Shaped with the curves of rounded lenses for a classic lifestyle look, these new Oakley sunglasses got their name from the smooth center line that runs down surfboards, and the stems follow that pure approach with clean contours of sculpture. The sunglasses boast: Durability and all-day comfort of lightweight, stress-resistant O Matter™ frame material. Comfort and performance of Three-Point Fit that holds lenses in precise optical alignment. UV protection of Plutonite® lens material that filters out 100% of UVA / UVB / UVC & harmful blue light up to 400nm. Optimal precision and impact resistance that meet or exceed ANSI Z80.3 optical and basic impact standards.
