Setup, Compatibility & Care
To ensure your Costa Fly Line sunglasses maintain their performance, follow these maintenance guidelines: Keep your frames stored in a protective hard case when not in use to prevent lens scratches. When cleaning, rinse lenses with fresh water to remove salt or dust before wiping them down with the included microfiber cloth. Avoid using paper towels or abrasive fabrics, as these can damage the lens coatings. While the frame is designed for durability, avoid exposing the glasses to extreme heat, such as leaving them on a car dashboard, which can compromise the structural integrity of the injected material.
