What can i do for an eye that won't stop tearing? tear blocks are open

Dry eyes?: You can think of excessive tearing as a sink that is overflowing. It is either that the faucet is on too strong, or the drain is clogged. If your tear drain is open, then you are making too much tears -- a sign of dry eyes. Your eye is trying to 'wash' away damage on the surface of your eye caused by the dryness. Try otc artificial tears 4x/day to see if it helps.
