The strange thing is that I just read the thread title and have just realised that my floaters seem to have disapeared and I don't think I've noticed it for a few months now!
I had an annoying 'long' permanent 'floater' for a few years which was probably due to a head injury. My optition told me there was nothing I could do about it. The only things I can think of which I've started doing for the last few months which may have possibly had an effect is drinking lots of water and taking Colloidal Silver . I wonder if that's what it is?
