This simple, attractive large unisex frame comes with Axon’s therapeutic lenses and is made of titanium memory flex material. It’s light and bendable – twist away. Wide, curved lenses and the partially-rimless frame make this a great choice for maximum visibility and minimum peripheral light. Color: Gunmetal, Size: Adult Large, 56-20-135, Weight: 18 g/0.64 oz. Without lenses, this frame is a mere 0.12 ounces. This is our lightest frame. The SKYE FLEX is a smaller, more feminine version of our popular FLEX CURVE frame. The frame is made of flexible titanium. Don’t mistake the flexibility for flimsy – you can twist, bend, or pull the frame and it always goes back to its original shape. A perfect minimalist, lightweight design. The lenses are curved so that the frame wraps around the face to block out peripheral light. The nose pads can be adjusted for fit and comfort. This is a medium frame size 58-16-140 and weighs 18 g/.64 oz.
