The reason why your eyes water isn't because it gets in your eyes, it's because it gets into your sinuses.
What happens when you cut an onion, acid is released into the air and we breath it in through our nose and whammo, the sinuses are attacked from stuff they don't like and in response to that, our eyes water.
Solution.......
While cutting onions, breath through your mouth and not your nose, most people tend to close thier mouth when doing something.
If your eyes water still, which is still very possible, take a few very deep breathes in through the mouth and this will help to clear the sinus distress.
Quite simple really. Hope this helps.
