Hi,
The blip page is when your right eye and left eye both see the center crease of the book then bring both creases about 1/4 inch or so. This makes a rounded hump type thing combo of right and left page but very small and rounded like taking half of each page and rounding it over the center to make a third small rounded bit in the center of the book.
Hope this isn't confusing you still have both full pages in your vision but don't try to read anything just focus through the book at your feet or a bit in front of your feet.
That is my best explanation of the blip page.
just bring both creases about 1/4 inch or so a part then you will see the blip. When I first starting seeing it I played with it making it bigger and smaller not sure what it was suppose to look like until I made it just a bump down the center of the book.
That's about it.
