Do welding glasses block UV?
Use of protective eyewear while welding helps reduce harmful effects of ultraviolet, visible, and infrared radiation.
What is a gold welding lens?
They reflect 90% of infrared radiation (radiated heat), greatly reducing the heat to which a welder’s eyes are exposed. For convenience and variety, our gold-coated lenses are available in shades 9, 10, 11, 12, and 14, and in two sizes: small (2” x 4.25”) and large (4.5” x 5.25”).
