I’m a commercial building systems engineering consultant and business owner, and have been visually impaired for >30 years (juvenile type of macular degeneration onset as an early teen). While I’m partially signed, I generally follow this space (though do not claim to be an expert). +1 for this suggestion of starting by reaching out to your State if you’re in the US (or other government entity if outside) as a starting point for assistance. My state’s division for the Blind and Visually Impaired (DBVI) resources have been very helpful over the years. They provide adaptive tech kit for free (e.g., iPads, PCs, large screens) and software/instruction for those who need it). The OP didn’t indicate whether their grandparent is retired (suspecting so?) but in that case, sometimes the State’s path is a little different—they put a huge effort into workforce development, and sometimes different efforts into adaptive tech & services for folks not intending to return to the workforce. In our state, there is an association for the blind that I believes handles more of those cases (but I don’t know for sure). I’ll also give a +1 for everyone I know who is blind and visually impaired having an iPhone. It’s possible that platforms could be nearing parity now, but in the early 2010s there was just zero competition. I use iOS built in accessibility features every day and they have (not exaggerating) changed my life from an accessibility standpoint. TL:DR - Yes go to your state, definitely good with an iPhone, built in accessibility features are amazing.
