In the last ten years my eyesight has gone from 5.75 to 3.50, and I currently think I want to go down from that, maybe to 3.25. That is substantial. One large jump I noticed immediately after supplementing with an entire dropper full of Iodine at once. I also developed a bromide "bump" that essentially hemorrhaged on my back. Since we are inundated with bromide continuously, I believe that this was a probable culprit in blocking Iodine to my thyroid and my developing nearsightedness at the old age of 11, suddenly, after being able to see just fine previously. There are numerous claims on the internet for this theory, although of course since we aren't special "white coats" and will receive no help from one, us dum-dums have to go about this all on our own, as our own guinea pigs. I don't know why its so difficult to think that Iodine could effect the eyes? If you've come to CureZone aren't you here looking for alternatives?
