I have no idea if this would work for anyone else, but I had dry eyes last year for quite a while. My eye, especially my right one, was constantly tearing up. Very annoying!

I read a post on Facebook that a person used castor oil for dry eyes. I bought organic, cold pressed castor oil and started rubbing a drop or two into each eyelid each night before bed. Within a month, my dry eyes were cleared up, and it has not returned in a year. Like I said, it may not work for everyone, and I certainly am not giving medical advice. I am merely relating my own experience. If it helps someone else, great!
