      No, the Smith Focus app is only available on devices using the Apple and Android Operating Systems.
      On your mobile device or tablet, go to the Apple App Store or Google Play store and search for "Smith Focus” app. When you find the app, click "download" to install it.
    • Is Lowdown Focus safe?
      In order to make Lowdown Focus wireless, data is transmitted via Bluetooth, which is no different from other portable Bluetooth devices such as wireless headphones. Cell phones actually emit far greater electromagnetic radiation than Bluetooth.
      The location of our Bluetooth antenna in Lowdown Focus is on the outward facing side of the circuit board, so the signals are directed away from the user's head. Lowdown Focus uses Bluetooth 4 Low Energy (BTLE) and complies with all of the regulations for Bluetooth device sales. The output is far less than the emissions of a standard cell phone signal.
    • Does Lowdown Focus interfere with my pacemaker?
      At this time Lowdown Focus is not a certified medical device and we have not tested it extensively with pacemakers.
      However, we don't believe Lowdown Focus will affect the pacemaker, because it does not have enough power. No electromagnetic energy is emitted by the Lowdown Focus; instead, it uses passive electrodes to measure the brain's natural electrical activity.
      Lowdown Focus connects to a smartphone using Bluetooth. According to the American Heart Association (AHA), Bluetooth devices are safe.
      Please refer to the AHA website for more details.
      There have been rare instances where Pacemakers have affected the Lowdown Focus signal quality. If you are using a Pacemaker and have encountered issues during the Signal Quality check, please reach out to smith@smithoptics.com.

    • What are the terms of Lowdown Focus warranty?
      Please refer to our Warranty page here.
    • What is Lowdown Focus measuring?
      Lowdown Focus detects a full range of brainwave activity. Brainwaves are typically broken up into five bands and Lowdown Focus is capable of detecting all five bands. The five bands are:

      Delta waves which are most present during deep sleep.
      Theta waves which are associated with drowsiness, light sleep, and visualization.
      Alpha waves which occur during wakeful relaxation.
      Beta waves which occur when alert, actively thinking or problem-solving.
      Gamma waves which occur when involved in higher mental activity and consolidation of information.


      In creating the Smith Focus app, we started from these brainwaves and then spent years doing intensive research on higher-order combinations of primary, secondary and tertiary characteristics of raw EEG data and how they interact with focused-attention meditation.
      Your brain is constantly generating electrical signals when you’re thinking, sleeping or even relaxing. These signals can be detected from outside your head, via sensors.
      Lowdown Focus uses the same brain sensing technology that doctors and scientists have employed for more than a century to detect your brain signals, similar to how a heart monitor measures your pulse. Lowdown Focus then sends that feedback to your smartphone or tablet using your Bluetooth connection.
    • Can I see my raw brainwaves with Lowdown Focus?
      Lowdown Focus sends raw brainwaves via Bluetooth which can be received by various applications. However, The Lowdown Focus mobile app does not show raw brainwave data.
    • Is Lowdown Focus useful for athletes only?
      Lowdown Focus can be useful for anyone from athletes to those looking to train their focus and improve their ability to navigate through the chaos of everyday life.
    • Can I use Lowdown Focus outside of mental training?

    • What are the benefits of using Lowdown Focus for meditation?
      Lowdown Focus is designed to help novices learn to meditate and form the habit of a regular and rewarding practice. You get accurate, real-time feedback on what’s happening in your brain while you meditate. It teaches you the essentials of meditation and provides milestones and rewards which motivate you to commit to a daily meditation practice.
      Science has shown us that meditation leads to clearly visible changes in the brain. Lowdown Focus lets you experience those benefits with none of the uncertainty associated with traditional meditation practices.

      WHAT ARE THE BENEFITS OF MEDITATION WITH LOWDOWN FOCUS?
      Meditation has been extensively validated by leading neuroscientists for improving brain health
      Meditation is as effective as anti-depressant medication like SSRIs in treating depression
      Meditation is the most effective treatment for post-traumatic stress disorder and is widely deployed with veterans and in psychology practice
      Meditation literally changes the structure of the brain, and the brains of meditators are anatomically 7.5 years younger than non-meditators at 50 years old
      Lowdown Focus solves the common problem of adherence to practice by making meditation easy

      I MEDITATE ALREADY, HOW CAN LOWDOWN FOCUS HELP?
      Whether you are an occasional meditator or someone with no trouble keeping up the habit, you know more than most how important it is to keep engaged with your practice. Lowdown Focus offers you a glimpse into your brain's activity while you meditate and offers a completely different way of engaging with your practice as you explore how your brain responds to each session.
      As an experienced meditator, you might find that certain aspects of the real-time feedback geared toward beginners are more of a distraction than a support. By tapping the volume icon in the corner of the screen, you can adjust the volume of each feedback element and find the levels that work for you. Even if you were to turn the real-time feedback completely off, you'll still gather an immense amount of insight and motivation when you review your brain data after each session.
    • Can I use my Lowdown Focus with multiple devices?
      Absolutely. You can log into your account and continue your training with any Lowdown Focus and a compatible mobile device or tablet. Make sure you have a working internet connection or mobile network are connected to a mobile net on each device or sessions/progress may not appear across devices.
    • My Lowdown Focus won't connect via Bluetooth. What should I do?
      The Lowdown Focus DOES NOT need to pair with your mobile device or tablet's Bluetooth settings; Lowdown Focus pairs directly with the Smith Focus app. Just enable Bluetooth and enter the app.
      If you are using an Android device or tablet, please ensure your Location service is enabled. Unfortunately, Google's recent updates to Android require Bluetooth LE devices to access a user's location. This change forces us to ask for location permissions in the Smith Focus app. For more information please see "Why does the Android app ask for my location?" below.
    • I am having trouble getting good fit and signal quality. What do I do?
      Before each calibration and each session, Lowdown Focus checks to see if your glasses are turned on and getting a good signal using a multi-colored circle. This step is designed to prevent you from starting a session which will be unresponsive and unpredictable due to an improper fit.
      Whether you're having trouble getting the colors to fill in or your sessions are being interrupted with signal quality problems, there are a few things you can try to find a fit that works for you.

      Lowdown Focus is a sensitive device and requires good contact with your skin to detect your brain signals. To ensure a good connection, try the following:
      1. Ensure your Lowdown Focus is fully charged. For information about charging please see "Which charger can I use to charge the battery of my Lowdown Focus?”
      2. Tap the bottom of the signal quality check screen and swipe through and make sure you have followed each of the instructions there.
      3. Lowdown Focus mediation sessions are designed to be used while sitting still in a comfortable upright position. We cannot guarantee good signal quality or an accurate experience if you are lying down, in motion, or in any position other than still and upright.
      4. Try wearing the glasses in advance; put the glasses on while on the pair Sunglasses screen in the app. That way the signal will settle while you’re getting comfortable and starting your session.
      5. If you require a tighter fit, the ear sensors can be gently adjusted flexing them inward. Find a sweet spot where you can feel the sensors putting a comfortable amount of pressure against your skin, but not too much pressure.
      6. If it still doesn't work, try dabbing a touch of water on your nose or the tops of your ears depending on which section you are having trouble connecting with.
      7. Make sure your skin is clean and the headband is clean where the sensors make contact with your skin. Make-up, or the buildup of natural oils of your skin, can form a barrier that blocks the electrical signals from reaching the sensors. Try wiping your nose or ears with a damp cloth.
      8. Make sure there's no hair between the ear sensors and the tops of your ears.
      9. Keep your eyes closed and relaxed during your calibration to avoid unwanted interference.
      Even after you get the colors filled in, we recommend making a continued effort for the best fit possible. The better signal quality you have, the more accurate and responsive Lowdown Focus will be.
      If you are a regular user, cleaning your Lowdown Focus can help. Please see "How do I care for my Lowdown Focus?"

    • Why does the Android app ask for my location?
      We take data privacy very seriously. Unfortunately, Google's updates to Android require Bluetooth LE devices to access a user's location. This change forces us to ask for location permissions in the Smith Focus app.
      However, we do not use this data for anything other than to satisfy Android's requirements for Bluetooth devices.
      To enable this please access your "Settings" icon (the gear icon) on your Android device or tablet. Please search the word "Location" and tap on it to enable it.
      Please do not turn off Location services as it will block the headband from connecting.
    • Can I create multiple user accounts with one Lowdown Focus?
      There is no limit for the amount of users that can use one Lowdown Focus. Each user would just have to set up individual accounts in the Smith Focus app on their mobile devices or tablets.
      If you are using one mobile device or tablet, each user would just need to sign into/out of their Smith Focus account before using Lowdown Focus. To sign out of the app click on the “Settings” tab and tap on “Sign Out”.
      The reasoning for setting up multiple accounts is that one singular account used by multiple people would cause the brain model to be off and skew each person's results.
    • Does Lowdown Focus read my thoughts?
      No, Lowdown Focus does not read your thoughts.
    • Is Lowdown Focus measuring my brainwaves all day long?

      Lowdown Focus is currently available for sale only in the United States and Canada.
    • Is the calibration necessary each time?
      Yes, Lowdown Focus must calibrate before each session to ensure it's receiving good quality signals from your brain to ensure that the app can provide accurate data and feedback.
    • Is the calibration necessary each time?
      Yes, Lowdown Focus must calibrate before each session to ensure it's receiving good quality signals from your brain to ensure that the app can provide accurate data and feedback.
    • What does my session data mean?
      In your session data after a meditation, the times for focused and unfocused represent the proportion of time spent in each state during the session.
      Lowdown Focus measures your brain’s natural electric field from outside your head while you meditate. At the end of your session, you are presented with a graph that presents these data in a way that helps you reflect on that session. The graph divides your session into three regions:

      Unfocused: This is time spent with a wandering mind. Your attention was fluctuating. Whenever you notice your active mind and bring your attention back to the breath, you are awarded with a recovery

      Neutral: This is your natural resting state. Your attention isn't fluctuating, but you aren't deeply focused either

      Focused: A deep restful focus on your breath. These are moments when you're truly concentrated on your breath. If you're calm for long enough, you'll hear birds.

      Birds: When you find a deep, restful focus on your breath for an extended period of time, you'll start to hear birds singing. Don't worry, this is part of the process! Over time, you'll learn to use the birds as a cue to settle even more deeply into focused attention.

      Recoveries: Whenever you notice your mind wandering and bring your attention back, you are awarded with a recovery. Recoveries celebrate the moment when your mind traverses from unfocused (wandering mind / fluctuating attention) to neutral (a natural state of rest). These are key to building the skill of focused attention and integrating the benefits of meditation into your daily life. Orange stars on your session graph display the exact moments where you recovered your attention.
      Experience Points (XP) are accumulated for every second you complete in a mediation session. 2 points per for every second while meditating with the Lowdown Focus sunglasses and 1 point per second for without using the glasses.
    • Can I use Lowdown Focus offline?
      You can only meditate with the Smith Focus app offline using accounts that have already been downloaded. When you're offline, you cannot access the Smith Focus database, which means you will not be able to create a new account or access accounts that don't already exist on your device.
      If you want to use Smith Focus app offline, make sure to first sign in when you're online. The account will then be downloaded to your device. From then on, you will be able to continue using that account on that device, including signing out and back in, when you're offline.
      Note that when using the app offline, recent changes to your account may not be synchronized. Your session history and any other account changes may not be up to date if you've been using other devices. Data from sessions you complete offline will not sync with our database until the next time you go online with that device and launch the app.
    • What does Lowdown Focus teach?
      The Smith Focus app's guided exercises help you discover how the app’s real-time audio feedback assists you in learning focused-attention meditation using the breath as a focus point. This scientifically-validated technique is great for beginners and included as a starting point in many different traditions.
      The app’s introductory courses cover different techniques and exercises that help you build a consistent practice with Lowdown Focus.
      The first course, “Get started with Focus”, provides 14 lessons which teaches you how to use your Lowdown Focus glasses and the tools we’ve built into the Smith Focus app.
      The second course, “Continue down the road”, has 8 lessons which teach you breath awareness, the foundation of your cognitive training routine.
      The third course “Next steps”, builds on the foundations learned providing new techniques to extend your practice.
      The introductory courses offer guided exercise which help you explore different breathing exercises and find the one that works for you.

    • What does Lowdown Focus teach?
      Smith Focus’ soundscapes provide you with real-time audio feedback on the state of your brain to help guide your meditation practice.
      Our relationship to specific sounds can influence how we feel during a session. This is why the app has different soundscapes for you to choose from. Try doing a few sessions in each soundscape to find one that works for you.
      You can also tap the volume icon during your sessions to personalize the soundscape. Each soundscape is made up of three different types of sounds:
      Weather feedback: changes in real-time based on the current state of your brain. You'll want to find a soundscape and volume setting where this sound supports your practice by helping you notice when your mind has wandered without interrupting you when you're focused. Note that the beach, rainforest, and desert stay true to the "weather" metaphor for the mind, but other soundscapes offer more abstract experiences.
      Background: this is a static, continuous sound that plays throughout your session. It can be useful to mask background noise in your environment and help make the soundscape feel more uniform. Sometimes reaching a calm state leaves a noticeable silence in the audio feedback which serves as its own distraction. Turning up the background sounds can help mask this effect.
      Birds: When you find a deep, restful focus on your breath for an extended period of time, you may hear birds singing quietly. Over time, you’ll learn to use the birds as a cue to settle even more deeply into focused attention.
      The volume in the Smith Focus app can also be adjusted when you start a session. Tapping on “Volume Settings” will display options to adjust the volume of several different components of the app.
      There are 4 different Volume settings:
      Feedback – Real-time feedback on your brain signals
      Birds – Birds land nearby when you’re calm for at least 5 seconds
      Background – Static background sounds for each environment
      Voice – Verbal instructions for calibration and exercises
    • Can I have a meditation session with Lowdown Focus while I'm doing sport activities?
      No. We recommend doing meditation sessions before and after sport activities.
      It is important to do your meditation session in a calm, comfortable position. Lowdown Focus is a sensitive device and will pick up even the small electrical activity from muscles around the eyes, jaw clenches, and also the brainwaves from visual processing, so ensure that you keep your eyes closed lightly when using it.
    • How does Lowdown Focus know whether my mind is distracted or focused?
      Lowdown Focus passively measures your brain’s natural electric field from outside your head while you meditate. When your mind is in a deep restful focus on breath, your brain will transmit more energy at certain brain frequencies, and less energy at others. When your mind is at a neutral state of rest, that pattern will change. When your mind wanders and becomes more active, Lowdown Focus will pick up a different characteristic energy pattern from your brain, which reflects your changing state.
      Our app translates your brain signals into a rich, real-time audio experience on your mobile device to help guide your meditation. A “focused” mind will hear the sounds of a tranquil environment. An “unfocused” mind will hear the weather soundscape change.

  • 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?

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.

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.

    • 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.
