Put a cushion or some support on your lap the angle will improve and make it a little easier to get the blip page. I usually elevate the thigh that the book is resting on by resting my foot on something.
Now do what is comfortable. The book can be as close or as far from your face as you are naturally accustomed to. You just don't want it that close that as you turn the pages it brushes your nose, (it tickles 
and that gets a tad distracting).
