[Michlib-l] privacy screens

Good afternoon, We are having an issue with patrons monitoring what other patrons are doing on our public computers. I purchased some privacy screens for the computers, but was disappointed to discover that they actually only block the view if you are sitting beside the computer. If you walk by, even 12 feet away, you can still see the screen as clearly as if there was no filter. Can anyone recommend a better privacy screen? Or, failing that, another solution? Turning the computers is not an option. We don't have room. Thanks, Marian -- Marian Veld Currently reading: Quicksand by Junichiro Tanizaki
