Onions cells contain traces of sulfur, that are broken and released into the air when cut. These sulfured compounds react with the moisture in your eyes forming sulfuric acid, which cause the burning sensation you feel. The defense mechanism of the eye is to create tears to dilute the acid. So your tears protect your eyes from damage.
