FREQUENTLY ASKED QUESTIONS

What exactly is the revolutionary new lens material in PeakVision Sports Performance Eyewear?
PeakVision Sports lenses are made of a new material called NXT, originally designed for military use in helicopters. There was a need for a material which was durable enough to withstand harsh conditions, but also distortion free so the pilots could accurately see the terrain. NXT offers optical clarity like that of glass found in the finest camera lenses. It is also shatterproof and incredibly lightweight.
Why doesn't PeakVision Sports use polycarbonate lenses like many other sunglass manufacturers?
Polycarbonate lenses are detrimental to the game of golf. The manufacturing process used to create the majority of plastic (polycarbonate) lenses in today’s sunglasses is 50 years old and produces lenses with significant birefringent optical distortion … sunglass haze. That’s why you can’t read the green (or your scorecard!) with most sunglasses. With PEAKS, you’re getting a read you can trust from the 1st tee to the 18th green.
Why is a Dual-Zone lens best for golf?
The science behind Dual-Zone lens technology is based on the principal that it is impossible for a single-tint sunglass lens to optimize your vision for both the bright sky and the relatively darker grass turf. When you take illumination measurements on the golf course with a digital light meter, the lighting extremes range from 82,732 LUX for the sky down to only 3,122 LUX for the grass turf, less than 4% of the ambient brightness in the sky. The typical single-tint amber lens is perfect for enlightened visualization of the putting surface and to enhance contrast sensitivity for improved green-reading...but the sky remains uncomfortably bright (62,440 LUX) and colors are distorted, which negatively affects distance perception. The typical single-tint gray lens reduces the brightness of the sky down to a visually comfortable 14,460 LUX. But the gray lens also reduces the illumination of the putting surface to a mere 1,195 LUX, far too dark for accurate green reading. PeakVision Sports’ Dual-Zone golf lens integrates a neutral-density (gray) filter in the Upper Zone to manage the glare and brightness in the sky and bring it down to a comfortable illumination of 14,640 LUX. The amber-tuned Lower Zone maintains the natural illumination of the turf at 3,036 LUX and increases contrast sensitivity for enhanced vision of the putting green. The Dual-Zone lens perfectly balances the light into the Ideal Range...whether you are looking up in the sky to track your ball in flight or looking down at the turf to read a green. Only PeakVision Sports’ Dual-Zone lens technology delivers the best of both worlds and complete protection for your eyes and vision. See Better, Play Bettter.
Where are the PeakVision sunglasses made?
All of the Dual-Zone lenses are created in Italy. Our frames come from quality factories around the world, but primarilyl in Italy and China.
How much do the PeakVision sunglasses cost?
MSRPs range between $139 - $249 depending on the frame style and $395 - $489 for prescription products. Compared to other high-end products on the market our glasses are very competitively priced. Only our eyewear offer greater value due to the vastly superior lens material and patented Dual-Zone filter.
How can I purchase PEAKS if I reside in Canada?
Our website is configured to only process orders within the United States. PeakVision Sports corporate office will be more than happy to assist you with purchasing PEAKS or finding a PEAKS retailer in your area. Please contact PeakVision Sports, 888.856.3419, for more information.
Why aren't PeakVision Sports' lenses polarized?
PeakVision Sports offers lenses that are polarized and are great around the water, but not our golf specific lenses. Polarization effectively limits the light rays that get to your eyes to only those coming from a very narrow angle, reducing your peripheral vision. Peripheral vision is critical to short shots around and on the green when you must see your ball, the line, and your target! Polarization can also negatively impact depth perception. Additionally, polarization offers no more UV protection than any other type of lens.
Why should I care about UV Protection for my eyes?
Casual golfers have twice the incidence of UV related eye diseases compared to the general population, avid golfers have 4-6 times the incidence and PGA Pros have 24 times the incidence. Harmful radiation can have long-term effects on your vision.

Additionally, eye fatigue and eye strain greatly affect your game, creating headaches, distorted vision and blurriness. A University of Utah Graduate student, Ron Kenneth Lord and Salt Lake City golf pro Henry White, conducted a study of 52 club professionals and found that 54% did not wear protective eyewear while they played and 51% had some form of sunlight-exposure disease. Forty-eight percent had indications of an ocular disease known as pterygia, a tissue mass that is often described as “growing over the eye” and obstructing vision. This is 400 percent more prevalent than in the general US population. PEAKS are like sunblock for your eyes, providing 100% UV 400 protection from A, B and C rays, without interfering with your performance on the course.

Are the frames adjustable?
Several of our frames have adjustable nose pieces, spring-loaded hinges and/or malleable temple ends.
What's the difference between the frame styles?
Each frame style is built for durability, weightless fit and ultimate visual performance. The main difference between frames is size and material. Some frames are better suited for small or slender face shapes, while others work best for larger or wider face shapes. Many frames come in multiple colors and several frames have adjustable nose pieces and spring-loaded hinges. The descriptions on the frames should address these issues.
Is one frame style more durable than another?
All of our frames are very durable. We rarely hear problems of breakage outside of random accidents. However, understanding that breakage can occur, we have a one-year warranty on the frames, and will replace or repair them as necessary.
What is the most popular frame?
There isn’t really a most popular style. It mainly depends on personal preference, face shape and head size.
Are there frames specifically for men and for women?
All of our frames are unisex, and work just as well on women as they do on men. Styles that tend to fit women the best are CL1, DG9, CH2, GR4 and SD7.
Are the lenses scratch proof?
The lenses are shatterproof and very scratch resistant. No lens material on the market is completely scratch proof, however the NXT material used in PEAKS is more scratch resistant than any polycarbonate lens.
Do you sell replacement lenses?
We do sell replacement lenses for our PEAKS models that have interchangeable lenses (CL1, CH2 and GR4). They are sold for $49.95.
Which lens offers the most coverage?
It really depends on the person’s face. All of our styles, if worn correctly, wrap around the eyes to reduce peripheral glare. Our largest lenses are in the frame styles SL8 and GR4.
Do you have other sport-specific lenses?
All of our frames have the Dual-Zone lens technology. We are now selling sunglasses and lenses tuned for specific sports including hunting, shooting, baseball, snow sports, cycling, and running.
Are PEAKS available in prescription lenses?
PeakVision Sports is proud to be working with authorized Eye Care Professionals and leading national optical laboratories to produce PeakVision Sports patented Dual-Zone lenses in prescription. We offer prescription PEAKS in four of our models (SD7, SL8, ZQ5 and EL0). Due to the complexity of preparing prescription lenses, PEAKS Rx will only be offered through our headquarters and through retailers who are Eye Care Practitioners (ECPs). To locate an ECP near you please search under Store Locator. All ECPs will be identified as an authorized prescription retailer.
Does the performance of the Dual-Zone lens technology change with the weather conditions or time of day?
Because of the Dual-Zone filters in the lenses, our glasses can be worn in all lighting conditions, from bright sunlight to overcast days.
Can PEAKS be worn for outdoor activities beyond golf?
Our glasses are made specifically for improving your golf game, but they are not just for golf. They can be used in day-to-day outdoor activities and are actually great for driving vehicles.
What accessories are available?
At this time, each pair of PEAKS comes with a protective zippered case and a micro fiber cleaning cloth that doubles as a soft storage bag. You can also purchase replacement lenses, personalized logo cases, hats, shirts, golf bags and more.
