Conveniently examine a full document without the need to reposition the page. Specially designed Fresnel lens allows for full page 2X magnification of a reading surface up to the size of a standard sheet of paper. Molded 1/16" thick, optical-quality acrylic lens provides optimal performance and a clear image, while being strong enough to stand up to daily use, without the weight that would be associated with a similarly-sized conventional lens.
