right. my vision dramtically improved just by chance. happens all the time, just ask an eye-doc (and wait for them to laugh at you). come on doc, while you are waiting for that double blind study that will never happen, or never be done correctly, i will be recovering my eyesight. I don't care about the study, i already proved it to myself, as have many others. people come here because they are looking for options their doctors won't even tell them about. try as you might, its a trend that you cannot stop.
if you wear glasses as i suspect you do, check out the Bates Method. vision problems are really about mental strain. you don't even realize the strain you live with every day.
