I’ve used jeweler’s eye loupes for extensive periods. They’re not terrible to hold in place unless you’re sweaty. If it’s too small it can become hard, but it generally rests in your eye well and is held in with friction rather than muscles. I do have a set that clip to my glasses now, which I need as I’ve gotten older. Those are easy.
People who only need correction in one eye get glasses with a prescription in one eye, and a plano lens in the other, which is just a clear lens with no correction or adjustments.

It’s interesting to hear from someone who used something like it. I never even thought about how much sweat would be a problem.
It even makes my regular glasses slip down all the time. Some frames/pairs are better than others, but it’s hard to escape.
