Functional safety sunglasses are now fashionable and comfortable with a sleek wraparound design. Not only do they look cool (less laughs from fellow co-workers or the kids at home), the wrap-around design completely covers the eyes for greater protection. Lower lens provides magnification for those of us with well-used eyes (available in four diopters – the higher the number, the greater the magnification). Distortion-free, polycarbonate lenses are hard-coated to protect against scratches. Tinted gray, these safety glasses sunglasses block 99.9% of UVA rays and 82% of UVB rays. Transparent gray frame is made of durable polycarbonate. Soft polymer nosepiece keeps glasses in place.
