Text blurry is fine. Just avoid forcing it by going cross-eyed. You want to be relaxed looking through the monitor / page gaze. That is if the monitor or page were suddenly taken away your focus would be sharp on an object about 4 to 6 inches behind it (not important where exactly) Just grab a book, take it outside, focus on a object some distance away from you and then slowly pull the book up into your visual field about 12 inches in front of your eyes without changeing your focus (it's still on the other object). Notice the blip page.
Thats what you see when you gaze in the middle of the book. The point an imaginary X would cross if you drew a line from the outer corners of the book. At the same time you that you are looking at the center crease you notice the corners of the book as well. Unlike with regular reading where your mind only sees the words in an area of perhaps 1 inch in diameter. With Photoreading your mind sees both pages of the open book (or the whole monitor screen in one instant.
The only thing you need to move are your hands to turn the pages - your gaze remains in the center of the book. Remember to blink and breathe
