My head visor has very, very low quality plastic lens, which is annoying for anything longer than a brief look. The big advantage with the head visor is that it's much easier/faster to put on and remove. However, when removed it will take a lot of space on the workbench, so it's better to have hooks on the nearby shelves/walls and hook the visor there when removed.
Maybe I should try to attach a pair of glasses to the visor, instead of its original plastic lens.
Another thing I've tried was to work under a big lens (~10cm/4inch diameter) the consumer type, made as a knitting aid or such. The lens is meh, not very good but bearable, yet its diameter is still too small to solder, and not very practical. Works OK as an aid, for example to keep a breadboard under the lens and make occasional rewiring, or move the measuring probes without reaching for glasses, things like that. Overall, the knitting lens wasn't practical for daily use.
At one of the working places we used to have a similar size single lens on a lamp with an arm, a professional one made specifically for fine work (don't know the brand). I didn't like that one either. The lens was good, made of glass, but it was heavy and was oscillating when touched, or even oscillating with the workbench (which workbench was an office desk).
