How to use: Simply put on the safety glasses like you would with regular glasses. They're designed to fit comfortably on your face for long periods. Note: Don't scratch the anti - fog coating. Avoid exposing them to extreme heat or cold. Maintenance: Clean the glasses with a soft, dry cloth. If they get dirty, you can use a mild glass cleaner and then dry them thoroughly. This will keep them in good condition and ensure they continue to protect your eyes effectively.
