The flip-front welding goggle features a soft frame with lift up front lens holder and high impact non-chipping lens. The goggles will fit over prescription spectacles. The flip-up portion of the goggle consists of Shade 3 infra-red protective lenses and clear polycarbonate cover lenses. The cover lenses fitted into the goggle are clear impact resistant polycarbonate lenses to offer protection while chipping. This is ideal for the helper and should not be used by a person doing the welding. Always wear a full face welding helmet.
