Rusty, to your first question, yes. To your second, some time ago I noticed the same thing. I have used what I consider to be good quality polarized lenses and they always became opaque when they were offset 90 degrees, regardless of whether they were A, B, or C but I have discovered that some of the cheap ones don’t (I don’t know the manufacture of the lenses and the company I reference uses them because they are very cheap) and I have wondered too, how this could be. I have until now just written it off as a poor quality polarized lens because it is not consistent from manufacture to manufacture. I have to defer to Allen on this one though he understands the process of manufacturing and may have some insight for us.
