For the past 2 years I've had various floaters in my eyes. Most floaters are drops of blood from the retina, but my floaters were mites or worms.
I used "Eye Relief Eye Wash" by Bausch & Lomb early on, but floaters are in the vitreous fluid inside the eyeball and just washing the surface of the eye doesn't do much good.
I've had much better luck with putting a drop or two of Colloidal Silver in my eye. Just pull out the lower lid to make a pocket, then using an eye dropper, put the silver in the pocket. It may sting for a few seconds, but that's all.
My eyes do not seem to be harmed with the fairly strong silver I am using.
