Ideal for examining the finer details of stamps and coins, tying flies, or simply threading a needle, these are the hands-free 2X magnifying lenses that are worn like eyeglasses and provide clear resolution of minute detail. Made by Eschenbach, renowned purveyors of precision eyewear in Germany since 1913, each lenspiece may be individually focused to ±3 diopters. The magnifying glasses contain no sharp edges, and are flexible and lightweight enough (less than two ounces) for comfortable extended use. While not designed as a substitute for reading glasses, they are optimized to focus on objects with a working distance of 16", and the lenses are made from durable scratch-resistant PXM plastic. Not available for shipment in New York. 1 1/4" H x 5 1/2" W x 71/2" L. (1 3/4 oz.)
