Using these Le Specs Under Wraps sunglasses is easy. Just put them on your face like you would with any other pair of sunglasses. When not in use, keep them in a case to protect them from scratches and damage. Clean the lenses with a soft, microfiber cloth to avoid leaving scratches. Don't expose them to extreme temperatures for a long time as it might affect the frame and lenses. And make sure to store them in a dry place to prevent any moisture damage.
