Trust Kensington, the choice of IT professionals, to help protect the sensitive information on your laptop and reduce the chances of wandering eyes viewing confidential data on your screen. FP Series Laptop Privacy Screens limit the field of vision to +\/- 30 degrees so a person off to the side only sees a dark screen. They are easy to install, either with included frameless tab holders or double-sided tape. The reversible privacy screens also use an anti-reflective coating to reduce glare, and they filter out harmful blue light by up to 30 percent.
