M4+LED 4" Inch Round 4x Double Lens LED Illuminated Magnifying Glass
This is the most powerful 4" magnifying glass we are aware of period! it has double lenses which allow this high magnification for a 4 inch lens. The replaceable LED bulb provides efficient bright light and the large lens provides very good light reflective light transmission. The lens has a very wide field of view and a forgiving focal length for those with not so steady hands. It takes two "C Batteries (not included). Most highly recommended Magnifying Glass for all stages of AMD Macular Degeneration.
