The Flexon E1111 eyeglasses deliver professional style backed by serious engineering. These men's rectangle frames are built with Flexon's proprietary memory metal technology—a titanium-nickel alloy originally developed for aerospace applications that returns to its original shape after being bent, twisted, or dropped. The full-rim metal construction features a clean rectangular profile with textured temples that add visual interest without sacrificing the frame's business-ready aesthetic. Memory Metal That Actually Works Flexon memory metal isn't marketing speak. The temples and bridge incorporate a titanium-nickel alloy (NiTiNOL) that flexes under stress and bounces back to shape. This means the E1111 can handle the daily abuse that breaks conventional metal frames—tossed in a bag, sat on, or knocked off a desk. The material is also significantly lighter than standard stainless steel, so these frames sit comfortably through long workdays or extended wear. Adjustable nose pads let you fine-tune the fit, and the 17mm bridge accommodates a range of nose widths. Available in two lens widths (54mm and 56mm) and four finishes—Black, Brown, Gunmetal, and Navy—the E1111 adapts to different face sizes and personal styles. Prescription-Ready and Built to Last These frames are fully prescription-ready and compatible with single-vision, progressive, and bifocal lenses. The full-rim design provides maximum lens security and works well with higher prescriptions that require thicker lenses. The structured rectangle shape complements round and oval face shapes by adding definition and balancing softer features. Flexon has been refining memory metal eyewear since 1988, combining Japanese materials and manufacturing precision with practical American design. The E1111 represents that legacy—durable enough for active lifestyles, refined enough for professional settings, and flexible enough (literally) to handle whatever your day throws at it.
