Blurry vision was one of the main, main symptoms I had that something was really wrong with me. At first I just chalked it up to age, but it got to the point where it was ridiculous. I also had (and still have) episodes of eye twitching. I now know that both of these problems are common signs of heavy metal poisoning. Since I've started chelating, the blurry vision is all but gone. I still get the twitching once in a while, though.
