Privacy Screens

If you work in certain professional fields in a job that requires you to carry a laptop and do your work in places like planes and trains and coffee shops, then there’s a tool that you really need to have: a privacy screen. It’s a screen you put over your laptop’s screen so that it can be seen [almost] normally when looking straight at it, but when you look at the screen at an angle you can’t see anything. More precisely, you can see your screen but someone sitting beside you can’t see it.
