These are the bifocal sunglasses that separate at the bridge with a patented magnetic connector that allow them to slip off/on easily while still securing around the neck unobtrusively. Ideal for poolside reading, the bridge opens with a firm pinch, allowing each lens to fold inward, creating a compact form for convenient storage—a feature available exclusively from Hammacher Schlemmer. Their nickel-silver frames have expandable sides and back to provide a custom fit for any head size. The sunglasses’ polarized lenses block 100% of UV rays while shading eyes from sunlight. The lenses meet CE, EN1836 regulations, and ANSI standards for scratch and impact resistance. Available in 1.5 and 2.5 diopters. Includes a soft microfiber pouch that doubles as a lens cleaner. Not available for shipment in New York. (6 oz.)
