pOur Three-Point Fit maximizes comfort while holding the lenses in precise optical alignment, letting the innovations of High Definition Optics (HDO) do their work. Optical performance and impact protection meet ANSI Z87.1 standards, and with 8.75 base lens curvature, you’ll have extended peripheral vision and improved side protection against sun, wind and impact. Patented XYZ Optics helps keep vision sharp at every angle of view. We engineered this sunglass with durable yet lightweight O Matter and matched it with pure Plutonite lenses that filter out all UV./ppFives Squared can be fitted with Oakley Authentic Prescription Lenses. Plenty of colors are available for our premium corrective lenses, and if you choose the non-prescription version, you can pick from a range of popular hues. Options include Iridium coated lenses that precisely balance light transmission and reduce glare, as well as Oakley polarized lenses that kill 99% of glare without muddying your vision with the haze and distortion found with ordinary polarized lenses./ppSometimes truer color recognition is essential, like when you’re biking down a mountain and you need to see where the brown of the trail meets the green of the shrubs. Available lenses that help maintain color recognition include Warm Grey, Black Iridium and Black Iridium Polarized for bright sun, or Grey for medium bright light. When you need visual contrast and enhanced depth perception, your best choice is Dark Bronze or Bronze Polarized, both of which work well in bright sunlight./pul class="default_listitem"li Durability and all-day comfort of lightweight, stress-resistant O Matter frame material/lili Comfortable fit on small to medium faces via condensed cranial geometry/lili Patented hydrophilic Unobtainium nosepads ensure a snug, secure fit, and increase grip with perspiration/lili Precision and durability of sculpturally integrated hinge mechanisms with dual action CAM/lili Optimized peripheral vision and side protection of 8.75 base lens curvature/lili Comfort and Performance of Three-Point Fit that holds lenses in precise optical alignment/lili Metal Square O Icon design/lili Optical precision and performance that meets ANSI Z87.1 standards/lili Impact resistance that meets ANSI Z87.1 basic impact standards/lili Maximum clarity at all angles of vision with patented XYZ Optics/lili UV protection of Plutonite lens material that filters out 100% of UVA / UVB / UVC & harmful blue light up to 400 nm/lili Glare reduction and tuned light transmission of Iridium lens coating (optional)/lili Minimized glare via technology that produces the best polarized lenses on the planet with greater than 99% polarization efficiency/li/ul
