To use these sunglasses, simply put them on like you would any other pair. Make sure the temples rest comfortably over your ears. When you're not wearing them, store them in a protective case to prevent scratches. To clean the lenses, use a soft, lint - free cloth. Avoid using harsh chemicals as they can damage the plastic lenses or acetate frame. If you need to adjust the fit, gently bend the temples. Always handle your sunglasses with care to keep them in top condition.
