Setup, Compatibility & Care
To ensure your COACH HC8409U sunglasses stay in top condition, avoid placing them face down on hard surfaces to prevent lens scratches. When not in use, always store them in a protective hard-shell case. For cleaning, use a microfiber cloth and a gentle lens cleaning solution; avoid using household paper towels or napkins as they can contain wood fibers that may cause micro-abrasions. If the arms feel loose over time, take them to a professional optician for a minor screw adjustment rather than attempting to force a fix yourself.
