Hello - parasite larvae can live in the eyes - pork tapeworms being the most common. It could just be all in your mind - or it could be some baby parasites trying desperately to escape the herbal poisons.
If you had larvae in your eyes - you would have probably known they were there before the cleanse - you would have had eye problems - dry eyes, itching, watery eyes, vision problems and so forth and so on.
Let's just hope your mind was playing tricks on you :)
