Setup, Compatibility & Care
To ensure the longevity of your Persol 3367S sunglasses, start by having them adjusted at an authorized optical retailer to match the contours of your face perfectly. When not in use, always store the glasses in the provided protective hard case to prevent lens scratches and frame pressure. Clean the lenses exclusively with a microfiber cloth and a mild optical cleaning solution; avoid using paper towels or abrasive household cleaners, which can damage lens coatings. If the hinges feel loose after extended use, visit an optician to have the screws tightened rather than attempting a DIY fix.
