Setup, Compatibility & Care
To ensure your Coach HC7128 sunglasses maintain their appearance and functionality, always store them in a protective hard-shell case when not in use to avoid accidental crushing or scratching. Clean the lenses exclusively with a microfiber cloth and a mild lens cleaning solution; avoid using abrasive fabrics like paper towels or clothing, which can create micro-scratches on the lens surface. If the hinges feel loose over time, take them to a professional optician for a quick adjustment rather than attempting to tighten them yourself with standard household tools.
