Radnor Dynamo Series Eyewear features a full frame design, constructed with a revolutionary shape-memory material, which provides unique flexibility and resilience. Light and pliable, this material allows the frame to temporarily bend shape and then return to original form. The Dynamo Series lens is made from a tough polycarbonate with a special scratch-resistant and anti-fog coating. The lens is manufactured with 99.9% UVAUVBUVC protection and in compliance to UV 380nm and ANSIISEA Z87.1+ 2015 safety eyewear standards, to prevent and minimize injuries from eye hazards. In addition, the Dynamo Series also has a R+U6L3 optical radiation rating.
