Eye exam for bed bound senior?

Call a Nursing Home and see what doctors come in to see tge residents.

For me readers alone would not to the trick. If you Dad wears prescription glasses to see regularly, readers won't help. He needs bifocals. If he sees fine without glasses then readers should be OK.

If he's only wanting glasses for reading, why not just pick him up some inexpensive reading glasses at your local drug store(you can pick up several different strengths appropriate for his age, and return what doesn't work)and save you and him a lot of worry/concern about finding a mobile eye doctor. That might be the easiest solution, don't you think?

And as far as dentists, I know that there are some that do visits to nursing homes and such, so that will probably be easier to find for him, as you can most likely just "Google" that.
Good luck.

Do you have the prescription for your brother’s last pair of spectacles? If each lens is the same, or very close, good chemist specs of the next strength up could be a big improvement. If you don’t have the prescription, take his current pair to a chemist yourself and test them against the many options there. Then get a stronger pair.

I used to use opticians specs until I discovered by accident that my eyes were the same, and that chemist specs at $20 were just as effective as optician’s lenses and frames at $250. I was furious that it had taken me 20 years and many opticians before I knew – opticians don’t go out of their way to tell you. Of course this doesn’t work if there is a bigger problem, but it’s certainly worth checking.

I was looking around for some possible answers for you & came across a program that UCSF has a program for eye exams for home bound seniors. Perhaps you can contact them & see what they offer.

It seems that they also have a Geriatric Medicine Department that could possibly be of use for your brother. https://geriatrics.ucsf.edu/patient-care/ucsf-age-friendly-health-system/ucsf-care-home

Best of luck to you & your brother.

I’ve known of dentists who visited homebound seniors. It would help if the senior has previously been their patient. Call and ask. Same thing with eye doctor.
