Setup, Compatibility & Care
Upon receiving your Coach Ch569 sunglasses, perform a quick inspection to ensure the frame sits evenly on a flat surface. To maintain the longevity of your sunglasses, always store them in a protective hard case when not in use. Clean the lenses using a microfiber cloth and a mild lens cleaning solution; avoid using abrasive fabrics like paper towels or tissues, which can cause micro-scratches on the gradient coating. For long-term maintenance, have the hinge tension adjusted by a professional optical specialist if the arms begin to feel loose.
