The Three-Point Fit optimizes comfort while keeping the lenses in precise optical alignment. Take a close look at how the lenses contour at the sides, maximizing protection against sun, wind and side impact. It’s a full 8.75 base lens curvature that utilizes patented XYZ Optics to offer razor sharp clarity at every angle of view. You’ll have extended peripheral vision and performance that meets ANSI Z87.1 standards, thanks to High Definition Optics (HDO). Oakley HDO also means protection, so Split Jacket meets ANSI Z87.1 standards for high velocity and high mass impact resistance. Our Plutonite lens material filters out every eye-baking ray of UV, not just UVA and UVB, and you’ll have a wide array of lens options to adapt to any environment. When reflected glare threatens your vision, install optional Oakley HDPolarized lenses.
