Cobalt Dioxide Glass Lenses. The welding lenses here are designed specifically for soldering, burning, brazing and cutting applications. They are not designed nor suitable for use with electric arc welding processes. Use of these lenses alone for that purpose will come at a cost to your vision and could result in permanent and irreparable harm to your eyesight. Protect your eyes! These lenses are IF/IR blocking and will block infrared energy. They are manufactured from Cobalt Glass and are Blue in color. The gold sputtered lenses have an added amount of IR protection meant to keep the glass (and your eyes) cooler and will absorb UV as well but are not strong enough to protect from searingly high visible light intensity. However; all of these lenses are suitable for top notch protection against Infrared energy produced from non-electric arc cutting or heating apparatuses and processes such as Oxy-fuel cutting, burning and brazing.
