Using these sunglasses is a breeze. Just put them on like you would with any regular pair of sunglasses and enjoy your time outdoors, during travels, or at parties. When not in use, keep them in the provided case to prevent scratches. Clean them with a soft, lint - free cloth. Avoid exposing them to extreme temperatures or chemicals as this may damage the lenses or the frame. Also, be careful when folding and unfolding the frames to avoid breakage.
