Over the last week my right eye has started to water a lot the moment I start applying mascara or eye liner. It can't be an allergy, because my left eye is fine. It's not painful, and stops after about 5 minutes, but my eye looks a bit of a mess by then!
Could it be an overactive tear duct? And why would this suddenly occur?
It's only a minor problem but beginning to be annoying
Any ideas?
