How to use: Simply put on the sunglasses like you would with any regular pair. They're perfect for wearing during outdoor sports such as flying, running, or cycling. When you're done using them, keep them in a safe place. Avoid leaving them in direct sunlight for long periods as this may damage the lenses or frames. Cleaning is easy. Use a soft, clean cloth to wipe the lenses gently. If they're very dirty, you can use a bit of mild soap and water. Just make sure to dry them thoroughly before storing. Also, be careful not to scratch the lenses when handling the sunglasses.
