To use these sunglasses, simply place them on your nose and adjust the arms to fit comfortably on your ears. When you're out in the sun, they'll protect your eyes and make you look stylish. Remember not to bend the frames forcefully as it may damage the structure. For cleaning, use a soft microfiber cloth to gently wipe the lenses. Avoid using harsh chemicals as they can scratch or discolor the lenses. Store them in a hard - case when not in use to prevent scratches and breakage.
