Orange Sunglasses versus Haze

Look at a hazy sky through orange or red glasses or goggles and clouds and distant objects on the horizon will pop into view. Why does this happen?

Remember why the sky is blue? Air molecules scatter blue light more efficiently than other colors. Orange or red glasses block most blue light, making the sky appear dark on a clear day. The glasses seem to penetrate haze because they block most light scattered by air molecules and some light from haze, thus allowing you to see distant objects that would otherwise be hidden in haze.
