  • Lenses

    • How does ChromaPop work?
    • What is the difference between ChromaPop and ChromaPop Plus?
    • Do you have a ChromaPop lens that is non-polarized?
    • 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.
    • 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.
    • 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.
    • 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.
    • 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.
    • Do you have polarized lenses for sunglasses with interchangable lenses?
      Yes. Smith offers Polarized lenses in a variety of tints. Check out our Replacement Lenses for your model.
    • 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 hydroleophobic coating on your Smith sunglasses help?
      The hydroleophobic 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.
    • What is Smith Techlite Glass?
      Our Techlite Glass Polarized lenses are made in Italy and offer 20% weight reduction over traditional glass and a 6x-improved scratch resistance.
    • What is CR39?
      CR39 is a lightweight advanced polymer that has a high abrasion and scratch resistance. Fashion forward colorations and gradient fades compliment excellent optical clarity.
    • Do you have a brief description of each lens tint?
      A brief description of each lens tint is available on each product page, click the "Show Lens Info" button to the lower left of the product image. All lenses provide 100% UVA/B/C protection and TLT Optics. Please refer to the Sunglass Replacement Lens Page.
    • What conditions are best suited for each lens?
      For the most part, ideal lens tint selection is based on personal preference and current lighting conditions. With ChromaPop technology you can select a tint based on Visible Light Transmission (VLT) or how dark or light your lens preference while mainting visual performance. See our lens selector for more information.
    • What base curves do Smith sunglasses use?
      The base curve is the radius of the sphere measured from the back of the lens. Smith features styles with 6, 8, and 9 base lens curvature. Models that include 6 base tend to be flatter, while 9 base styles provide the maximum amount of wrap around your face. The higher the number, the more "wrap" the sunglasses will have.
  • Prescription

    • How long is a prescription good for?
      Most prescriptions are good for a duration of two years.
    • What is O.D. and 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.
    • 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 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.
    • Do we offer ChromaPop in prescription?
      Yes, we have selected frames that are prescription approved and can be made in prescription ChromaPop. You can view the frames that are approved for prescription here.
    • Do you offer prescription bifocal lenses?
      We offer lined bifocal prescription lenses in four selected frames. The frames we offer the bifocal lenses in are the Dolen, Drake, Wolcott and Wayward. These are lined bifocal lenses; we do not offer progressive (no line bifocals) at this time. These lenses are only available in polar chromic copper, polar chromic amber, polar chromic gray and polarized brown.
    • Will Smith convert my sunglasses to prescription lenses?
      Once you have purchased a pair of sunglasses we will not be able to insert prescription lenses unless they are part of our Interchangeable Rx series. In order to ensure the highest product quality, we must start with a frame that has never had lenses installed. Some opticians will provide this service if your prescription is between +1.00 to -2.50 and they have the technical capability to use highly wrapped 8 base lenses. The best long-term option is to start with a brand new pair to ensure correct optical correction and durability.
  • Care

    • 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. You can use a sunglass specific lens cleaning solution along with the microfiber cloth.
    • 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 the Smith Cleaning Kit and dab your lens rather than wipe your lens, which can create scratches.
    • How do I control fogging of my Smith goggle lenses?
      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 - do not keep them inside your helmet until completely dry. Clean with care.
    • When should I change the Turbo Fan batteries?
      Tests were conducted in extreme conditions and the Turbo Fan fan (with fresh AAA batteries) ran at least 50 hours (The fan uses very little power - as long as you remember to turn it off before you go to bed).
    • What is the Turbo Fan?
      Patented micro-electronic fan in the Turbo Fan Series. Turn the fan on when you get to the hill and in the low setting, the Turbo Fan system will run continuously all day long to exhaust moisture from inside the goggle.

      A handmade acetate frame involves a 33-step handcrafted process that features the inclusion of wire-core temples for a customizable fit. A huge variety of rich color combinations that possess depth and have a distinct character are made possible with this material.
    • What is hydrophilic megol?
      Placed at the nose and on the temple tips, this material gently grips your skin to help keep your frame in place. The gripping power increases when introduced to moisture.
    • What are AutoLock hinges?
      AutoLock hinges are uniquely engineered to hold or lock the temples in the 'open' position making it easier to put the frame on your face with one hand.
  • Goggles

    • How do I change the lenses on my goggles?
      If you have an I/O or interchangeable series goggle, follow the instructions included with the product or follow this link. If you have a full-frame goggle follow these Instructions:
      1) Carefully remove the old lens by separating the frame from the lens.
      2) Begin at the top and work around the perimeter of the frame.
      3) When installing the new lens, start with the nose and work around the sides until you get to the top.
    • What if my Smith strap is not long enough for my helmet?
      Smith sells the Helmet Helper, an attachment that lengthens the clip buckle strap for helmet compatibility.
    • Do Smith Goggle lenses use TLT?
      Yes. All Smith Goggles use Tapered Lens Technology (TLT) to give you distortion free vision. Objects in lens are exactly the same as they appear. When light passes through a medium it refracts or changes course. Smith lenses with TLT allow you to see with 100% accuracy and maximum comfort.
    • Which Smith goggles are compatible with eyeglasses?
      Smith offers many goggles with enlarged lens chambers that easily fit over most eyeglasses, some of which are available with an integrated ventilation fan. In addition, they are built with performance face foam and a split v nose to eliminate eyeglass temple pressure. The current OTG models are: I/OX, Prophecy, Phenom, Knowledge, and Showcase.
    • What is the Turbo Fan?
      Patented micro-electronic fan in the Turbo Fan Series. Turn the fan on when you get to the hill and in the low setting, the Turbo Fan system will run continuously all day long to exhaust moisture from inside the goggle. The high setting can be used to quickly exhaust moisture in extreme conditions. On the low setting the Turbo Fan system can run continuously for up to 50 hours on one AAA battery.
    • Do you carry goggles that are designed for a female face?
      Yes. The IO/S, Virtue, Riot, Showcase and Range are all designed as a small or Women's Specific Fit. They are anatomically engineered to work in unison with female facial features.
    • What is the Airflow Ventilation System?
      Featured in our Airflow 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?
      All Smith goggles are designed for Ultimate Integration with Smith helmets. Fit and ventilation are integrated to create a complete system of vision and protection.
    • What is the Fog-X coating?
      Fog-X is not a coating, it 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.
  • Helmets

    • What are the types of helmet constructions that Smith offers?
      Smith offers three main types of helmet constructions: Hybrid Shell Technology, In-Mold Construction, & Bombshell Construction. Smith's new revolutionary Hybrid Construction Technology uses separate lightweight and durable shells merge to create an entirely new helmet category. Hybrid construction fuses two proven technologies by combing a tough ABS upper shell with a flyweight in-mold liner into a sleek, low profile, and modern design. Hybrid construction also creates a clean smooth top surface by enabling the low profile Regulator to function with reduced mass and volume. The performance standard for many years, In-Mold construction creates a lightweight helmet with an EPS liner to maximize protection, comfort, and value. Just like in goggles, our mid-range product includes features found in the competitors' top models. Lastly, Bombshell Construction-Injection molded ABS shells withstand high-impacts and offer unparalleled durability. For when you need your helmet to be as tough as your truck, Bombshell delivers.
    • What technology does Smith use for Helmet Ventilation?
      AirEvac ventilation maximizes goggle and helmet integration to alleviate goggle fogging and increase 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 provides constant exhaust through fixed vents located strategically within the helmet.
    • How does Smith's AirEvac technology help with ventilation?
      AirEvac utilizes shell vents as well as internal EPS channels to increase airflow ane evacuate warm, moist air to prevent goggle fogging. Cool, dry air is consistently pulled into the goggle as the warm, most air is exhausted over the wearer's head and out the rear of the helmet.
    • What types of linings are used in Smith's Helmets?
      Smith uses X-Static Lining or a plush fleece Tricot to provide you with the best comfort. The X-Static Lining is a silver coated textile fiber that enhances products with permanent and natural anti-odor, anti-static and thermodynamic properties. The Tricot linings are long brushed fleece for additional comfort and warmth, available in women's and junior helmet models.
    • What is the Helmet Dial Fit System (DFS)?
      Great helmets start with a great fit. Smith's proven ergonomic head form combined with our Helmet Fit System (HFS) provides exceptional performance and comfort. The soft, flexible plate and liner system of the HFS contact the back of the head when tightened for a proper fit. The self-centering system utilizes an intuitive rotating dial. Vertical adjustment is available with three position options located at the back/center attachment point. To raise or lower the DFS, detach it from the snap basked fixed within the EPS material and position up or down to accommodate your fit and comfort needs.
