*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.
Oakley Hydra sunglasses are every longtime Oakley fan’s favorite new shades. The Razor Blades-inspired frame features a semi-rimless cylindrical lens, and trigger stem temples that showcase Oakley pride with the B1B logo. The frame taps into surfing heritage with Oakley’s eco-friendly BiO-Matter, a new plant-based resin that helps reduce your carbon footprint. As a plus, no need to worry about the fit of the Hydra’s nosepad. It comes with two interchangeable nosepad pieces, complete with Unobtainium grip to hold your sunglasses in place. To top it all off, Oakley’s PRIZM Lens Technology enhances the colors and contrast of world around you. Don’t miss out on this nostalgic frame and get your Oakley Hydra online at SportRx today!
