There are several versions of optics for working with small devices. I don't do surface mount devices, my hands aren't steady enough. But I do do 1/10 inch through hole work. The most widely known is a 4 inch round "bench glass" with a fluorescent ring around it.

EDIT: The Northern one has an incandescent lamp behind, higher end units have a "Circline" lamp.

They tend to be a little costly these days, but some alternatives do exist. Horrible Fright carries a smaller version, 3 inch I think, mounted to a weighted base. The lens is acrylic, maybe 2X, but has a
spot lense that is double that. I modified the base to use a bench clamp from a larger version. The illustrated is suitable for bench or desk. They are much cheaper than the larger version.

Then there is a device called an "Opti-Visor". It is available from many sources, some good, some not so good, and some simply trash. Mostly they have acrylic lenses, some with several sets of varying strength to suit the work involved. I use one occasionally, but not often because I have problems with one eye.

Any of these will leave your hands free for soldering, or any other work that requires both hands. I have several examples of each, their use depending on what I am working on or with.
