Well, I quite understand your confusion over that feeling. As far as I know, there must be something that trigger your eyes' reaction. Maybe you are not used to some occasion, such as strong light, or maybe your have got red eyes. So, allergic reactions will give rise to watering in your eyes. My advice for you is to find out the sources of that and do something to tackle the problem.
There must be some problems for your eyes which may get the inflammation. You'd better go to see the doctor. Or else, the continuing watering from the eyes may cause your discomfort. And during this time, you'd better have a good rest for the eyes and not east the spicy food.
Well, in my opinion, it may relate to the dry eyes. Generally speaking, your watery eyes are often a sign of dryness. As we know that tears are for lubrication and for keeping your eyes clean. So when your tear glands don't work in a wrong order, it may develop dry eye syndrome. In other words, if your eyes become dry and uncomfortable, the tear glands react by producing large amounts of tears. Anyway, it will be kind of dangerous for you to have this kind of symptom. So you should go and see a doctor. So that you can make sure what happen to your eyes. Also, infection and allergies are also the causes of your symptom.
