Using these sunglasses is simple. Just put them on your face like you would with any regular pair of glasses. When you're wearing them, they'll block harmful UV rays and give you a cool look. As for precautions, don't scratch the lenses with sharp objects. Avoid leaving them in extremely hot places, like inside a parked car on a sunny day. For maintenance, clean the lenses with a soft, lint - free cloth. You can also use a mild lens cleaner. If the frame gets dirty, you can gently wipe it with a damp cloth and then dry it thoroughly. This will keep your sunglasses in good condition for a long time.
