I had tried the Bates method two years ago with no results myself. Although, I was expecting a clear flash immediately, but anyway. A year later I picked it up again and have so far had mild success. I found a ton more info than I had had previously, including different interpretations of it, other people's additions etc. So now 6 months later, I have had several 20/50 or better clear flashes, increased acuity at all distances (it's still pretty bad though), better body condition etc. There are a large number of different methods, and the key is to find what works for you. So if this works, Yay! If not, keep searching.
