While cutting an onion helps your produce tears, it is a reactive process that does not help you produce at a steady rate every minute. While your eyes tear in the presence of the onion, you cannot really function on the computer or work while you hang out with that onion.
Please do see your local Optometrist for dry eye needs, diagnosis and proper treatment.
