Filter Lenses for Welding Helmets and Goggles

Replace the filter lens on your welding helmet or goggles. These lenses reduce glare and filter out harmful infrared radiation. They are available in shade numbers 4 through 14.

Rectangle

Green Lens—Use green lenses for welding applications. They increase visual contrast so you can see the weld pool without making the environment too dark.

Cobalt Blue Lens—Use cobalt blue lenses for metalworking applications such as torching and brazing. They enhance visibility by filtering out intense light produced during metalworking. Do not use for welding applications.

Colored Welding Lenses

Improve visibility for more accurate welds than standard welding lenses. These lenses reduce glare and block certain colors to make it less painful to look at your weld. Only use these lenses in combination with standard green lenses in your welding helmet. Do not use them in place of standard welding lenses.

Rectangle

Blue Lens—Blue lenses block yellow and orange light and improve depth perception. They’re often used for carbon steel or pipe welding.

Magenta Lens—Magenta lenses block yellow light and flares better than green and blue welding filters. They are commonly used when welding stainless steel.

Laser Welding Face Shields

The lens on these shields filters out harmful light to protect your eyes during traditional and laser welding. The curved design offers better peripheral vision than laser welding goggles and additional face protection from impact, sparks, and radiation. To meet ANSI Z87.1 standards for eye protection, wear these shields with compliant safety glasses. Customize the shield’s fit by twisting the easy-turn knob on the ratchet adjustment.

ANSI Z136.1—They meet ANSI Z136.1 specifications for laser safety.

Visible Light—Visible light is the percentage of visible light that passes through the lens. The lower the percentage, the more light is blocked. Make sure enough light passes through to see your welding work clearly but not so much that it becomes dangerous.

Optical Density @ Wavelength—Optical density indicates how much light a lens absorbs at a specific wavelength. The higher the density, the more UV, infrared, and visible light is blocked. Powerful lasers often require an optical density of 5 or higher.

Shade Number—Shade number indicates how much light is filtered by lenses. The higher the shade number, the darker and more protective the lens.

Laser Welding Lenses

Replace scratched lenses in your laser welding helmet or goggles. These lenses keep harmful UV and infrared light from damaging your eyes. Do not use with regular welding helmets or goggles.

Close-Fit Face Shields

Flip-Up Lens

The snug-fitting goggles attached to this face shield add protection from dust, liquids, and debris. They are designed to fit over most prescription glasses.

Flip-Up Lens—Shields with a flip-up lens are ideal for switching between tasks. Flip the shield down for full face protection, or flip it up when you only need to protect your eyes. You can also detach the shield when it’s not needed.

Shade Number—Those with a goggle shade number protect your eyes from infrared light, such as during light brazing and plasma cutting.
