I don't like cutting onions

I've literally never teared up or had any issue chopping any variety of raw onion? Am I special?

no, your onions are old

Do you wear contacts or glasses?

One thing you can do OP is literally wait til the last moment to do your onion prep. Do all cutting board work, and set it all aside and do the onions last.
It has a lot to do with your sharp knife, and how much pressure you apply to the onion to break up the cells that produce the gas. Sharper knife, it goes through like butter. Work quickly, doing the root end last, scrape it into a bowl, quickly clean the knife and board, then ventilate and walk away. Glasses do help as do goggles if you have a large batch. It's sulfuric acid, so it's going to bother everyone's eyes eventually.

Cut them into halves and then quickly rinse them under running water - no more tears.

>no more tears
It helps a little but there will be tears

Bullshit, you just gotta be more thorough with the rinsing then. I normally tear up very easily but not after doing that.

Don't cut the root off, cut through the root, then slice up to it, dice across and dispose of the root immediately. No tears here!
