SportRx Frame Width™ 
142mm
142mmSportRx Frame Width™ (SFW) is the measurement our Sports Opticians use to find the most accurate fit possible. Unlike most eyewear measurements that have little to do with fit, SFW serves as an indicator for how well a frame or goggle will fit your face.

*All Sizes in MillimetersDETERMINING YOUR SFW
Use Eyeglasses and Not Sunglasses
Using flatter eyeglasses makes for a more accurate measurement. It takes a bit more finesse with wrapped sunglasses to get an accurate SFW measurement.
Have more than one pair?It never hurts to have more than one 'frame' of reference! If you have more than one pair that you love, you can measure multiple pairs and get an average.
Make sure the glasses fit!
Since we're using your glasses as a template for ideal fit, make sure they're a pair that are comfortable: not too wide, not too narrow. A quick glance in the mirror will show if the frames spread too far past the edges of your face or seem to 'pinch' it.
How/What do I measure?Measure with the temples opened out fully. Aim for right behind the hinge and measure from the inside of the frame material of one side to the inside of the other side.
FINDING YOUR BRIDGE FIT
Finding the right eyewear for your face means two things: the right frame size and the right bridge style. At SportRx, we have three different bridge styles:
Standard
A standard nose bridge is best for those with nose bridges that go higher than their pupils, or if you have more narrow cheekbones. Standard nose bridges are fixed and don’t include adjustable nose pads.
AdjustableAn adjustable nose bridge includes flexible nose pads that can be adjusted for a firm, yet comfortable hold. This style is best for those who prefer a more customizable fit.
Low-Bridge
The low-bridge fit is designed for those with narrow nose bridges or cheekbones higher than their nose bridge. Also called Asian Fit, this is a great choice if your frames tend to slide down or touch your cheeks.
Indulge in timeless style with the Serengeti Ansel sunglasses, a classic double-bridge aviator design perfect for any occasion, formal or informal. The triple-layered metal rim not only adds stylish flair but reinforces durability. The adjustable rubber nosepads ensure a customized, comfortable fit for various nose bridge types, making this frame as versatile as it is stylish. Experience unparalleled clarity through Serengeti Trivex or mineral glass lenses, offering both optical excellence and the option for prescription. Serengeti Ansel sunglasses are an essential accessory for those who appreciate both style and functionality.

Serengeti Mineral LensesSerengeti is the only brand offering a 3-in-1 mineral lens technology, allowing you to experience the world at its most aspirational.
Serengeti Mineral Lens Technology
Serengeti ensures top visual acuity and eye protection by meticulously selecting and checking all materials and components used in their lenses. Their ultra-light mineral lenses, made from recyclable borosilicate optical glass, offer unmatched protection and visual experience while reducing environmental impact. These lenses are thinner and lighter, photochromic, scratch-resistant, and feature anti-reflective coatings to eliminate glare.
The Ultimate High Definition Vision of Everything in Sight
Photochromic TechnologySerengeti's Photochromic lenses adapt to any light condition by reacting to UV radiation. They transition gradually from light to dark based on UV exposure, optimizing for the environment to provide the exact amount of light needed, reducing eyestrain, and enhancing vision in all settings.
Spectral Control TechnologySerengeti's Spectral Control™ technology filters up to 95% of blue light, enhancing colors and contrasts for high-definition vision. By reducing blue light transmission, this technology protects eyes from aging and damage, improves depth perception, and provides vivid, crisp visuals in all light conditions.
Polarization TechnologySerengeti's Polarization technology eliminates 99.9% of glare from distracting, discomforting, disabling, and blinding sources, providing absolute clarity and reducing eye fatigue. This ensures no more reflections from vehicle headlights, intense lights, or shiny surfaces, allowing for ultimate glare protection and uncompromised vision in all environments.
