Tell me about loupes! I see there are many options! Or is optivisor the way to go? Lighted vs standard….. etc? What is your go to device for seeing the grind on the cab.

If you wear everyday glasses, loupe's work ok, but take some time to get adjusted and used to.......Optivisor's do not work with glasses but will compensate for that need and you may find yourself lifting them on & off quite often.
I wear everyday glasses, but use to use lighted optivisor's when working on small RC motor's, wiring and control mechanisms.....I preferred them over loupes......for rock and stone inspection, since I don't perform fine cab or wheel/disc polish (jewelers magnifying lenses are all I use now)......however, either lighted type of loupe or visor would be useful while performing the tasks you are involved in.......visor's are easier to keep clean too......!

I have the Harbor freight $5 lighted head piece w additional loupe that can be pulled down over one eye.
I also have a lighted loupe from Amazon with two lenses on it.

I use the Optivisor. I don’t like any of the lighted head magnifiers. The lights are too heavy. Optivisors come with interchangeable lenses, and you can add a small magnifying eyepiece to any of them.
To check cab scratches, I wear the Optivisor, dry the cab, and go stand in the sun, or hold the cab under the Genie lamp. Works well.
I find loupes difficult to use. Hard to close one eye, and keep the other open.
My Optivisor fits over my glasses which I wear all the time.

I wear progressive bifocals full time - but for cutting I like lined bifocal readers bought online, used with a cheap visor.
The progressive lenses don't play well with the visor lenses for me, but one fixed magnification area and one with no magnification works okay. The visor I have has lenses larger than an optivisor lense, so I can look through the upper part of the readers and through the visor lense for cutting. For a closer look I pull the visor down slightly and look through the lower bifocal lense and the visor lense.
Using a 2.5x (second "weakest" one) visor lense keeps the focal length long enough that I don't have to bend over closer to the machine to focus.
For examining "microscopic" scratches or surface defects I use this: www.sciplus.com/10x-triplet-loupe-47885-p . This is the best loupe Ive ever owned. It works so well we have at least three of them here.

I use bidocal safety glasses and usually have the optivisor nearby in case I need it.

I use an Optivisor (can't recall the strength) along with a loupe for close inspection. I look pretty funny while cutting with the Optivisor perched high on my forehead and my drugstore magnifiers on the tip of my nose with a space between them so I can see across the room. I can manipulate the Optivisor for reasonably tight viewing or the glasses for fairly close-up vision.
I've used a Belomo 10X loupe made in Belarus for years, which is built like a tank, is very reasonably priced and has excellent optics. But visiting with Vince @hummingbirdstones2 recently I used the one he recommends in his post above and liked it a lot. Excellent field of view, no aberration to speak of at the edges and the light helps enormously. Thanks Vince, for the link. I just ordered 2 more of them.

I use a 10x loupe between grits without an LED added light. Really helped me see the scratches I miss at 600 and 1200 grits.

I use the Optivisor (technically a cheaper version bought on eBay) while cabbing. I'll start looking through them after the 220 stage. I prefer the ability to flip them up or down rather than having to grab a loupe to see the scratches.
The loupe is fun to put up to the phone camera to take pictures...which I saw your denim pic...so I know you know what I'm talking about! LOL

I wear Optivisors for both lapidary and jewelry. The one with the #5 lens gets the most use, a comfortable compromise between magnification and field of view/working distance. I use my #10 lens Optivisor when discovering and dealing with cab scratches that shouldn't be present. I also use the #10 for stone setting and graver work. Note that the Optivisor lens numbers are not the magnification levels. An Optivisor #10 lens is not the same as a 10x loupe. Here are the magnifications for their lenses:

I have an optivisor but didn't like it. I buy a bunch of cheap 4x readers. I break them and lose them and buy more. Lighting is as important as eyewear. I come inside, clean the lenses and use an ott light to inspect.
