RE: Magnifier for Detailed Work
Previous poster suggested OptiVisor. Totally agree. A head-mounted OptiVisor enables taking your magnification anywhere you take your head. I have multiple workstations so I'd have to move a clamp-style portable magnifier lamp whenever I go from one workstation to another or from basement where I normally work to upstairs for a quick detailed task up there. Whereas with a light-weight OptiVisor, it just goes where my head goes. And the lens frame quickly hinges up and out of the way while still on my head for normal sighting tasks inbetween detailed magnification tasks. I really like the OptiVisor.
OptiVisor produced by Donegan Optical company in Kansas. Variety of lens magnifications. Here's Amazon suite of OptiVisor headband magnification options.

You can purchase lenses separately; however, they cost about 60% of what a fully-equipped head band costs. When I was researching them, I wasn't sure about the magnification options for my uses. In 2011, I opted to buy 2 headband sets: a 3 diopter (1.75 magnification) and a 5 diopter (2.25 magnification). I also opted to buy a Quasar LED Lighting System ...

I find the 3 diopter lens with Quasar LED Lighting System is a good all-around package. You can get a 2.5 magnification single loupe to mount on your headset for those occasions when the added magnification is helpful. It swings out of the way when not in use.

So, a 3 diopter Optivisor headband with Quasar LEDs with 2.5 magnification Loupe is an optimal suite for any kind of detail work. Have had no lens scratches in past 8 years ... just take care of handling/storing them.
