After I ran out of wash, I stopped using it. I found that my sight did improve, the ones that were the worst either moved or disappeared. I will add that I seem to either have more or notice them more when I'm sick or congested. It makes me wonder about the congealing gel theory. I made the wash from eyebright herb by making a strong tea. I'd make enough for a couple days and use an eye cup, looking from right to left, up and down for a few minutes. It does burn so be forewarned.
I'd be very interested if anyone's found anything that "loosens" things up, whether natural or prescriptions, even if it's a secondary result of some other treatment. I would like to completely eliminate them, but only if it's a lifestyle choice I can make easily (like eating different foods for example or sun exposure, etc) I'm not prepared to do an eyebright wash every day for the rest of my life. Not for the few floaters I have anyway.
