Guy thanks for support, but I am still struggling with the blip.
I am able to see blip when I cross my eyes a bit and than the cylinder is not empty, but it contains text.
As soon as I move a right page it desapites immediately, so that is probably wrong blip.
Anyway, just to have it clear. The blip will appear in that way that the middle line (where left and right page are connecting) and which is a bit darker than the page due to shaddow will duplicate and than I will have a feeling as if I were looking at the cylinder, right?
Should I play with my eyes in that way to go from cross to divergence?
I am able to see a whole book at once, and the text is blured, but that bothers me because I cannot be sure that I'm in photofokus...
I'll take a day or two rest, and continue than.
Thanks
Regards
