material; glass lens, plastic frame.
uses; anti radiation, barrier against the outside light on the eyes of the effective, safe and durable and comfortable to wear.

electric welding glasses features and use: eye protection lens, high strength welding workers effectively block 99% uv. In the welding process caused by intensive irradiation and avoid splashing into the bead. The lenses used colorants mainly iron oxide, cobalt oxide, yellow - green, can absorb all the following 500urn wavelength light, visible light transmittance below 1%, only to have a small amount of infrared light through
