It does read rather strangely, but I totally get what she's saying. I too suffer from dry eyes, and you do end up producing more tears than people who don't.
If it's anything like why I have dry eyes that is! My problem is that the tiny oil glands in the eyes which secrete a layer of oil which films over the top of the tears to slow down the evaporation are blocked. So the faster the tears are evaporating, the faster I'm producing them It's not comfortable at all. You have to use a hot compress over your eyes and then massage the eyelids several times a week (up to several times a day in severe cases).
is this called bilateral bletheritis
