The rectangular shaped magnifying lens "stretches" the 5-inch circular viewing area to 6.75 inches. This wider viewing area allows for comfortable vision with both eyes and also reduces eyestrain and fatigue. Visual scanning speed is increased because more surface area is magnified at any given position. The 3-diopter lens is made of crown-optical glass and measures 6.75 by 4.25 inches.
Dazor uses a powerful 18-watt compact fluorescent light source because with proper illumination levels, magnification requirements are significantly reduced. This lamp is a stitcher's delight!
