Setup, Compatibility & Care
Because these are premium fashion sunglasses, maintenance is key to their longevity. Always store the glasses in the provided protective case when not in use to prevent scratches. When cleaning, use a microfiber lens cloth and a mild soap-and-water solution if necessary; avoid using paper products or harsh chemicals that could damage the lens coating or the opaline frame finish. The 4480U is designed as a standalone accessory and does not require complex adjustments, though minor fitting can be performed by an optical professional if the temple arms require tightening.
