because onion have some liquid inside it wich is known as CV when we cut onions it relieves those CV which goes in our eyes and tears fells from our eyes or The synthase enzyme converts the amino acids sulfoxides of the onion into sulfenic acid. The unstable sulfenic acid rearranges itself into syn-ropanethial-S-oxide. Syn-propanethial-S-oxide gets into the air and comes in contact with our eyes. The lachrymal glands become irritated and produces the tears!
