Large ones will read a whole page, small ones will read a line at a time. Developed for dyslexic people they can help those of us who can still see where the text is so we can set it up.
There are online programs that will read text for you. Some of them are free but I imagine you get what you pay for, the "free" one loaded down with trackers and the like.
I've found that setting the computer up to have white text on a black screen is a help. My Kindle Fire has a color inversion feature that does the same thing and the WaPo comes with an audio toggle on most of their articles. Audio books are all over the place. Audible is a great source because the books have great readers instead of the monotones found on Talking Books, something that drove my mother bonkers when she went blind. Classic books on audio can be found on YouTube. There are also sites that feature radio programs from the Golden Age of the 20s-early 50s.
My frustrations are that I can't drive and if I get anywhere to shop, I can't see much of anything. I have keratoconus now and the presence of Drusen bodies says I'll have ARMD eventually. I also have Sjogren's syndrome, so contacts are out while I still have some vision. It sucks. There should be only one nasty problem to a customer.
ETA: If you still cook, Ove Gloves are fabulous for grabbing anything hot. They're canvas gardening gloves with silicone stripes on them, so they're flexible. They also don't look as silly as welding gloves. I use a Chinese cleaver for chopping, knowing where the blade is prevents nicks and cuts.
