Pro-Performance vs. Performance Series Lenses
Pro-Performance Lenses: These lenses offer a maximum of 92% light reduction; excellent for high-altitute expeditions, rock climbing, and ice climbing. Blue Tundra and Silver Frog lenses feature a flash mirror, pigment base, and back Anti-Reflective Coat. Glass McKinley lenses feature a hydrogen fired photochromic base and pigment back coat. These lenses show minimal fading or loss of protection
Performance Lenses: Darker than an average sunglass, at 88% visible light reduction, the Sierra #3 or Malachite #3 lenses offer good all around performance for everyday activities. They feature a color pigment base, back coat and a multi-layer anti-reflective back coat. Caution! Plastic versions or these lenses are prone to fading and loss of protection over time.

Blue Tundra |
92-93% DENSITY (7-8% VLT) This filter is truly glacier dedicated. The amber pigment base is dense and comfortable, but still retains enough contrast to enhance visibility in hazier or overcast environments. Available in cr-39 resin and Endefin, single vision and multifocal/progressive. |
McKinley
|
Reaches 92-93% Density (7-8% VLT) This filter is photo chromic starting at 80% density in lower light conditions and transitioning to full glacier density in brighter cooler conditions. An excellent extreme exposure lens with some flexibility for other applications such as driving or more pedestrian activities. CAUTION! Extreme cold will also cause this lens to darken even when lighting conditions are low. Other versions of this lens are available for active sport applications. Available in cr-39 resin and glass, single vision and multifocal/progressive. |
Silver Frog

Available In Cr-39 Resin And Endefin, Single Vision And Multifocal/Progressive. |

Polarized Is Not Recommended Where Accurate Judgment Of Surfaces And Terrain Are Critical, But Is Ideal For More Leisurely Hiking And Other Outdoor Activities |
Malachite MGD
|
Malachite MGD 88-89% Density (11-12% Vlt) The Malachite Is Also A Marginal Glacier Density Lens, Identical To The Sierra, But With A Gray-Green Pigment Base Offering Truer Color Perception, But Less Forgiving In Hazier Or Lower Light Conditions. This Filter Is Also Available In Polarized Or Non-Polarized Versions. Polarized Is Not Recommended Where Accurate Judgment Of Surfaces And Terrain Are Critical, But Is Ideal For More Leisurely Hiking And Other Outdoor Activities. |
