Setup, Compatibility & Care
To ensure your Costa Ulu sunglasses remain in peak condition, always store them in a protective microfiber or hard-shell case when not in use. Avoid leaving them on your car dashboard, as extreme heat can warp the frame or damage lens coatings. To clean the lenses, rinse them with fresh water to remove any grit or dust particles, then gently dry them using a clean, lint-free microfiber cloth. Never use paper towels, tissues, or abrasive fabrics to clean the lenses, as these can leave permanent scratches on the optical surface.
