Even the world's best athletes start out small, so we engineered a youth frame that's big on protection. The look is pure Oakley and the science is High Definition Optics® (HDO®), a collection of technologies that maximize clarity. Pure Plutonite® lenses filter out 100% of all UVA, UVB and UVC, and combined with this durable O Matter® frame, they meet ANSI standards for impact resistance. The "XS" stands for "extra small," so these sunglasses are for the young and reckless.
High Definition Optics® (HDO®) is a collection of patented technologies that allow Oakley eyewear to meet or exceed the testing standards of the American National Standards Institute for optical clarity, visual fidelity, and impact resistance.
