Hello, taltal, and welcome to the forum!
I don't exactly have what you described in my face as a whole, but I can relate to what you're saying about your eyes. I often feel like there is something in mine, too. Sometimes an eyelash will come out and go in the eye because I have Blepharatis (a chronic inflammation of the eyelid.) Very often, as you say, there's nothing I can see, but my eye will still be sore and feel sticky. It can get very uncomfortable indeed.
