Parasites/Floaters???

When I close my eyes and look into the light I see these Cell Worm like images.
I have no idea what these are. They come and go sometimes, but mostly are there all the time. I can`t seem to find any info on this matter and thought this might be the place to start and get some answers. So, are these so called Floaters, or are they some type of parasite that I can not get rid of. I`ve tried cleansing(liver, intestinal, and a good parasite cleanse) and nothing has helped yet. Please advise, any help on this matter would be very much appriciated. Thanks in advance, Bob Tweet
