Not fully matched in light rejection but good enough for photographers and others it seems.
Not full polarization, but still usable for my purposes. I don't think these are made accurate enough to work on a screen. They also let about 10% of the light through when they are upright. That means they don't work for the classic blackout experiment. They would probably still be useful for photography and lighting. You might want to look for something more expensive if you want impressive performance.
