Setup, Compatibility & Care
Because the HC8328U is a fixed-frame design, no assembly is required. To maintain the longevity of your sunglasses, store them in a protective hard-shell case when not in use to avoid scratches on the lenses or bending of the frame arms. Clean the lenses using a microfiber cloth and a dedicated lens cleaning solution; avoid using abrasive paper products or household chemicals, which can strip the lens coating. If the frames feel loose after prolonged use, consult an optical professional for minor tension adjustments to the temple hinges.
