I do alot of sewing and alot of crafts that i need to really see close up. I've been looking for something that I could use so I can see better when working on small things like jewelery. These glasses are great and just what I was looking for because you wear them like glasses and they have a light and different magnifications that are easy to just switch out for the one you need. Better yet no batteries! you just charge them with a usb.They come with a head strap to so you can keep them from falling off if your moving alot.
