I started working on the little cooper carving and decided to invest in a pair of these* in the hopes that I could achieve a higher level of precision than my current capabilities. (That's the roundabout way of saying that my 46-year old-eyes don't see as well as they used to.)
The carving isn't much to look at yet, but the progressive shots in the group photo give you an idea of the magnifying capabilities of the four lenses that are included in the box.
Powers of magnification include 1.2x, 1.8x, 2.5x, and 3.5x—more than enough for my use. A tiny light that runs on batteries will probably stay in the "off" position (unless I take up coal mining) because I keep a task light attached to my bench.
The headband is adjustable and comfortable, and the instructions are lots of fun: "Under sunshine, please do not put it at window or at the focus of combustibles."**
So far, I'm well-pleased with my purchase.
And, while I don't want to get so wrapped up in details that I never complete the project, I am hoping that the lenses will help me become a little more accurate.
Oh, and the other cool thing about these glasses? They add a bit of pizazz to my Steampunk ensemble.

**I do not mean to offend non-English-speaking individuals. I think the turn of phrases within the instructions is charming.
There are other visors/magnifiers on the market, but these are the only ones I've tried. If anyone has had good luck with another brand, feel free to let everyone know in the comments.
