To use these glasses, simply put them on your face like regular glasses. They're great for casual outings, parties, or just adding a bit of flair to your daily look. When it comes to cleaning, use a soft, dry cloth to gently wipe the lenses and frames. Avoid using harsh chemicals as they may damage the plastic. Store them in a safe place, like a glasses case, when not in use to prevent scratches and keep them in good condition.
