Go to the fabric section of your local wal-mart, and you will see two kinds of clear plastic sheets. one is plain clear, the other has a dark tint. get the dark tint, cut out two copys of your visor, and attach them both.....that should work pretty well. if you want to you can even triple layer it. you'll be able to see through it, and other people won't be able to see in, and it will be somewhat shiny, so it will look like its real. Does that help?
