The Flexon 623 Eyeglasses combine timeless round styling with revolutionary memory metal technology for unmatched durability and all-day comfort. Crafted from lightweight titanium-based memory metal, these prescription-ready frames feature Flexon's signature flexibility in the bridge and temples—allowing them to bend, flex, and twist before returning to their original shape. Designed with adjustable silicone nose pads, the Flexon 623 delivers a customized, secure fit that prevents slipping and eliminates pressure points. The classic full-rim round frame in sophisticated metal finishes—Gunmetal, Steel, Coffee, Tortoise Bronze, and Tortoise Natural—complements round and oval face shapes beautifully. Available in 46mm and 48mm lens widths, these unisex frames work seamlessly with single-vision, progressive, and bifocal prescription lenses. More resistant and lightweight than conventional metal frames, the Flexon 623 is built for active lifestyles and everyday wear. Whether you're working, reading, or on the go, these frames deliver the perfect balance of classic style, innovative engineering, and lasting quality.
