These men's sunglasses are easy to use. Just put them on your face like you would with any regular pair of glasses. They're great for outdoor activities as they have UV400 protection and polarization to reduce glare. When not in use, store them in the provided case to prevent scratches. Clean the lenses with a soft, lint - free cloth. Avoid using harsh chemicals or abrasive materials as they can damage the lenses and the frame. Also, don't leave them in direct sunlight for long periods as it might affect the photochromic feature.
