BKFLEX-4010

Featuring a one-of-a-kind SpringFlex™ temple, the Springer delivers our face-hugging fit in an unprecedented way. The temples adjust to wider facial profiles by gently bending at a built-in pivot point created by a molded spring in the temple itself. Why does this matter? When rigid spectacles are pulled wider than their natural structure to accommodate a more perfect fit for wider faces, a bowing or straightening of the lens may take the eyewear out of compliance. All of Brass Knuckle’s Flex temple eyewear prevents this outward bowing — but Springer does it like nothing else. Add to that soft thermoplastic rubber (TPR) temple tips and nosepiece in stylish sky blue, and Springer sails to the top of the class in style.

About the Springer
