Loaded with new tech features, these Oakley Top Knot eyeglasses combine fun and function in a pair of stylish frames. The large, round frames are a fresh take on the traditional cat eye style, providing definition for oval, rectangular, square, and heart-shaped faces. Constructed from O Matter and boasting C5 alloy temples, these lightweight, durable frames handle impact from an active lifestyle. Spring hinges allow the temples to open past the typical 90-degree angle for additional flexibility and resilience. Designed specifically for women, these O Matter-frame Oakley eyeglasses feature no-snag nose pads that prevent hair from getting tangled in them.
