These measurements include the width of the lens, the width of the bridge, the height of the lens and the length of the arms measured in millimeters.
For example, a 56-17-45-144 frame:
1) Lens Width - 56mm
2) Bridge Width - 17mm
3) Lens Height - 45mm
4) Arm Length - 144mm
O Matter Frame Material - This lightweight synthetic is engineered for all-day comfort, shock absorption and durability against the punishment of environmental extremes.
Three-Point Fit - Oakley’s unique Three-Point Fit holds the lenses in precise optical alignment. Their frame materials balance durability and comfort with impact absorption for athletic competition, and these frame geometries maximize your peripheral vision.
Plutonite 100% UV Protection - Lightweight Plutonite® lens material offers superior comfort, clarity and protection against impact and ultraviolet radiation. Maintaining the proven safety characteristics of Oakley eye-wear, the impact-resistant material blocks 100% of all UVA, UVB, UVC and harmful blue light.
XYZ Optics - If you want to conquer the world, you have to be able to see it. XYZ Optics® maintains clarity all the way to the lens periphery where conventional lenses normally distort vision.
HD Polarized - Oakley HD Polarized sunglasses block 100% of all ultraviolet light. Because building an optical force-field means protecting you from everything but the safest, clearest, most glare–free light. Ultimate clarity and protection, made to meet the demands of the world's greatest athletes.
Polaric Ellipsoid Geometry - Minimizes optical distortion in single-lens eyewear. This patented geometry minimizes optical distortion and achieves precise orientation between the human eye and each point along the curvature of the lens.
This allows single-lens sports shields that maximize peripheral clarity while providing protection against sun, wind and side impact.
Iridium - Oakley Iridium® lens coatings allow the wearer to tune transmission for any light condition. Superheated metallic oxides are fused to the lens at the molecular level, permanently bonding to create a uniform filtering layer that optimizes contrast and minimizes glare.
Tuned to transmit from 9 to 92 percent of available light, the coatings are specifically formulated for optimal balance between reflection, transmission and absorption, depending on the targeted environment for usage.
Meets ANSI Z87.1 Impact Standards - Impact protection based upon ANSI Z87.1 test methods for high mass and high velocity impact resistance.
