Looking for a pair of sunglasses that can handle any adventure? Look no further than the Oakley BiSphaera. The BiSphaera features a similar brow line and stem design to its shield counterpart, the Sphaera. But as its name suggests, the BiSphaera features two lenses instead of one, and is available in prescription. Taking notes from the fan-favorite Flak 2.0 XL, this sunglass has all the performance features you demand, with a modern, cutting-edge style. The sleek design paired with eye-catching and contrast-enhancing PRIZM™ lenses gives you a confident and competitive edge. With its durable O Matter™ frame construction, this pair of sunglasses is built to last. Unobtanium™ anti-slip grip on the nose pads and temples keeps the BiSphaera where it belongs during your most rigorous workouts. This medium-to-large size sunglass has an 8-base wrap and a slightly wider Rx range than the Flak 2.0 XL. Its thin, flexible temples make it easily hat and helmet compatible. Perfect for golf, mountain biking, hiking, and more, these glasses help you achieve it all. Oakley BiSphaera performance sunglasses are the perfect pair of shades for anyone who demands the best in performance and functionality, no matter their sport.

SportRx Frame Width™ 
134mm
134mmSportRx 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.

DETERMINING 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.
