Welding Lens - Polycarbonate Lens  
. Size : 85 x 108mm, 90mm x 110mm
. These transparent covers are placed on the outer layer of a welding helmet's auto-darkening lens to protect it from damage.
. They are typically constructed from high-transparency, optical-grade polycarbonate (PC).
. Using these films prevents blur, reduces scratches, and blocks welding slag and spatter, which extends the life of the more expensive inner lens.
