To contact users. Have you ever noticed that onions don't bother your eyes when you cut them?

I recently had lasic surgery and now it seems like onions just kill my eyes. I have worn contacts since 1991, and haven’t shed a tear while cutting them ever. Until now. Granted, my surgery was the one where they cut a layer off of your eye and it grows back, not the one where they cut a flap. Anyone else ever notice this? Is that normal? I miss my contacts for that reason only.
