Using these sunglasses is super easy. Just put them on your face, and they'll sit comfortably on your nose and ears. When you're out in the sun, they'll protect your eyes from harmful UV rays and reduce glare with their mirror - coated lenses. As for care, clean them regularly with a soft, dry cloth to keep the lenses clear. Avoid using harsh chemicals or abrasive materials as they can scratch the lenses. When not in use, store them in a protective case to prevent damage.
