As we age, our eyes naturally lose some of their ability to focus close-in. A teenager can focus on objects as close as 3" but by age 50 that distance can increase to 18" - VERY frustrating when it limits your work or hobby. This premium-grade lamp is a simple and effective solution for seeing almost anything bigger, better and brighter. 38" triple-joint arm has unique internal cantilever system (not external springs like lesser lamps) that lets you adjust without loosening/tightening knobs - perfectly balanced to hold position (can be locked in position if necessary). Features a sleek & modern closed-arm design for precision movement without the annoying finger pinches.,arm,focus,lamp,
