The Wens Lens Ultra Cool Blue (Original and Electric Ice) is 2 pieces of glass adhered together surface to surface with an optical adhesive, preventing any debris or moisture building up between the 2 glasses. The bottom side is the actual welding filter which gives the welder protection from UV and IR rays and meets all required welding lens safety standards. The top side is a new technology glass which has the mirror coating built within the glass which prevents it from being scratched off and also extends the life of the lens. This new technology glass has a definition/clarification enhancement and filters out all except for Blue Lightning.
