My mom is mostly blind. If your mom is in the US, The American Council for the Blind is a really great organization. You can give them a call and they'll set you up with someone to get your mom evaluated for her needs. They can put you in touch with professionals to get her assistive devices that are often available at little to no cost, connect her with resources, and more. I'd definitely recommend going that route, because they have the process pretty well streamlined and have a ton of experience working with folks with very different needs.

I'll also note that there are a bunch of great podcasts from blind folks that have tutorials and other information. There is a huge and vibrant community of blind podcasters; if she's into that, I'd definitely point her their way.
