Hey thephotoreader
Practice the photofocus state all the time. Where you diverge your eyes and they separate. For me, I apply it to everything. For instance, a pen might be close by and I pick it up and do the photofocus step making the pen appear double. I do this with my knife and fork, a couple, lightswitch, anything at anytime. Eventually your eyes will become naturally divergent and the most incredible thing will happen to you.
You will get to the stage where you can see the whole page, all the writing clearly, where someone else who doesn't know about photofocus will only see one word clearly or a few words a best.
If you do nothing else, do this. Practice the photofocus whenever you can.
