I had woke up with my right eye goopy and red which had never happened to me before. I tried a couple of the remedies on this site (ACV & Lugols Iodine)to no avail. I read a post regarding colloidal silver, which I actually had in my arsenal of natural cures. I tried one drop in each eye in the Am and Pm for 2 days and it is nearly cleared up! Best cure for this issue for me. It didn't burn or sting and got rid of the redness so fast!
