    I am going to try this, but I’d really like to know why it works. Someone else suggested cold water on the knife. Do the irritant molecules from the onion react with the water on your hands/wrists/knife before getting up in your eyes?

      Onion make gas. Gas stick to tear on eyeball. Tears turn acidic, eyeball hurt.

      Bring tears to onion, gas already react so no can hurt real eyeball. That why bring water (fake eyeball) to onion when cut.
