The world's best athletes are constantly looking for an edge. That's what helped inspire the creation of Oakley's Sphaera sunglasses. Using the lessons learned from Oakley's team athletes as a foundation, designers combined functional needs with elements of heritage to create a frame that offers a unique solution for athletes seeking maximum performance. The combination of the lens shape, made possible by PhysioMorphic Geometry, with a cut inspired by one of the legacy models, Razor Blades, offers coverage and style. At the same time, the sunglasses' vented design allows for optimal airflow. The frame is made of O Matter for strength, comfort, and durability. The Sphaera sunglasses are designed for multisport use, providing optimized coverage, a wider field of vision, frame retention, and impact protection. The lens design has been transformed to offer a more wrap-around shape and stiffness in key areas, mimicking the structural properties of a frame. The Sphaera sunglasses are available in a unisex design, suitable for both men and women.
