How to use: Simply put on the sunglasses and adjust them to fit your face comfortably. They're great for wearing outdoors, whether you're driving, going to the beach, or just taking a walk. Note: Avoid scratching the lenses. Don't leave them in direct sunlight for a long time as it may damage the frame. Maintenance: Clean the lenses with a soft, clean cloth. You can use a mild lens cleaner if needed. Store them in a protective case when not in use to prevent them from getting bent or scratched.
