I bought this for my wife.  She doesn't like wearing her reading glasses while shopping.  She keeps asking me to read the lables for her.  With this magnifying glass necklace she has a pretty necklace to wear and can just lift it up and read anything she wants.  She loves it!  She wishes they had more designs.  Anyone who doesn't like digging out there reading glasses just to read an item or two, this is a great way to go.  She doen't need to carry her glasses around with her, which she says makes her purse heavy.
