These fashionable men's sunglasses are super easy to use. Just put them on your face like you would with any regular pair of glasses. When you're out in the sun, they'll protect your eyes from harmful UV rays and give you a trendy look. Remember to handle them gently. Don't bend the frames too much or drop them on hard surfaces. To keep them clean, use a soft, clean cloth to wipe the lenses. You can also wash the frames with mild soap and water, but make sure to dry them thoroughly. Store them in a protective case when you're not wearing them to prevent scratches.
