Setup, Compatibility & Care
To ensure the longevity of your Costa Broadbill II sunglasses, store them in a protective hard case whenever they are not in use to prevent pressure damage to the lenses. When cleaning, use only a microfiber cloth and lens-safe cleaning solution; avoid using paper towels, tissues, or abrasive fabrics that can permanently scratch the mirror coating. If the sunglasses are exposed to saltwater, rinse them thoroughly with fresh water and dry them with a soft cloth to prevent salt buildup on the frame hinges or lens surface. Proper care prevents corrosion of the metal components and maintains the integrity of the polarized layers.
