Hi Rajka970, Very original discussion, seriously, I haven't seen this one around yet which is pretty weird as it is something we all face one day, or face everyday, I hope not. Anyway to answer your question. When you chop an onion a substance containing sulfur ( or often written as: sulphur) vacates causing our eyes to react.
