Setup, Compatibility & Care
To ensure the longevity of your Ray-Ban Kai sunglasses, always store them in a protective hard case when not in use. To clean, use a microfiber cloth and a mild soap-and-water solution; avoid using household cleaners or abrasive paper towels that can scratch the lens coating. If the frame feels loose or sits unevenly, visit an authorized Ray-Ban retailer for a professional adjustment rather than bending the metal temples yourself to prevent damaging the finish.
