You might have been facetious, but FYI, the favored theory for the cause of normal myopia is insufficient UV light exposure during childhood. Eyestrain and close focal distance are not thought to produce it even though the latter is correlated with low UV light from being indoors.
There is at least some support for myopia being associated with close focal distance activities, as mentioned in this meta analysis:

In particular, my article discusses randomized experiments and the opinion of multiple disagreeing experts. Your article (also from 2015) is a meta analysis of observational studies on the correlation between near work and myopia, not the overall question of myopia origins. As far as I can tell, I don't think they try to test whether light exposure is the underlying cause, nor does you article claim represent the opinions of anyone besides the three authors.
I welcome links to more recent and comprehensive reviews, though. I definitely don't think this case has been closed.
As to bindings, I've always been a fan of spiral bound books.
There's also the Japanese style of printing shorter books in multiple volumes (at least I think this is the case - correct me if I'm wrong).
Given my aversion to paper-based reading, I've enjoyed using my Kindle, smartphone, and tablet to read. However, now there's two more problems. First, my smartphone is a constant source of distraction (calls, texts, work emails, personal emails, app notifications, etc.). Second, it feels like I spend the majority of my waking life looking at either a computer screen, a smartphone screen, or a Kindle screen -- it's kind of unsettling.
