I have very strong memory's of crying my eyes out when chopping onion as a kid, I even used to wear swimming goggles some times to save the eye watering pain.

However, this just doesn't seem to happen anymore, I can chop a whole pile of onions up and not a single tear or squint, not for years and years.

So have onions changed or have I become acclimatised?

I think some can be worse than others, but it's possible they have been bred to be less so?

I think it depends on the onion. white spanish onions that are very mild won't really hurt your eyes. Stronger tasting yellow onions are more eye watering.

From what I've heard (and from my experiences) the crying starts when you start chopping away near the root area of the onion.

I use the same knife for doing onions.......

I find garlic worse than onions, most onions seem pretty weak on the eye watering stakes these days (I believe it has been bred out somewhat).

I've found that it's all about freshness..
No matter whst size or variety..
With in reason..
The harder it is to peel the more tears..

Maybe you changed technique. If you cut into the root then it bleeds the fumes. If you avoid it, then your eyes won't water. There is some Gordon Ramsey video on youtube on how to cut an onion and he explains it in that.

I wash them under the extractor hood hehe

And then wash your hands with COLD water - hot water tends to burn the smell on to your fingers.

I wear hard gas permeable contact lenses and couldn't understand why people used to "cry" when chopping onions. The other month I didn't have my lenses in and started chopping......I understand now.

However I don't get why a 1cm diameter bit of plastic placed in the middle of the eye would prevent onion tears.

Open your mouth when chopping.

I heard that its something to do with onion drawing water from your eye so if you open your mouth it stops your eye watering.

Dunno if its true or not but it works for me most of the time.

Also not cutting through the root helps.

Onions contain a gas which is released when the onion is cut. This gas (an irritant) naturally looks for a moist surface - and as gas rises, this means your eyes are (normally) the first moist contact (unless, as someone mentioned earlier you open your mouth).

Top tip: ALWAYS cut onions as close to a running tap as possible, and you'll be fine.

Bit of trivia for you - make sure you have a sharp knife. As per ExtraT's reply, the sharper the knife, the cleaner the cut and less 'gas' is produced (something to do with slicing the cells rather than crushing them).

I seem to recall that a certain high end knife maker uses an onion to demonstrate how sharp his knives are ie. no tears when cutting.

So my brains not just a hat rack then.

I find when peeling Garlic, if I get any under my fingernails, it's really painful. Often wondered what in the Garlic causes that.

Dead simple. Now you are taller, so your eyes are further away from the onions.

I've come to the conclusion it's a combination of:

A) Sharp knife, I'm always sharpening my Japanese chef knifes so they are always super sharp!

B) Straight from the fridge

C) I'm taller now and further away from the blighters ;-)

Apparently cold onions cause it less, also you get accustomed to onion fumes so the more you chop the less you are affected. I have very sharp knives and still get onion eyes a bit so I'm not sure how much difference that makes.

Onions in the fridge! I bet you keep them beside the bread.

Just learn how to cut them properly without going through the root and you'll be guaranteed no more tears.

Keeping onions in the fridge? nono

Especially not in a plastic bag - they'll sweat and rot.

I keep mine in a cool corner of the house in a string bag. I buy 5Kg at a time since I really do use that many.

I do agree about the strength though. Try a supermarket onion / shallot against a home-grown version and see (or not through the tears) what the difference is.
