If I am feeling manic as I can usually manage with reading glasses I use a pair of this sort of thing of Russian origin
**LINK**
I'm not sure I would recommend the pair I use as they zoom and focus independently and that is tricky to set up. The working distance is very good though. The link will probably bring up a lot of chinese optics. From my experience they can be surprisingly good. The big advantage they offer is true stereoscopic vision. I have used headband types mostly the ones that RS Components sell which are basically industrial parts but I think they are not as good as these. I'd be inclined to risk buying a cheaper pair of binoc's. Maybe some have dioptre matching for people who have unbalanced eyes. It's important to relax the eye when using these and not to inadvertently try and focus at the working distance – usually more of a problem for the young.
I also find a desk magnifier very useful. I found some of these very seriously discounted
**LINK**
They are little odd hence the discount I suspect. There might still be some about on the web. They have an on off switch and a PRESS to START button. No idea why as the tube does start as soon as it's switched on. It may help when the tube has aged but I've used 3 tubes over 5+ years probably 10+. If I was buying again I would try to get one with a flip up dust cover but I've had no problems from regular cleaning.
For really find work one of these comes out
**LINK**
They crop up now and again and have very crisp optics and a decent working distance even for things like soldering, even working on watches at times. I'm sure if needed a model engineer could mount one on a boom stand. I also have a couple of very capable stereo microscopes but these tend to be a lot more expensive.
