I'm sure you can get adjustable ones, but I suspect they'll start to get
into real money. The cheap ones I'm familiar with have all been fixed
and I can't remember running across adjustable ones.
An alternative is to mount the loupes onto an old pair of glasses.
If you can wear contacts, that also works.
On the high end, your eye prescription is integrated into the loupe.
There are 2 types of loupes: Galilean or Keplarian. Higher
magnification (>= 4X) are primarily Keplarian which incorporates a
prism for a longer internal optical path. The cheap Chinese loupes
are primarily Galilean. (One type is not necessarily better than the
other, they're just different construction)
Here's a buying guide I ran across which might be useful.

I'm interested. Do you know of a set with one-eye focus adjust? I'm way more nearsighted on the left than the right.

Don't know. It focuses at about 8 inches in front of me. Wearing them takes getting used to, but it lets you work at a "normal" distance. I guess it's a YMMV situation, but I am quite pleased with my pair.
Chinese unbranded optics seem quite good, I bought a bunch of telephoto and macro and fisheye lenses for my phone and they are quite good.
