Lots here in a previous thread

I particularly like this bit from that thread by /u/drillinstructorjan

Please come back with more questions once you have processed that thread.

Just be willing to help when neededd, read things to her and so forth. My sighted wife died over ten years ago, but I still miss the things we did. We'd play the poker machines in Vegas and she'd automaticly glance over and read me my cards while she was also playing. There is lots of talking things out there these days. Lots of little tricks you learn like running cold water over your arm and hand before taking something out of the oven so you can touch something hot for a fraction of a second befgore it actually burns you. Best of luck. BTW, I'm 73 and been blind all of my life. Is it a pain in the ass, absolutely. Harder from going from some vision to none I know.

Get some training from places to learn how to do things from being independent to traveling around the world well okay not exactly but mobility skills. Learn how it works and start using it maybe try a training center? I just learnt by myself but that’s me.

Learn assistive technology now.
