Setup, Compatibility & Care
To maintain the appearance and functionality of your Coach Cr615 8404U sunglasses, store them in a protective hard case when not in use to prevent scratching the gradient lenses. To clean the frames and lenses, use only a microfiber cloth and a mild lens cleaning solution; avoid using paper towels or abrasive fabrics that could cause micro-scratches. If the fit becomes loose over time, take them to a professional optician for a frame adjustment to ensure the stems sit correctly behind your ears. Avoid leaving the glasses on your car dashboard, as extreme heat can compromise the integrity of the frame materials and lens coatings over time.
