If sunglasses tend to sit too low on your face or slide down your nose, touch at your temples or cheeks, or feel narrow at the sides of your head, try our Asian Fit. The bridge is narrowed and deepened, and longer pad mounts are used on certain frames to give you more room for adjustment. The Screw-In Pad articulates to conform nose point of contact while the snake pad arm curves to give you more room for adjustment. And the specially sized nose pads help the frame sit higher on the face and stay comfortably in place. LEARN MORE ABOUT OAKLEY ASIAN FIT
