Store your sunglasses in a hard-shell case when not in use.
Clean lenses with a microfiber cloth only — avoid paper towels or clothing, which can cause micro-scratches.
Never leave them in a hot car or in direct sunlight for extended periods, as heat can warp frames and damage lens coatings.
Keep them away from harsh chemicals like sunscreen or perfume, and always handle with both hands to maintain frame alignment.
