Setup, Compatibility & Care
To ensure your Coach sunglasses maintain their condition, store them in a hard-shell case when not in use, preferably inside a lint-free pouch to avoid micro-scratches. Avoid placing the glasses face-down on hard surfaces to protect the lens coating. When cleaning, use only a microfiber cloth and a mild soap-and-water solution or dedicated lens spray; avoid using paper towels or abrasive fabrics which can damage the lens clarity over time. Ensure the hinges are checked periodically for tension and tighten them with a small precision screwdriver if the arms begin to feel loose.
