I am having some eye problems as well. I found out I had Ascaris roundworms in my intestines, have taken humaworm and now in waiting period to take it again.. I believe I have a hyperinfection because I feel crawling throughout my body, including my face and eyes. Nothing intense, just feels like someone tickling me with a feather... For the floaters and eye crawling, I have tried eyebright eye wash..it doesn't work. The doctors say my eyes are fine, but it certainly doesn't feel that way! I hope you find relief someday, I know it must be hard. I am going to try and get a zapper and hopefully this will help things somewhat along with the herbs(very expensive though). I was also going to try a few drops of coconut oil in my eyes each night, to see if it works..couldn't hurt I guess. Here is the post that I found the info on https://www.curezone.org/forums/fm.asp?i=1731265.
Best wishes to you in your parasite journey!
