Frequently Asked Questions
Sunglasses Prescription Technology
How do I clean my Smith sunglasses?
Do not use any paper products, including kleenex. First, blow any dust or grit off the sunglasses and rinse under running water before wiping. (Do not use any other liquids on your Smith sunglasses.) Gently wipe the lenses with a soft micro fiber cloth, such as the Smith Smudgebuster.
What is the benefit to the Tapered Lens Technology (TLT Optics) found in all Smith models?
Visual distortion occurs when light waves hit an aggressively-curved lens causing it to bend or distort an objects true size or position. Imagine looking through a fish eye lens. What your eye normally sees, is stretched beyond reality. Get the picture? Tapered Lens Technology corrects the distortion by progressively tapering the lens from the optical center towards the outer edges. Light waves are thereby delivered straight to your eye resulting in zero distortion and true optical clarity. What you see is what you get. Carbonic lenses are engineered to be the most impact resistant lens material in the world. Injection molded with Tapered Lens Technology for optical precision and a high level of protection.
What is polarization?
Polarization is like noise-canceling headphones for your eyes. Glare off of horizontal surfaces like snow, water, and asphalt, decreases depth perception, reduces visual acuity, and causes eye fatigue. We precisely align the polarized visual layer inside our lenses to filter out 99.9% of this 'visual static' for a finely tuned view of the action. Carbonic lenses are engineered to be the most impact resistant lens material in the world. Injection molded with Tapered Lens Technology for optical precision and a high level of protection.
How does a polarized lens reduce glare?
Smith's polarized lenses utilize energized iodine crystals that are positioned in vertical rows on a thin piece of film and provide the protection you need. This film is sandwiched between two layers of lens material or injection-molded material to create a molecular bond. The filter within the lens allows selected light rays to reach the eye while absorbing reflected glare or polarized light. When a polarizing film or filter is properly positioned in front of reflected light rays, the glare is blocked. Carbonic lenses are engineered to be the most impact resistant lens material in the world. Injection molded with Tapered Lens Technology for optical precision and a high level of protection.
How are Smith's polarized lenses constructed?
Smith's polarized lenses are constructed of a sheet of film that is sandwiched between two pieces of lens material. We then add layers of anti-scratch protection, multi-layer mirror coating, and a hydrophobic coating that will repel water and moisture. The PVA film molecule alignment is such that it allows only vertical light waves to pass through the lens (somewhat like a venetian blind), thus eliminating glare. Cheap polarized lenses do not use these materials and can cause distortion in your vision, which may eventually lead to headaches.Carbonic lenses are engineered to be the most impact resistant lens material in the world. Injection molded with Tapered Lens Technology for optical precision and a high level of protection.
How can I tell if my sunglass lens is polarized?
The easiest way to check the polarization of a lens is by holding the lens you are inquiring about over the top of a lens that you know is polarized. A liquid crystal display (LCD) or digital watch is polarized. Hold the lens over the watch on a horizontal plane and rotate it. If the lens is polarized, you will notice the watch display appears darker as you rotate the lens above it. If the lens is not polarized, there will be no visual difference as you view the watch through the lens. Carbonic lenses are engineered to be the most impact resistant lens material in the world. Injection molded with Tapered Lens Technology for optical precision and a high level of protection.
Do you have polarized lenses for the Sliders?
Yes. Smith Optics offers Polarized Bronze Mirror, Polarized Platinum Mirror, Platinum Mirror, Polarized Sienna Brown, and Polarized True Color Gray lenses for all of the current Interchangeable models. Check out our Replacement Lenses for your model.Carbonic lenses are engineered to be the most impact resistant lens material in the world. Injection molded with Tapered Lens Technology for optical precision and a high level of protection.
What is the difference between Sienna Brown and True Color Gray polarized lenses?
Sienna Brown polarized lenses, while minimizing glare, increase contrast and depth perception. Sienna Brown polarized lenses are ideal in flat light or low light to enhance shadows and add contrast between reds, oranges and yellows. True Color Gray polarized lenses minimize glare while enhancing natural hues. True Color Gray may seem more soothing to the eyes and are recommended when consumers ask for the darkest polarized lens available. Read about all of our lens tints in our technology section.
What is polarchromic?
The glare stopping benefits of polarization meet tint shifting photochromic magic in the most advanced lenses we have ever created. Versatile and comfortable, Smith Polarchromic lenses automatically darken or lighten as a response to the level of light you are exposed to.
How are carbonic lenses different from other lenses?
Carbonic lenses are engineered to be the most impact resistant lens material in the world. Injection molded with Tapered Lens Technology for optical precision and a high level of protection.
How does the hydrophobic coating on your Smith sunglasses help?
The hydrophobic coating repels moisture, grease, and grime. A barrier between your lenses and the world. Water will bead up and disperse without streaking. Smudges from fingerprints are wiped clean easily. Carbonic lenses are engineered to be the most impact resistant lens material in the world. Injection molded with Tapered Lens Technology for optical precision and a high level of protection.
How do Smith's Interlock frames work?
Twist. Remove. Replace. It really is that simple. Interlock is the most intuitive and easy-to-use interchangeable sunglass lens system period. All it takes to engage our patented lens exchange system is a twist of the temple. Then, replace the lens with an alternate lens tint and twist the temple to close. That's it.

What is the Regulator Ventilation System?
The Regulator goggle has an adjustable ventilation system to control circulation. A sliding bar allows you to increase or reduce airflow during changing weather conditions. This is an ideal system for demanding skiers and contact lens wearers.
What is the Airflow Ventilation System?
Featured in our Airflow and select Junior Series models, our Airflow lens technology features vents in the brow of the lens that increase the circulation of fresh air to keep the inner lens dry and fog-free. A semi-porous foam filter is positioned behind the vents to prevent snow and moisture from infiltrating the goggle chamber.
Which Smith goggle is suited for helmets?
Smith offers many helmet compatible goggles, such as the I/O, Phenom, Prophecy, Heiress, Anthem, Stance, Scope Graphic, Scope Pro, Transit Graphic, Transit Pro, Cascade, Monashee, Cariboo, Gambler, Gambler Graphic, Sundance Kid, and all Turbo Fans
Do you have polarized lenses for Smith goggles?
Yes we do. Our Polarized Rose Copper lens is available in Black in the Phenom, Prophecy and Anthem and is also available as a replacement lens.
How do I clean my goggle lenses?
Do not use any paper products, including Kleenex. To clean the outside of the goggle you can breathe on the lens to create moisture, do not use any other liquids. Clean the outside with a soft micro fiber cloth such as Smith's Smudgebuster but this should not be used on the inside of the lens if it becomes wet or damp since it can cause scratches. If you need to clean the inside of your lens use a Smith Snow Eraser and dab your lens rather than wipe you lens, which can create scratches.
How do I control fogging of my Smith goggle lenses?
This comes down to the basics. Make sure your goggles form a tight seal on your face. Make sure to store them in a dry, warm, well ventilated area so they are sufficiently dried out after each use. Take proper care using lens cleaning kits and the Smith Snow Eraser & the Smith Smudgebuster.
What is the Fog-X coating?
This is a hydrophilic chemical treatment that creates a micro-etched surface on the inner lens to absorb moisture before fog can form. Because Fog-X is a treatment that is actually burned into the lens, it can't be wiped away like other anti-fog coatings.
What is that little filter in the corner of my Smith Goggle Lens?
This tiny filter is a revolutionary, micro-porous filter called Porex. Its composition is structured such that air molecules may pass through the filter while water molecules cannot. By utilizing this filter, the thermal lens is allowed to adjust to varying altitudes while preventing moisture from entering the space between the lenses. This is the world's strongest thermal lens barrier.
What is a Flexible Urethane Frame?
Smith uses a unique Urethane compound, which allows the frame to conform to individual facial features while maintaining its flexibility in extreme cold temperatures.
Why is the goggle strap connected to an outrigger?
A key element in goggle/helmet compatibility is this outrigger. The outriggers have been strategically positioned on the frame and engineered to transfer pressure evenly across the brow and nose for a complete seal. When used with a helmet, the strap articulation provides a comfortable and consistent goggle fit.
Do Smith Goggles use carbonic material?
Yes. Smith has set the standard in lens performance. All Turbo Fan, Spherical, and Regulator Series lenses feature a Carbonic-X outer lens. Each one is individually molded to offer optimum scratch and impact resistance, increased visual acuity and enhanced contrast sensitivity. The inner lens is impregnated with our Fog-X lens treatment for increased anti-fog performance. The Carbonic-X lens meets Class 1 optical standards as well as ANSI Z80.3 standards. There is simply no better lens.

What technology does Smith use for Helmet Ventilation?
Smith uses the AirEvac 2, AirEvac, the Regulator, & Airflow. AirEvac 2 maximizes goggle and helmet integration to alleviate goggle fogging and increased ventilation by allowing fog-causing moist air to evacuate from the goggle and helmet by channeling air across the user's head to exhaust it at the rear. Smith AirEvac chimney vents and under-shell vent channels actively pull hot air out of user's goggles to prevent fogging and increase ventilation. Adjustable, easy to use and extremely effective, our Regulator ventilation system allows you to control the amount of airflow and heat exhaust even with a gloved hand. You�ll thank us later. Airflow ventilation utilizes waterproof vent plugs for easy climate control in all conditions. Removal of vent plugs allows maximum airflow and heat exhaustion in warm temperatures. Installed vent plugs create a warm, dry seal from all mother nature can throw at you.
How do Smith's helmets create airflow?

Sunglasses Prescription Technology
What is O.D. & O.S.?
O.D. simply means right eye. It is the short form of the latin term oculus dextrus. O.S. simply means left eye. It is the short form of the latin term oculus sinister.
What is Sphere?
The number under the heading sphere is the main part of your prescription. The number itself denotes the strength of the lens as measured in diopters. A diopter is a unit of measurement that is simply the inverse of the focal distance of the lens as measured in meters. For example, if a lens has a strength of 2 diopters, then parallel light rays that pass through this lens will focus together at a distance of 1/2 meter (50 cm) away from the lens. The SMITH Spazio prescription program is available for sphere measurements from +2.00 to -5.00 diopters.
What is Cylinder?
If there is no value under the cylinder heading, then you have a very simple prescription. If there is a value under this heading, then you have astigmatism. Like sphere power, the cylinder power is also measured in diopters. The SMITH Spazio prescription program is available for cylinder measurements from +2.00 to -2.00 diopters.
What is Axis?
As mentioned above, a special cylindrical lens is needed in order to correct astigmatism. Not only does the strength of the cylindrical lens need to be specified, but the lens itself must be rotated into a specific position in order to provide the proper vision correction. The axis represents the amount of rotation of the cylindrical lens in degrees ranging from 1 to 180.
What is Prism?
This is a box on the prescription form that is rarely filled in. Occasionally, when the two eyes are not properly aligned and looking directly at the same thing, prism can be ground into the lenses in order to re-align them. This can occur with strabismus (an eye turn) or in situations where the eyes are properly aligned but are under a tremendous amount of strain in order to keep them aligned. The value under the prism heading denotes the strength of the prism.
What is Add / Progressive Lenses?
If there is a value under the add heading, then you have a bifocal (or Progressive) prescription. At this time, SMITH Spazio prescription lenses cannot be created with a progressive prescription. The engineers are hard at work and we will update as soon as their results are favorable.
What is Pupillary Distance (PD)?
The distance between the center of your pupils is known as the pupillary distance, or PD. Before your prescription lenses are cut, the pupillary distance needs to be measured. This measurement is then used so that the optical center of each lens can be lined up with your pupils in order to give optimal visual clarity.
