My dentist has these binocular-looking things that hang over his regular
glasses.

Search ebay for "binocular loupes -lamp -light". They come in all
shapes, sizes, and magnifications. I find that 2.5x is about right
for me, but if you need more power, 3.5x is common.

Anybody have something that works in this respect and which does not
cost an arm and a leg?

Well, $40 is about typical for a binocular 2.5x x 420mm that clip onto
existing safety glasses. Here's an example:

Add about $20 for the LED illuminator.
