Lots of folks switch back and forth between HUMAWORM and prescription meds. It will just be hard to find a doctor to prescribe the meds. Any parasites in the eyes will die and will get worked out of the eyes. Eyewashes using an herb called "eyebright" will help. Get the eyebright tincture that is preserved without alcohol and thin it down OR boil the tincture to get rid of the alcohol if it has any in it.
