Oakley Flak Jacket Sunglasses Replacement Lenses - Black Iridium Polarized (13-651)

If you always train and compete in the same place, at the same time of day and in the same weather, one pair of lenses is enough. The real world demands more flexibility, so when Oakley invented Flak Jacket, they created an interchangeable lens design that lets you adapt for the best performance possible – right here, right now.

Multiple options are available including Iridium lens coatings that reduce glare and balance light for whatever the sun dishes out. You can also get the best polarized lenses on the planet. Oakley polarization technology uses a liquid infusion process to bond the polarizing filter at the molecular level. That’s how Oakley eliminates the haze and distortion found with conventional technologies and achieve unbeatable glare-cutting performance.

High Definition Optics (HDO) maximizes clarity with patented innovations like XYZ Optics, a geometry that maintains razor-sharp vision at every angle of view. Oakley's durable Plutonite lens material offers superior impact protection and filters out 100% of all UV rays, not just UVA and UVB. Fits standard and Asian fit Flak Jacket frames.
