How do you recognize and see the difference between a Cloudy/Muddy/Foggy finder and a "clean" one? How does it hurt the image taking process?

Thanks in advance for your input!
Because when you look through it, it looks Cloudy/Muddy/Foggy. It is not the taking lens which maybe ok, but hinders clarity of vision and your decision as to if/when you press the shutter.
