Correct, i forgot to mention, Polycarbonate RX lenses fog, protective ones doesn't fog as much as they do, I think it's about the amount of heat they can take away from the air, and this depends on the surface, material, the amount of energy it can store, etc.
Polycarbonate RX lenses (especially thinned ones, lenses need to be dense to do their jobs, if you use denser lens, you can leave it thinner while trying to reflect the same amount of light) are really dense and solid, but protective ones are less dense.
So if you want the polycarbonate to have lens, reflective features, it has to be dense. But if you are not using it as a lens, just a glass, it can be less dense.
These are just my theories, correct me if i'm wrong.
