I've never had an eye parasite, but I have had pink eye so that is an infection. Have you considered trying raw honey? It burns a tad but it I used it and the next morning my pink eye was gone. Ancient Egyptians used honey for all types of infections and ailments. The honey will NOT harm you because it is natural. I simply used an eye dropper to administer it. Google if you will for proof but I honestly would not post this if I had not experienced this. About 2-3 drops will suffice maybe 3 or 4 hours in a row the night before. You have to mix the honey with distilled or (bottled) water, let it cool and apply to each eye. 2 teaspoons honey and 4 teaspoons water. Your eyes will tingle and tear up (crying not ripping) but it will help you. Honey is also known to lighten eye color gradually overtime. It is best to use the raw or pure honey with no added Sugar if at all possible. I hope this will help you. There is no need for you to suffer and again this is not something you have to ORDER and pay excessive amounts of money for. You probably already have honey and bottled water. I simply microwaved the water about one minute, mixed in a bowl, let it cool and then applied. Pink eye is not attractive so I was desperate to get rid of it!! Really hope you get better soon. Bless!
