My experience with privacy screens is limited but they are amazing! My desk is in a high-traffic area and my co-workers are constantly commenting on what's on my screen. I work in an academic office, so students would regularly lean over my desk to check their calendars. These screens produce a dimming effect at an angle of about 30 degrees, but they don't disturb my vision as a user at all. I had to increase the brightness/contrast of the screen but I'm very happy with it. Some even commented that they thought my monitors were off! Hooray privacy!
