@judimahoney Thanks so much for this caring and helpful reply! I do need to get in touch with the Alzheimer’s Association again (we were on a weekly Zoom call with them awhile ago, but my husband was discouraged and scared by hearing people’s stories who were further down the path). We do have a headlight; what a great idea to try! Thanks again!

@judimahoney --

thank you for your input, but I'm afraid his vision loss (total in one eye and almost there in the other eye) is due to glaucoma. He quit driving about 8-9 years ago, and it has thankfully been a slow process. Then on top of that, in December, he was diagnosed with cancer in the "good" eye! Just found out the first three months of treatment (chemo drops 3-4x per day) for a week--and then continuing to suffer with burning and itchiness for another 7-8 days--has been working; however, I'll need to continue giving him those drops 3 more months to eradicate it completely, the eye doc says. It is a celebration for those two weeks and we try to do satisfying things together.
The main problem is my husband never had any other hobby except country dancing--and that's been over for many years now. He just loves to work (was a general contractor and electrician) and has had trouble stopping! He does listen to a lot of audible books and music...but falls asleep if he doesn't keep moving. Yes, I think the dementia is causing great anxiety--no paranoia yet--just angry with me for hiring someone but it's time!
I'd have to say his very red, swollen, angry eye causes me to be much more sympathetic and loving. Prayer and a book I recently purchased: "Stronger Than Stress" 10 spiritual Practices to win the battle of Overwhelm"
by Barb Roose has been helpful! Real practical ways to destress. I highly recommend it!
