Zeiss 3x VisuLook Classic Aspheric Hand Magnifier: 12D-AR Coating
The 70mm (2-3/4") diameter magnifier is the best all-around choice for close examination of document appraisals, and similar situations where high magnification is needed. It comes with a felt-padded lens case. Zeiss Multilayer Anti-Reflective Coating is highly recommended to eliminate the distracting glare of sun or room lighting which can bounce off of uncoated glass surfaces and make viewing difficult. Coated lenses are a must for long periods of detail viewing, especially when you must work outdoors or under fluorescent ceiling fixtures or other uncontrollable lighting.
