Setup, Compatibility & Care
To ensure the longevity of your PH4251U sunglasses, keep them in a protective hard case whenever they are not in use to prevent the transparent frame from scratching. When cleaning, use only a microfiber cloth and a mild lens cleaning solution; avoid paper towels or tissues, which can leave microscopic scratches on the lenses and frame. For adjustments, take the frames to a professional optician to avoid bending the temple arms or bridge, which could lead to material fatigue. Regularly check the hinge screws to ensure they remain snug for a consistent fit.
