Regularly clean the lenses and frame using a soft, lint-free cloth to remove dust, dirt, and smudges, avoiding abrasive materials that may scratch them. Refrain from using harsh chemicals, alcohol-based cleaners, or ammonia-based products to prevent damage to the polycarbonate material and maintain its clarity. When not in use, store the sunglasses in a protective case to shield them from potential scratches and accidental damage, avoiding pockets or bags without protection.
