*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.
The Oakley Flak 2.0 XL has been an Oakley staple for years now. Its predecessor, the Flak Jacket XLJ, was already a great frame and Oakley fine-tuned it to make it even better! The 'XL' refers to the taller lenses which provide more coverage, but there is also a Flak 2.0 (non-XL) with the exact same frame chassis and slightly shorter lenses. Oakley Flak 2.0 XL sunglasses are constructed with Oakley’s proprietary O Matter™ for amazing durability and ultra-lightweight comfort. Unobtainium® earsocks and nosepads and Oakley’s Three-Point-Fit system help keep your glasses securely in place even if you break a sweat. If you are interested in using these for a particular sport, you should really check out PRIZM™ lenses. These are sport-specific lenses that boost contrast and allow you to perform at your best! Need prescription Oakley Flak 2.0 XL sunglasses? Done. Call or chat with our friendly Sports Opticians if you have any questions about ordering Oakley Flak 2.0 XL prescription sunglasses. And as always, we offer free shipping & returns!
