I photocopied a magic eye and anytime I had a minute at work I would practice looking at it until I could get it instantly. Then I took my copy and anytime I starting Pring I would have the copy right above my page, I would get into photofocus and pratice holding it and slowly made my way from the Magic Eye to the page I was starting to read. Once I could do this it was just a matter of holding the focus while I turned the pages. Hope this helps you
