The Flexon EINSTEIN 600 Eyeglasses combine classic rectangular styling with Flexon's revolutionary memory metal technology for men who demand durability without sacrificing comfort. Crafted from a lightweight titanium-nickel alloy, these prescription-ready frames feature full-rim construction and Flexon's signature flexibility—allowing the temples and bridge to bend, twist, and return to their original shape, even after accidental stress.The clean rectangle shape balances round or oval face features while projecting a professional, structured look suitable for work or everyday wear. Available in versatile Black, Brown, and Gunmetal finishes, the EINSTEIN 600 includes adjustable nose pads for a custom fit and straight temples (140mm or 145mm) that deliver all-day comfort. These metal stainless steel frames accommodate single vision, progressive, and bifocal prescription lenses, making them a smart investment for active lifestyles.Flexon's memory metal construction—developed by Marchon Eyewear and used for over 30 years—ensures these frames resist the bending and breaking common with conventional metals, while remaining lighter and more comfortable than traditional eyewear materials.
