The RB4391D is a ready-to-wear accessory that requires no assembly. To ensure longevity, always use the provided microfiber cloth to clean the lenses, as this prevents scratching from dust particles. When not in use, keep the sunglasses in a protective case to prevent bending or impact damage to the frame. Avoid placing the glasses face-down on hard surfaces to protect the integrity of the lens coating. If the hinges feel loose over time, seek assistance from an authorized optical professional for minor adjustments to the screw tension.
