completely different story. You've really got to be a pro at slicing and dicing them without getting frustrated and shading tears.

Why do you Cry while Cutting Onions?

SIMPLE, THE GAS! THE REAL ENEMY IS THE GAS, NOT EVEN THE ONIONS

Onions grow and get their delicious flavor from sulfur, and hidden in each onion's core is a bulb containing that sulfur-based gas. When released into the air, the gas makes contact with the water in our eyes, creating sulfuric acid—right in our faces.

when you slice into an onion into its core, cutting perfectly in thin Rounds, you're sending a flood of awful gas from the sulfur-based areas directly into your eyes.

Now that you know that the inner gas-filled bulb is the cause of all your tears, how do YOU PREVENT CRYING (WATERY EYES) WHILE CUTTING ONIONS
The Answer is SIMPLE :
Before peeling the onion, take a paring knife and cut a circle around both the onion's root end and its gaseous inner bulb.


After cutting is completely round, pull the top of the onion out as one piece, this will keep the Gas intact, so the Gas won't be released.
You should see the entire length of its inner bulb, or center, attached as you pull the top off.
Dispose that Top properly. The rest part beneath is what you can do use for your cooking or any other purpose.

There's also A special Tool for Perfectly cutting the Top off an Onion to prevent that gas.
see it Below.

Dispose ke? That's even the best part of the onion

Fine, but the gas improves our eyes health-wise.
