Setup, Compatibility & Care
To ensure your Persol 3304S sunglasses last, keep them stored in a protective case whenever they are not being worn to prevent accidental impacts or lens scratching. For cleaning, use only a microfiber cloth and, if necessary, a gentle, non-abrasive lens cleaner. Avoid using harsh chemicals or paper products that can strip protective coatings. When putting them on or taking them off, use both hands to avoid putting unnecessary stress on the hinges and frame alignment. For those requiring a specific fit adjustment, it is recommended to visit a professional optician to avoid damaging the frame material.
