I've been using the Harbor Freight visor for a long time. It's good for pulling splinters, working with tiny parts, fixing my wife's jewelry chains, and rebuilding atomizers. It's a vinyl product with plastic lenses, but it does the job.
I liked the clip-on models in one of the posts above. That's what I've been looking for. For some jobs, the 2x and 3x reading glasses are good for dealing with close-up work. I found that out one day when I was trying to solder a new mini plug on my earbuds. Old eyes and tiny parts need help!
