Flexon adds vintage style to these men’s Einstein 600 eyeglasses. The rectangular rims are made in a lightweight metal that's strong and durable. The wire-core temples curve inward gently for stability behind the ears, and feature comfort-coated tips for extra comfort when you wear them longer. With their distinctive keyhole design at the upper rim, these glasses add an elegant touch to your everyday look, even if they're not protecting your eyes from dangerous gravitational forces while you work on your next theory of relativity.
Flexon eyewear combines innovative 'memory metal' engineering and contemporary design elements to yield eyeglasses that suit your lifestyle—and your fashion sense. This groundbreaking eyewear line for men and women features frames made from a lightweight, flexible titanium-nickel alloy—so even if you drop or bend your frames, they'll return to their original shape.
