What Paul said about how it does not matter if the text is blurry as we photoread it seems like a paradox. I realize that there may be something that I don't know about our visual system, and if one of you notice that I don't know it, then I would really appreciate someone explaining it to me. It's just that it doesn't seem to make sense that the brain can perfectly make sense out of very blurry images sent to it by the eyes. What I mean by blurry is poor optical resolution of the image. I just need to be sure that I understand Paul correctly on this subject: it does not matter at all if the images being sent to the brain are extremely blurry or sharp.
