The Tana™ ECO safety spec offers an incredibly lightweight (21g) and flexible design, yet remains resilient and durable for all day wear. The snug-fitting wrap around lens provides a wide and un-obstructed vision, with wide and deep temples for additional protection. The universal nose bridge helps the spectacle contour to most faces and the side arm design allows for a compatible cord to be fitted. Part of our innovative and market leading sustainable eyewear range, the Tana™ ECO safety spectacles are made using recycled materials and environmentally friendly bio-based manufacturing processes. The side arms are made from 99% recycled Polycarbonate. This significantly reduces the amount of virgin resources required in the supply chain and reduces the CO2 from 4.7kg per 1kg of production to 0.02kg. The bio-base manufacturing process reduces CO2 production by 50% in comparison to petroleum based material.
