Setup, Compatibility & Care
To ensure the longevity of your Costa Finlet sunglasses, store them in a protective hard case when not in use. Use a microfiber cloth for cleaning to prevent micro-scratches on the lens surface; avoid using household paper towels or napkins which can contain wood fibers that damage coatings. If the frames become soiled with salt spray or sweat, rinse them gently with fresh water and a mild, pH-neutral soap before drying. Avoid leaving the glasses in extreme heat, such as inside a vehicle dashboard, as this can compromise the integrity of the frame materials and lens coatings.
