Using these anti - blue light computer glasses is easy. Just put them on like you would with regular glasses when you're using your computer. Make sure the frame sits comfortably on your nose and ears. When it comes to maintenance, use a soft, clean cloth to gently wipe the lenses to avoid scratches. You can also use a mild lens cleaner if needed. As for storage, keep them in a protective case when not in use to prevent damage. Be careful not to bend the frame too much, as it might affect the fit and durability.
