To use the Cora Sunglasses, simply open the frames and place them on your face. Make sure the temples rest comfortably on your ears. When you're not wearing them, avoid leaving them in direct sunlight or in a hot car as this could damage the frames or lenses. To clean the sunglasses, use a soft, lint - free cloth. Gently wipe the lenses and frames to remove dirt and fingerprints. Store them in a protective case when not in use to prevent scratches.
