Using these glasses is a breeze. Just put them on your face and adjust the arms to fit comfortably. They're great for daily use, like when you're out in public or doing tasks where your eyes need protection. When it comes to maintenance, you can simply clean the clear visor with a soft, damp cloth. Avoid using harsh chemicals as they might damage the plastic. Keep them in a safe place when not in use to prevent scratches. And remember, if the arms get loose over time, you can easily readjust them to keep the glasses fitting well.
