Lens Information

Our lenses can be broken down into 4 categories: Tinted, Polarized, Mirrored, and Photochromatic. They all have benefits and limitations respectively.

Tinted Lenses

More scratch resistant than mirror finish lenses.

Yellow & Orange tint help to increase depth perception and sharpen features so they work best in overcast or stormy conditions.

Rose or Pink tints perform best in flat light conditions. They offer enhanced depth perception with sharpened features, perfect for dusk or low light conditions.

Smoke tints offer the best protection on bright, sunny days. And lets face it they just look so darn cool. As they filter out most of the sunlight they can reduce the amount of glare coming off of the snow. The only downside to this is that it can be difficult to gauge depth and terrain variances on overcast or darker days as little light penetrates the darker tint.

Clear lenses will offer the best performance for extremely low light. These are best during heavy snow or night conditions. They will allow for maximum light penetration, providing contrast within dark areas of the snow to increase overall visibility.

Polarized Lenses

More scratch resistant than mirror finish lenses, It cuts the glare from the sun almost completely so that you can see better no matter what the conditions. While a mirror can reduce glare by 10 to 20 percent, polarization will reduce 99 percent of glare. Beyond cutting glare, polarized lenses increase contrast and definition so you’ll find reduced eye fatigue after a day on the mountain or trail. However because of the manufacturing process these lenses undergo it makes them the most fragile lens.

Mirror & Chrome Finished Lenses

These lenses have a thin mirror coating on the outside of the lens that blocks and reflects light coming into your eyes on sunny days and can bring out shadows, increase contrast, and offer better depth perception. They are as durable as a tinted lens, but are the most susceptible to scratches.

Photochromatic Lenses

Photochromatic lenses are lenses that darken on exposure to specific types of light, most commonly ultraviolet (UV) radiation. Once the light source is removed (for example by walking indoors), the lenses will gradually return to their clear state. Photochromatic lenses may be made of glass, polycarbonate (ours), or another plastic.

Photochromatic lenses contain millions of molecules of silver chloride or another silver halide embedded within them. These molecules are transparent to visible light in the absence of ultraviolet rays, which is normal for artificial lighting.  When exposed to UV rays, as in direct sunlight, the molecules undergo a chemical process that causes them to change shape and absorb portions of the visible light, causing the lenses to darken. This process is reversible.  Once the lens is removed from strong sources of UV rays, the silver compounds return to a state which allows all light through.

Additional Information

Our lenses come with a one year warranty against manufacturing defects. Please review our lens care as stated in our goggle instructional guide (included with initial goggle shipment) as well as the information below as it is very important to not use anything other than your goggles soft pouch when cleaning. Also, direct heat sources should be avoided as it can cause the lens to bubble and/or the coatings on the lens to become damaged or compromised. Please let us know if you have any other questions or comments.

The 509 soft storage pouch is made of the premium choice material to clean and polish your lens. First, rinse the lens with water to remove all large debris, being careful not to scratch the lens. Then shake the excess water from the lens and blot dry and polish the lens with the 509 soft pouch. The pouch may be hand cleaned and allowed to dry if it becomes soiled. Never use a cleaning agent on the lens as it can remove the fog and scratch free properties from the lens and/or ruin the clarity of the lens immediately. If you experience icing on the inside or outside of the lens, warm the goggle to melt the ice before wiping it away as ice can be like charred glass on a lens and leave scratches.

Cleaning Your Goggle Lenses

Clean the lens as listed above. With the lens removed, use mild soap and water on the foam, frame, and strap, and rinse thoroughly with water and air dry. Sweat, dirt and debris is the leading cause of foam breakdown followed by improper goggle removal from the helmet and lastly, improper storage. Removing goggles carefully from the helmet and storing in a hard case in gear bags are two of the best ways to give your goggles long life expectancy.
