These are the readers with unique pivoting arms that allow the glasses to flatten to just 7mm thick. Designed in Italy, the glasses have a blended-nylon frame that folds above and below the lenses, rather than behind them, making them prized for being lightweight, pliable, yet durable, with hinges at the temples so they fold to less than half the thickness of traditional glasses. With scratch-resistant methacrylate lenses—the same material that shields the cockpit on fighter jets—the sturdy, ultraslim readers slip conveniently into a shirt pocket and come with a hard case. Specify strength: +1.50, +2.00, +2.50, or +3.00. Not available for shipment to New York. Black. 5 1/2" L x 1 1/2" H x 1" D. (2 1/4 oz.)
