Oakley CYBR Lightning Low-Light Sunglasses The clean CYBR rimless aesthetic delivers a confident, streamlined look, while the Prizm Low Light lenses are engineered to maximise contrast and improve visibility in darker conditions, making them particularly suited to early-morning starts, overcast days and shaded routes. The vented lens design promotes airflow to help reduce heat and improve comfort during intense efforts, while Oakley lenses are designed and tested under extreme high-mass and high-velocity conditions for dependable protection in demanding environments. For a secure fit, the Unobtainium® nosepads and ear socks increase grip with perspiration, keeping the sunglasses firmly in place as your effort builds. The lightweight O-Matter? frame provides strength and flexibility, with excellent resistance to shifting or deforming over time. Whether you're heading out before sunrise or tackling a run beneath heavy cloud cover, the Oakley CYBR Lightning with Prizm Low Light lenses offers lightweight performance, secure comfort and enhanced visibility when you need it most.
