Setup, Compatibility & Care
To ensure your BC4020S sunglasses remain in peak condition, store them in the provided protective case when not in use. Avoid leaving the frames in extreme temperatures, such as a hot dashboard, which can warp the frame material or damage the lenses. Clean the lenses only with a microfiber cloth and a mild lens cleaning solution; avoid paper towels or clothing, which may scratch the delicate lens surface. If the hinges feel loose over time, take the pair to a professional optician for a precise adjustment rather than attempting to tighten screws yourself.
