My Left Eye Keeps Rolling From One Side. I Do

My left eye keeps rolling from one side. I do have Age Macular in that eye. In 2012 I have surgery but it seems last year and a half my left eye keeps moving from one side. And when people look at me they have noticed it too. When people look at me they always start rubbing there eyes. It is so annoying and I need to know what is going on. Please help me
