Featuring a one-of-a-kind SpringFlex™ temple, Springerdelivers 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 for wider faces, a bowing or straightening of the lens may take the eyewear out of compliance. The soft thermoplastic rubber TPR temple tips and nosepiece provide all-day comfort. Springer offers our standard anti-fog protection. Also available with smoke lens (BKFLEX-4010S).
Certifications and characteristics

About the Springer
Springer’s SpringFlex™ temple design can’t be bent out of shape! Bend it at a right angle and watch it spring back to its naturally curved, molded-to-fit-the-face form. The pliable TPR temple tips provide a secure fit without uncomfortable pressure points. Two-piece durable polycarbonate lenses block 99.9% of the sun’s ultraviolet rays.
