During activities where you keep your head tucked low, like cycling, the upper frames of most sport sunglasses will get in the way of your vision. Oakley addressed this problem with the Radarlock XL Sunglasses, which feature a 19mm nosebridge height that provides a larger field of view so you don't have to keep lifting your head to see under the frame.
