I can't wear things on my face or in my eyes, so these work great instead. Also the magnification increases when folded over so can look through them folded together when I want more of a magnifying glass effect. Folded out for 2 lenses it works better for reading and such, just like glasses that you hold up to your face--without the arms for ears in the way.The string it comes with is not useful, but I didn't want to use that anyway. I had my own in mind. I put a clock pendant that matches it on one side and this on the other. I usually wear it with this in front and the clock in back, and they counter weight each other so they don't sit against the back of my neck. This is great because I can't wear wrist watches either, and the back of my neck has issues with necklaces otherwise. This has solved many issues all at once for me.I thought I would have liked it without the extra extension and large hole for hanging, but find it is really nice for putting my finger into when using it (and also when figiting, which I am prone to do--this keeps the lenses cleaner than they'd be without it).The colors go great with blacks, browns, blues, goldens, and pretty much everything I wear that isn't formal. I still wear it with formal things, just underneath.
