Setup, Compatibility & Care
Because the Coach CW428 uses a fixed injected frame, there is no setup required; simply remove them from the protective case and adjust the temples naturally as you put them on. For long-term maintenance, keep the sunglasses in their provided hard case whenever they are not in use to prevent surface scratches. To clean the lenses, use only a soft microfiber cloth and a mild lens cleaner specifically designed for optical eyewear. Avoid using paper towels or abrasive fabrics, as these can permanently damage the lens coating. If the frame feels slightly loose or tight, avoid heating the injected plastic yourself, as this can weaken the material; visit a professional optician for expert adjustments.
