The Oakley Cartwheel is designed to keep up with any girls day. This eyeglass adds more feminine variety to the Youth Oakley Eyeglass Collection. It was specifically designed with the anatomy of a child's face in mind to provide a secure fit. Oakley's proprietary frame material, O Matter, makes these eyeglasses both durable and lightweight. The molded-in nosepads are designed to better fit the underdeveloped nosebridge of the youth wearer. The Cartwheel comes in two sizes and is available with Oakley Authentic lenses.
