Hi Practo user,
Nasolacrimal duct causes to drain tears from eyes to nose. If it becomes block by any cause the it leads to tearing eye. There is no need to open it to go tear in proper way. To do this the best option is regular massage is very effective. Press and release both eyes corner nasal sera by thumb and index finger. Do this frequently 10 times in a day. Gradually it'll be open the blockage. Do this and provide your valuable feedback.
