Cut the onion in the sink under a slow steady stream of water. It helps keep the irritating compounds from reaching your eyes. If you’re super-sensitive, submerge the onion completely under water, in a shallow casserole dish.

Crazy thing that helps, but it's a scientific assist: when your eyes start to well, open your freezer and stick your face in. It works every time. It's like crazy kitchen voodoo.

One more trick I don't think anyone else put yet: start cutting from the stem end; leave the root end intact for as much of the cutting process as possible. This trick probably won't be enough for someone as sensitive to onion chemicals as you, but might be helpful as part of a multi-pronged strategy.

Pool or lab goggles. You'll look dumb but if it works it works.

Your knife isn't sharp enough. The eye burning comes from a chemical defense to attack. If you properly slice ( and not crush) you won't activate the defense. Also, you can try soaking the peeled onion in ice water first. Did this at a sandwich shop where we used the deli slicer for literally 100 onions. Eyes never watered

There's a number of things said to help. #1: Get a sharp knife. #2 Try an open bowl of vinegar by your side... it supposedly helps counteract the compounds before they can reach your eyes. Also try a burning flame next to you (obviously be safe with this) if you have a gas stove that'd probably work. #3 and the best by far - wear contacts. I used to be immune to onion cries until I got Lasik surgery and then it all went downhill lol

Goggles

Have you ever tried it with one of the sweeter varieties, like Vidalia or Maui? I don't usually get the onion tears, so I don't know if that could make a difference. Also, I know some people actually use safety goggles.

The only trick that works for me is cutting with your tongue out a bit and breathing through your mouth. You pull in all the fumes and they stick to your tongue - you can taste it happening! I was skeptical but it works

Rub fresh lemon on the blade; wouldnt hurt to spread some lemon juice on the cutting board. Will have to refresh every so often on both but i have heard this works

Wear swimming goggles

Try putting them in the fridge or freezer before slicing, the cold prevents the juices from aerosolizing

Me too! And I've tried everything but i have too sensitive eyes! Sometimes i can't open my eyes for several minutes after I've cut one! The only thing that kinda works is to put the peeled onion in the fridge for couple hours!

Have you tried to place a wet paper towel next to the cutting board? It really works

If you have a sharp knife you shouldn't be affected by cutting it as much. I hear lighting a candle near your board helps. I've never had issues cutting onions because I wear contacts :D

Try swim goggles...actually works.

I wear my diving mask when I cut onions :) It works wonders!

Cut the top 1st and the bottom 2nd😊 idk why it works but it does😊😊😊

Slice the top or bottom of the onion then rub the area with cold water and voala , no more burning or tears!

The sharper your knife, the less you cry. If your knife isn’t sharp enough, you add extra pressure and it extracts the juice of onion.

Cut stem to stem, and don't cut off the root end. That's where all the crying chemicals are.

Do not cut off the "root" end. Peel it, trim it, slice it but do not cut off the root end until the very last.

Wrap seran wrap around your face covering your nose and eyes tight, don't cut the onion to it's heart, leave a good stump instead and that's where most of the distress chemical is released from

Get you some goggles and breath with your mouth open lol

Stop standing straight over them. Turn on the fan over the stove and step back from your cutting board. Easy fix

You must be allergic then

I chew gum... and I cut up a LOT of onions.. I never shed a tear.. it's the only time I ever chew gum..

Recently a tear-free onion has been created. I hope you are able to use them.

😟

Soak in water before cutting.

Mine do that even when my mom cuts them in another room with the fan on.

Then why are you doing it. Buy frozen prechooped. I am sure that advice is for when needed.

Wear glasses or sunglasses.

Rinse the onion in cold water after peeling and cutting in half. It rises away those fumes

Try my grandma'a trick, above.
