Dom, you can find most of it online at www.central-fixation.com/bettereyesight.htm.

I refer to it as 'The Book' just as a joke, of course. By which I
mean, The Cure of Imperfect Sight Without Glasses. You can find that
book on the same website.

See my other post, 'Where Can the Books Be Found?'. I have listed all
the sources.
