No,it is not that hard to cure.And here I will recommend some home remedies to you here.First of all.prepare some purified water,and the cool purified water would be better.Of course you should pour the water in a container that can contain your whole face.Next,you should soak your face into the container for a few min.After you soak your face in the water,you should keep your eyes open and blink again and again.It is good to your contaminated eyes.Another way I plan to introduce to you is in relation with hot water.Prepare some hot and purified water, a clean handkerchief,cotton balls and some cold and purified water,then the first step is to soak your handkerchief into the hot water,and next put this handkerchief on your eyes,FYI,keep your eyes closed.Make sure this hot compress can last two min.Next you should soak your cotton balls into cold water for one min and then apply them to your eyes instead.Last,dry your skin and eyes with a clean and dry towel.Are both the two ways very simple?I wish this could help you.
