It’s important to note that the older the onion, the stronger the fumes. Buying smaller batches of onions might ensure that your onions are fresher.
Hacks that have worked for us:
1 – turn on the overhead vent before chopping
2 – freeze the onion for 15 mins before chopping or store your onions in the fridge
3 – wear goggles
Hope this helps!
