For reading, have you considered audiobooks? Since you don't know how the degeneration will progress, it might be easier to start listening to books rather than magnifying and reading them.

Additionally, I would strongly recommend seeing a rehabilitation counselor at some point. They might also be able to better tools.

I agree about seeing a rehabilitation counceler. While it's good that your concerned about her vision loss as someone who isn't blind or trained in teaching blind individuals independent living skills you don't know the questions to ask for things as simple as how will she cook a meal on her own, match clothes etc. while reading is important basic skills so she can continue to have independence is also important.

You could also look at screen readers, BTW. Can recommend Google TalkBack for Android. iOS has its own which is also quite good based on what I've heard.

Voiceover on iOS is really good. I'm totally blind and have been using it since 2010. One thing to consider is that when using a screen reader bigger may not be better. When I've used an iPad, I've had issues with spacial awareness finding things on the screen because it's so large. I don't have these issues on the iPhone. I realize that if someone still has some vision then bigger may be better.
