Some tips that have helped a blind relative of mine is using a braille label maker to label buttons such as knobs on a stove, microwave, washing machine, etc. Also labeling your clothes to what color it is. Using apps such as "Be My Eyes" where you take a picture of something or do a live video session where you can ask a large community about what something says like what your thermostat says. Also setting up voice assistants on your phone like Google or Siri or even on your computer like a text to speech assistant such as "JAWS". Helping them look up available transportation services for the visually impaired/handicap in the area. Those are much cheaper than just requesting an Uber/Lyft.

​

Those are just some of the things I could think of off the top of my head.

"Activities of Daily Living" is pretty broad - there is AT and O&M and blind/Low vision tricks for every aspect. There are things (like driving) that cannot be done by people with vision loss - but the list of what people imagine can't be done is pretty long and the reality is pretty short. You might be better off asking more focused questions.

Looking at Money - since someone else brought it up - US Coins are accessible, US paper money is not easy for the blind/visually impaired because it all looks (mostly) and feels the same. Yes, I know they have some tints of color on some new bills, yes this helps, but is not nearly enough.

Here is where your clients can get a free (US only) currency reader: https://www.moneyfactory.gov/uscurrencyreaderpgm.html

Once you know what paper money is what, this wallet (comes in other colors) is useful to store your money (lots of pockets for different types of bills):

The free SeeingAI app on the iPhone can also do currency identification (and colors, and scene detection, and read text aloud). EnvisionAI can do the same things, with bit more accuracy on reading, and is available on iPhone and Android ($2 month or $20/year).

-------------------

My two favorite companies (besides Amazon, which is too broad) for disabilities are www.maxiaids.com (for disabilities in general) and www.lssproducts.com (especially for low vision). There are at least a dozen similar companies - some are more focused on educational products, early childhood, etc. Get some of their catalogs to have on hand and get familiar with the sorts of things that are out there.

At the same time, realize that for many things, you don't need a special version for the blind - you may need a talking meat thermometer, but a plain-turn-the-dial kitchen timer works just fine). Be creative and see how far you can go with what you already have.

Tell people that the gadgets and devices are not a magic bullet. Just because it worked for a friend/cousin does not mean it will work for you. Everyone we see, even people with the same condition, have wild variability in what works and what doesn't.
-------------------

Get VERY familiar with VoiceOver on iOS, TalkBack on Android. For extra points practice using ChromeVox on Chromebooks, NVDA on Windows, and VoiceOver on MacOS.

Make sure you know where your local Assistive Technology centers are and the state programs for the blind in your area.

------------------

Make sure that your clients are signed up with the National Library for the Blind (local chapter in each state, again, assuming US). They will send them a free player if the person doesn't want / have a smartphone or tablet.

Are you based out of the US? US coinage has reeded edges of the dime and the quarter (in Canada, it also has the reeded edges for the toonie). It's the series of grooved lines along the edges.

For coins of similiar sizes (the dime and the penny, the quarter and the nickle), the larger denomination has the reeded edges. It's also easier to feel with the fingernail, rather than the fingertip. Although I believe the American half-dollar coin also has reeded edges, but I'm less familiar with the size (I don't believe I've ever seen one in real life before).

Use a clean ping ping ball to tell when a liquid in a cup or jug or saucepan is at the right height.

Use a 3d//foam sticker to mark the most frequently used setting on washer, dishwasher, oven, radio etc

Maybe use the bumpers for children on furniture for a newly diagnosed person
