How to use: Simply put on the sunglasses like you would with any other pair. They're great for sunny days, whether you're driving, walking, or at the beach. Note: Don't leave them in a hot car as extreme heat might damage the frame or lenses. Also, avoid scratching the lenses with sharp objects. Maintenance: Use a soft, clean cloth to wipe the lenses and frame regularly. When not in use, store them in the provided case to prevent scratches and damage.
