The Eye Fatigue Preventing Reading Glasses.

Infused with melanin, these magnifying reading glasses prevent eyes from tiring as you read or view a computer monitor. By age 65, eyes lose about 50% of their reserves of melanin, the pigment that gives eyes their color, protects from UV damage, and reduces glare naturally. The synthesized melanin in the lenses compensates for aging eyes' increased sensitivity to glare by filtering out not only ultraviolet light, but also "high-energy visible" blue/violet light, the next most damaging spectrum. And though the lenses appear to be tinted, they in fact enhance the perception of true color, as naturally occurring melanin does. The lenses are treated with a scratch-resistant coating for long life. The stainless metal alloy frame features adjustable nose pads, integrated spring hinges and a polished brass finish. Specify magnification: 1.25, 1.5, 2.0, or 2.5. 1 1/2" H x 5 1/2" W. (5 oz.)
