I have dry eyes n sensitivity towards dust. So i use tears naturale ll and during eye infections i use zylopred. But whenever i apply zylopred, after the application there's a white precipitate kind of a semi liquid that accumulates in my eye. Is it normal or should i stop using zylopred. I've got a brand new pack too because of this and it was fresh, still the problem persisted. Although it does not irritate in any way, still i just wanted to know the details. And should i wash it off after application or let it be.
