Bates Method book in Spanish?

I regularly get SPAM about a "program" where you pay $100 or $50 or less to get a package to improve your vision. I just got one today. It is always the same thing: Bates' book from 1920 and some trinkets. This time I decided to download the original version of the book and, more important, look for a translation to Spanish.

The English version is at http://a42.com/site/pg/downloads/entry/other-documents/bates-method-for-... should you want it. It does work. I want a Spanish version because my sobrina has poor vision that is getting worse. I decided this was worth mentioning here for two reasons:

  1. Maybe someone has a Spanish version.
  2. A for free vision improvement method could help lots of people in Nicaragua and, well, the Americas.
