Don't worry. It is not dangerous, but very uncomfortable. Tear is very important to eyes, because it can nourish cells, kill bacteria, wash out the dirts and lubricate eyes. Glands in eyelids are produce tears. After eyes are lubricated, tear will travel down to nasal cavity through internal path. Once this path is blocked, tear can't get drained so that your eyes would be very watery. The dirts and bacteria would accumulate at the corners of eyes so that it is very easy to get infection. You might find blue and green thick discharge. It is so annoying rather than dangerous. The good way to bread through the blockage is massage at the corner of eyes and near to the bridge of nose. Keep wash your eyes clean with saline solution, which can help control infection. Apply some warm compress.
