I've got a magnifying visor I use with 2.5x and 3.75x optics for it.
It's an OptiVisor, made by Donegan Optical Co in the USA. Woodcraft
sells them. The 2.5x is about right for most work; the 3.75x is for
the tiniest parts.

I'm starting to get "old eyes" but with the visor I can still hand
solder down to 01005 caps (16 mil x 8 mil):
