How to use: Just put on these sunglasses like you would with any other pair. They are great for outdoor activities such as going to the beach, having a picnic, or taking a walk. Note: Avoid scratching the lenses. When not in use, store them in a protective case. Maintenance: Clean the lenses with a soft, lint - free cloth. You can use a mild lens cleaner if needed, but make sure to dry them thoroughly after cleaning.
