Setup, Compatibility & Care
To ensure your sunglasses remain in top condition, handle them by the temples rather than the lens surface to minimize oil transfer. When not in use, always store the PH4204U in a protective hard-shell case to prevent scratching the lenses. To clean, rinse under lukewarm water with a mild, non-abrasive soap, then dry with a clean microfiber cloth. Avoid using paper towels or tissues, as these can contain wood fibers that cause microscopic scratches on the lenses over time. If the temples feel too loose or tight, consult a professional optician for a frame adjustment to ensure optimal comfort.
