Barton takes its name from our favorite local swimming hole, Barton Springs, where ROKA was born. This versatile, modern square frame has classic aesthetics that can go anywhere, and it's packed with technology. This new and improved second generation version features advanced GEKO™ grips for a secure, non-slip fit, and custom-fabricated spring hinges that provide a bespoke fit for each person's face. It's as essential as it is durable and will stand up to any challenge. And just when you thought these frames couldn’t get more powerful, we added our advanced Wind Down™ lens technology to help improve sleep, reduce stress, and protect your mood. Put them on and feel the difference.
