Welding tip: use the double layers when doing the welding work. Do not use eye directly contact on the welding point all the time. It is the most glare point. Move the eyes a little bit further away from the welding point. The double layers of protection filter out infrared and ultraviolet light and allow visible light to come through. The large pieces OD3 are for face protection and see-through for the work-piece and machine operations.
