If the original inventor of sunglasses could see, feel and wear Gargoyles Kinser sunglasses, they'd say the art and science of sunglasses had achieved greatness. One look at Kinser and you know every detail was considered with purpose and dedication. The combination aluminum/magnesium top brow provides lightweight strength, while the TR90 NZZ that comprises the lower rims offers resilience and flexibility. The spring hinges, rubber temples and rubber nose-rest work together to make Kinser so comfortable you may forget you have sunglasses on. Protection is also key, so the lenses exceed ANSI Z87.1+ standards for optical clarity, high mass impact and high velocity impact. The antireflective and Tri-Tech oleophobic treatments reduce and reflect light as well as make for easier cleaning. Sure, you could call these mere sun protections. But they're Gargoyles. That means they protect from much more than the sun.
