Using these sunglasses is simple. Just put them on your face and adjust the temples for a comfortable fit. When not in use, keep them in the provided case to prevent scratches. To clean the lenses, use a soft, microfiber cloth. Avoid using abrasive materials or harsh chemicals as they can damage the lenses and the frame. Don't bend the temples too forcefully as it may cause them to break. Store the sunglasses in a cool, dry place to maintain their quality.
