The Oakley Bisphaera 9400 sunglasses deliver performance-driven versatility for athletes who refuse to choose between sport and style. Built around a modern dual-lens rectangular design, the Bisphaera bridges the gap between dedicated sport frames and everyday wear—making it the go-to choice for runners, cyclists, and active lifestyles that demand both function and a clean aesthetic.
Prizm Lens Technology: See More Detail
Available with Oakley's Prizm lens technology, the Bisphaera 9400 doesn't just darken your view—it fine-tunes it. Prizm lenses work by selectively filtering specific wavelengths of light to boost contrast and enhance color in your environment. The result is sharper vision, better depth perception, and reduced eye fatigue across a range of conditions. From Prizm Road for cycling to Prizm Deep Water Polarized for fishing, each lens variant is engineered for a specific activity. All lenses block 100% of UVA, UVB, and UVC rays up to 400nm, protecting your eyes without compromise.
Built for Comfort and Retention
The lightweight O Matter frame keeps the Bisphaera comfortable through long days and hard efforts. Unobtainium nosepads and earsocks increase grip as you sweat, so the frame stays put during interval sprints or rough trail descents. The half-rim design with a single bridge offers a secure fit without the bulk of full-shield frames. The Bisphaera is also prescription-ready, with Oakley Authentic Prescription lenses available and laser-etched with the ellipse logo for authenticity. The 68mm lens width and rectangular shape suit medium to large faces, and the 8-base wrap provides solid coverage without feeling aggressive.
Designed to move from the starting line to the coffee shop without missing a beat, the Oakley Bisphaera 9400 is the frame for athletes who live in motion.

Frequently Asked Questions
Are the Oakley Bisphaera 9400 sunglasses available with prescription lenses?
Yes, the Oakley Bisphaera 9400 is prescription-ready. You can order Oakley Authentic Prescription lenses that are laser-etched with the ellipse logo for proof of authenticity. The frame accommodates a wider prescription range than some other Oakley sport models, making it a versatile option for athletes who need vision correction.
What is Oakley Prizm lens technology and how does it work?
Prizm is Oakley's spectral tuning technology that enhances contrast and color by selectively filtering specific wavelengths of light. Unlike standard tints that simply darken your view, Prizm lenses are engineered for specific environments—boosting the colors and details that matter most for your activity while blocking wavelengths that cause visual noise. All Prizm lenses provide 100% UV protection up to 400nm.
Do the Oakley Bisphaera 9400 sunglasses provide UV protection?
Yes, all Oakley Bisphaera 9400 lenses block 100% of UVA, UVB, and UVC rays up to 400nm. Oakley lenses are made from Plutonite, a high-purity optical-grade polycarbonate that provides complete UV protection and impact resistance, ensuring your eyes are protected in demanding conditions.
How does the Oakley Bisphaera compare to the Flak 2.0 XL?
The Bisphaera takes design cues from the fan-favorite Flak 2.0 XL but features a more modern brow line and stem design. Both share similar performance features like O Matter frames and Unobtainium grip, but the Bisphaera offers a slightly wider prescription range and an 8-base wrap. The Bisphaera is designed as a versatile option that transitions more easily from sport to everyday wear.
What size face do the Oakley Bisphaera 9400 sunglasses fit?
The Oakley Bisphaera 9400 is designed for medium to large faces. With a 68mm lens width and an 8-base wrap, it provides solid coverage and retention. The frame features adjustable Unobtainium nosepads for a customized fit, and the 136mm temple length ensures a secure, comfortable fit for extended wear during athletic activities.
Are the Oakley Bisphaera 9400 lenses interchangeable?
Yes, the Oakley Bisphaera 9400 features interchangeable lenses. Oakley offers authentic replacement lenses in multiple Prizm variants including Prizm Road, Prizm Black Polarized, Prizm 24K Polarized, and Prizm Dark Golf, allowing you to swap lenses based on your activity or lighting conditions. Replacement lenses are covered under Oakley's warranty policy.

Oakley Bisphaera 9400 vs. Flak 2.0 XL vs. Radar EV Path
Choosing between the Oakley Bisphaera 9400, Flak 2.0 XL, and Radar EV Path comes down to how you balance sport performance with everyday versatility. All three are dual-lens rectangular frames built for athletes, but each takes a different approach to coverage, fit, and style.
The Bisphaera 9400 is the most versatile of the three. It shares the performance DNA of the Flak 2.0 XL but updates the design with a modern brow line and stem that look just as good off the bike as on it. The Bisphaera also offers a wider prescription range, making it the best choice if you need vision correction. At $193–$278, it sits in the middle of the price range and delivers the best balance between sport function and everyday wearability.
The Flak 2.0 XL ($146.66–$267) is the proven workhorse. It's been refined over years of athlete feedback and remains a favorite for runners and cyclists who want a no-nonsense performance frame. The Flak 2.0 XL is slightly less expensive and has a massive lens replacement ecosystem, but its design skews more sport-specific and less lifestyle-friendly than the Bisphaera.
The Radar EV Path ($147.92–$297) is the dedicated race-day choice. Its extended vertical lens height provides superior upper peripheral coverage, making it ideal for cycling and running where you need to see the road or trail ahead. However, the Radar EV's aggressive sport aesthetic and taller lens make it less versatile for casual wear compared to the Bisphaera.
Our take: If you want one frame that performs on the trail and looks sharp at the coffee shop, the Bisphaera 9400 is your best bet. If you prioritize pure sport performance and maximum coverage, the Radar EV Path delivers. And if you want a proven, budget-friendly option with a massive aftermarket, the Flak 2.0 XL is hard to beat.
