Safety glasses feature ForceFlex technology that incorporates a patented, multi-injection molding of the lens with a flexible, thermo plastic urethane (TPU) frame. TPU allows these glasses to achieve a military ballistic-level impact-resistance at more than 1000' per second. TPU material also allows the frame to flex and fit individual faces from large to small for unparalleled levels of protection. Dual material temples combine thermo plastic rubber (TPR) and polycarbonate for comfort and durability. Lens blocks 99.9 percent of ultraviolet radiation.
