Setup, Compatibility & Care
To ensure your Persol PO1009S sunglasses provide long-lasting service, store them in a protective hard-shell case when not in use. Clean the lenses and metal frame exclusively with a microfiber cloth and, if necessary, a dedicated lens cleaning solution; avoid using abrasive paper towels or household glass cleaners, which can strip protective coatings. If the fit feels loose, take them to a professional optician to have the hinges or temple tips adjusted to your face shape, as attempting to force a fit change manually can cause the metal frame to fatigue or break.
