I'd build experience before "facts" and what others tell me be they from word, book, or teacher.

I have had results. I just didn't keep it up. I also had improvements that I attribute to Qi cultivating practices.

My strength/nutrition coach, who I consider a friend and peer as well as someone I pay for services has had quite a few clients who have gotten rid of thier glasses using the Bates method.

Its actually starting to become more common. In the US their are more and more eye docs that are having clients come in and do eye 'exercises'.

I have also talked to people who have done it.

But the biggest thing for me is that I have seen pretty big differences in my own vision. Enough that I was comfortable not wearing my glasses while driving. How stressful the day was made a difference also. After training for example, especially if I pushed it a little, i wouldn't drive without them. But as I stopped doing the relaxation exercises etc I started to need to wear them all the time again.

That proves to me through experience that it can be ajusted through exercise and life style etc.

You might say its only temp and that can be an issue with this. According to The Bates Method once you improve them there are maintanace exercises that you can do in minuets (say sitting at traffic lights etc) I didn't stick with it long enough to get where I wanted and either way I didn't do the maintance. But I did see substancial results.
