Help/resources for a person newly blind at age 91

Regrettably, I have seen that sort of neglect.

Heck, my late spouse was only in his late 50’s when a nurse tried to justify neglecting him (which resulted in a bedsore) with (paraphrase) “who cares about an old dying cripple anyway?”

Just saying it’s something to watch out for. If not seen, great, but you have to watch out for the less compassionate/competent people out there.
