The Edge Eyewear® Kazbek safety polarized glasses feature a flexible, durable black wraparound frame. Soft thermoplastic rubber nose pads and Edge-Flex temple arms help create a comfortable, nonslip fit. Polarized Aqua Precision blue mirror lenses maximize visual clarity and contrast in bright light conditions. Anti-reflective ions are infused into the blue-colored mirror to reflect light. The addition of a polarizing filter increases clarity by reducing glare.
