I've only read one e-book and it was on my laptop.
Overall, I don't like reading much at all. Maybe it was because it was on paper. Like you, very little seems to sink in. I prefer to watch TV on a TV. When I watch on a tablet, I miss a lot.
I'm 70 years old and definitely prefer a Kindle over paper books: no mustiness, no holding pages open, and you don't have to turn on a light at night to read. I can change the type size and font to suit my needs.
I don't know what your problem is about reading from paper, however; that sounds like a psychological problem, not a physical problem.
