What would be the best lens material to dispense a welder?

The best lens material to dispense a welder would be polycarbonate. Polycarbonate is a type of plastic that is known for its impact resistance and durability. It is also lightweight and comfortable to wear, making it an ideal choice for welding applications. Polycarbonate lenses also offer excellent protection from ultraviolet (UV) light, which is important for welders who are exposed to high levels of UV radiation. Additionally, polycarbonate lenses can be treated with anti-fog coatings to help keep them clear while welding.
