Step 6: Select your Coatings


Step 1:  Have your eye prescription ready

Make sure it is not more than 2 years old. If you really want to know what SPH, CYL, Axis, Prism, and PD means, please click here to learn how to read your prescription. If your PD (pupilar distance) is not listed, click here to determine how to measure PD.


Step 2: Choose the right frame

Wearing casual eyeglasses or sunglasses on a motorcycle can be extremely dangerous. Casual glasses do not seal out wind or debris and can easily fly off when you turn your head. If you wear a full-face helmet, then you probably do not need sunglasses with foam padding. If you wear a half helmet or no helmet, then you should definitely consider sunglasses with foam cushion. Choose a frame that wrap around your face, provides 180-degree protection and can withstand a harsh impact. All Wiley X, BikerArmour, and 7eye motorcycle eyewear are specifically designed for motorcycle riding. If you are unsure which frames will fit, we can send you 8 – 12 frames to try on with our FREE Try Before You Buy Program.


Step 3: Choose Lens Type

Standard or Traditional Single Vision Lenses: Single Vision Lenses have the same vision correction over the entire lens. Standard Lenses are primarily used for casual frames with flatter lenses. BikerShades always recommends digital free form lenses for best optics; however, standard lenses are acceptable for wrap frames up to +/- 2.50 on the Sphere. 

Premium Digital  Free Form Single Vision Lenses, (Biker Recommended):  Also known as High Definition or Free Form Lenses, Digital Lenses are specifically designed for base 6 to 8 curvature lenses, common in high wrap frames. Digital lenses take into consideration how the frames are actually shaped and how they fit. Unlike “casual” frames, high wrap frames possess the following three differences: a more aggressive frame wrap, higher degree of frame tilt, and a shorter distance from the eye to the lens. Without compensating for these three differences, the Rx lens may result in unwanted astigmatism, causing blurry vision, dizziness, and loss of peripheral vision.

Digital lenses are optimized with computer-controlled surfacing equipment that is much more precise than conventional tools. Digital lenses are surfaced in power increments of 0.01 diopter (D), compared with 0.125 to 0.25 D increments with conventional tooling. Therefore, digital lenses deliver superior clarity for each unique prescription for exceptional performance for single vision lens wearers.

Digital Free Form Progressive Lenses:BikerShades only offers premium DIGITAL progressive lenses. If you are shopping around, make sure to ask if the lenses are digital before you purchase! If you are currently wearing bifocals, have difficulty reading small print, or have an “Add Power” listed on your prescription, you may need progressive lenses. Please note that you are not required to wear progressives or bifocals if you will not be using your glasses to read maps or menus. Unlike bifocals, progressives offer an even transition from distance to near vision, allowing the wearer to view all intermediate distances.They restore clear and accurate vision at all distances, without the need to change glasses constantly.

FT 28 Bifocals: Unlike progressives, Bifocal lenses have a noticeable line that separates the top area, which is for distance vision, and the bottom area, which is for reading. The “28” refers to the width of the bifocal area, and is the most common size compared to FT 35. You are not required to wear bifocals if you will not be using your motorcycle glasses to read maps or menus. In addition, if you are less than 40 years old, chances are you do not need bifocals or progressives.


Step 4: Choosing your lens material 

Polycarbonate: Polycarbonate is a tough, versatile polymer used for bulletproof windows, helmet visors, and compact discs (CDs). If you have ever tried to break a CD, you know how tough polycarbonate can be! Normally polycarbonate is an added upgrade, but BikerShades includes polycarbonate without additional charge! The advantages of polycarbonate include:

1. Polycarbonate offers 100% UV protection, plastic lenses do not.
2.  Highly impact resistant and extremely lightweight. See video below.
3.  Polycarbonate lenses are about 10 percent thinner than Trivex and plastic, both due to a higher index of refraction.
4.  Excellent transparency and high refractive index (it can bend light to a higher degree than glass or plastic of equal thickness). 

Trivex (Biker Recommended): Trivex lenses offer superior optics and impact resistance compared to any other lens material. Advantages of Trivex include:

1.  Trivex offers 100% UV400 protection, plastic lenses do not.
2.  Trivex is the most impact resistant material available. See video below.
3.  Trivex is the closest in clarity to glass - the clearest material on earth.
4. Higher Optical Clarity (center): Trivex lenses have less internal stress, which results in sharper central vision than polycarbonate lenses.
5. Higher Optical Clarity (peripheral): Trivex lenses have a higher Abbe value which results in sharper peripheral vision and less chromatic aberration than polycarbonate.
6.  Trivex lenses are about 10 percent lighter than polycarbonate lenses.
7.  Compared to polycarbonate lenses, Trivex lenses offers clearer and crisper optics. 



Step 5: Choose Transitions, Polarized or Solid Tints



Transitions Signature w/ Chromea™ 7 technology NEW!: Most responsive Transition lens, so they change much faster when lighting conditions change like riding in and out of tunnels, riding in shadows, riding towards or away from the sun, or walking indoors or outdoors. 

   Available in Clear to Smoke, Clear to Brown and Clear to Graphite Green (NEW!) 

     · Lenses fade back to clear the fastest when going indoors.
     · Lenses darken the fastest when going outdoors.
     · More reactive to UV light, so the lenses get darker in shadows or partially sunny conditions.
     · More responsive to reflected light, so they also adapt to light reflected from windows, cars, and water.

Transitions XTRActive (Biker Recommended): Latest Transitions Lenses that gets darker than any Transitions lens on the market. Advantages include:

· Darkest Transitions on the market today.
· Change from clear to a very dark smoke, as dark as your daily sunglasses.
· Darkens behind the windshield of a car

Transitions® Vantage™ Revolutionary Lenses with variable polarization: Offers polarization that increases as the lenses get darker in outdoor light. So as the lenses get darker, vision gets crisper, sharper, and more vivid while glare is reduced in even the brightest outdoor conditions.

Polarized: Eliminates glare off shiny surfaces such as chrome, water, mirrors, etc. Clarifies and sharpens vision. Once popular only with fishermen, polarized glasses also benefit bikers, golfers and anyone who drives. Polarized lenses offer a clearer view by reducing glare from flat reflective surfaces such as the lake or the hood of a car.

As sunlight bounces off a horizontal surface such as the road or hood of car, the reflected light travels in a horizontal direction rather than being scattered in all directions. Sunlight bouncing off a horizontal surface creates an annoying and perhaps dangerous intensity of light, which we refer to as glare; Polarized lenses contain microscopic vertical stripes on the surface of the lens, which filters out the horizontal rays, or glare.

Solid Tints:

Dark Smoke: Good for general-purpose use. They are dark enough to provide overall protection with true color perception, and reduce glare, especially off water. Good for driving, baseball, tennis, football, soccer, water sports, and all other outdoor activities. Great variable weather tint for sunny or overcast days.

Dark Brown: Improves contrast and contains a red element to enhance depth perception. Excellent for golf, tennis, high-altitude sports, fishing, boating/sailing, or any sport where distance needs to be judged. Can be used for partly cloudy to sunny conditions.

G-15 Smoke/Green: Emphasizes colors our eyes see most easily (green and yellow) and de-emphasizes less noticeable colors (red and blue). The G-15 lens absorbs 85% of visible light, and transmits only 15%. The G-15 lens results in more natural vision - true colors that are easy on the eye. 

Copper HD: Improves contrast and contains a red element to enhance depth perception. Good for golf, tennis, high-altitude sports, fishing, boating/sailing, or any sport where distance needs to be judged. Can be used for partly cloudy to sunny conditions

Yellow: Provides greater clarity in fog, haze, and other low-light conditions and filters out blue light that can make focusing difficult. Good for skiing, mountain biking, hunting, aviation, tennis, and target shooting. Good from dawn until dusk. Also good in foggy or hazy conditions.

Clear: Great for night riding. When combined with an anti-reflective coating offers the ultimate night riding experience by drastically reducing the halo effect around lights at night.

Green (other): Transmits all colors evenly. Good for general-purpose use and dims glare while brightening shadows. It is good for all outdoor activities and can be used rain or shine.

Blue (other): Fashionable and cosmetically appealing. Reduces glare, helps to see contours, and improves color perception. Can be used for spectator sports and golf. Good in misty, foggy, and snowy conditions

Rose (other): Enhances visual depth and provides good road visibility. Helps adjust contrast, comforting the eyes, so it reduces eye strain. Can be used for cycling or racing. Good in most weather conditions, especially in snow.


Step 6: Select your coatings

Anti Reflective (AR) Coating: AR coatings block reflected light, which results in a reduction in glare, annoying reflections and halos around lights at night. They reduce the glare that you see, as well as the glare that others can see on your lenses, so your eyes are more visible to others.

      Classic A/R Includes:
       Anti-Reflective Coat
       Standard front side scratch coat
     Elite A/R includes:
       Anti-Reflective Coat
       Front and back side scratch coat
       Hydrophobic Coat and Oleophobic Coat
       Extreme scratch coat, which outperforms glass. 

Scratch Coating: Provides additional scratch protection for your lenses. 

Anti Fog Coating: Optifog technology is guaranteed to prevent blinding fog on lenses, making it much safer to ride. It is a permanent anti- fog solution and is thermally baked on the surface of the lens. Includes activation cloths, which must be used while cleaning the lenses to activate the anti-fog properties. 

Mirror Coating: highly reflective coatings applied to the front surface of lenses. Mirror coated lenses reduce an additional 10% - 60% of light entering the eye. This makes them especially beneficial for activities in very bright conditions. The color of a mirror coating is a purely cosmetic decision. Here are the mirror coatings we offer.
