My brain sees "brain glyphs." I'm far-sighted, in PhotoFocus, and flipping pages upside-down. My brain sees the characters as almost like a foreign alphabet. When I noticed this, I went onto the rest of NOPS during the PhotoReading session. I owned it (MY brain glyphs)!. I played with it (This is how I know I'm in PhotoFocus, my Inner Mind can read this faster than the Latin alphabet), and I stayed with it until the end.
Essentially, you're not dealing with the "normal" channels of reading. You're bypassing certain parts of the brain in order to store the concepts in preconscious memory.
