Your digital camera does not have that issue, so you might find what you see and what you capture look differently anyway. A CPL will adjust contrast but its primary purpose is to affect the way polarised light is dealt with. It can be very useful. But if the haze is pollution, dust, smog, smoke etc in the atmosphere, there is really no way to see through it, either with your eyes, or with your camera.
