I have a congenital superior oblique palsy that for years has made it very difficult for me to read books, especially while lying in bed as being on my side puts strain on the oblique muscles. I used to end up just having to stuff one eye behind my pillow and read with the other so I don't keep seeing double text, and I would get sleepy very quickly as my eyes would get very tired. As a result, I slowly gave up on reading books altogether.

Recently, my gf gave me her kindle to read a book on it. I had never read on a kindle before, though of course I had read a ton of things on a computer screen and on a cell phone. I found that it was MUCH easier for me to successfully fuse and read even while lying in bed without seeing double. I could read for much longer without getting tired, and didn't have to manually suppress one eye. I ended up buying my own kindle and I now read all the time.

I think a big problem with reading physical books while having difficulty fusing is that the lighting across the page can be uneven or can change a lot unless you are holding the book in the exact same place all the time. Also, the page is sometimes a little curved or at least not perfectly flat. Finally, the fact that there is always a left page and a right page means that there are two reading positions, one of which puts more strain on my paretic eye. With an e-reader, the screen is lit uniformly, is perfectly flat, and there's only one "page" to read. This makes it a LOT easier. I also use a slightly larger font and hold the kindle further away from me, making it much easier to fuse.

Has anyone heard from people with oculomotor issues who found that e-readers provided huge benefit?

P.S. just to clarify, I can fuse most of the time and for most of my field of vision, what gives me trouble is gazing to the right, and if I'm VERY tired I start to lose the ability to fuse even looking straight ahead.
