3-Diopter Rectangular shaped magnifying lens "stretches" the 5-inch circular viewing area to 6.75 inches.
Wider viewing area allows for comfortable vision with both eyes and reduces eyestrain and fatigue. Visual scanning speed is increased because more surface area is magnified.
Powerful 18-watt compact fluorescent lamp (included) produces 130 footcandles 15" above the work surface.
Lens is made of crown-optical glass. 6.75" x 4.25".
IV-pivot models for use with floor stands (sold separately).
