Protect sensitive data from prying eyes with Kensington's Privacy Screen for 12.5" Laptop. This 16:9 privacy screen protector mounts to a laptop's 12.5" screen using the included double-sided tape or frameless tab holders, which allow you to flip the protector to provide a glossy or matte finish. Once installed, it limits the viewing angles by ±30°, so only you can see what's on the laptop's display. Aside from limiting viewing angles, the screen protector filters out blue light by up to 30% and reduces glare from light sources when utilizing the matte side. Furthermore, the glossy side of the screen protector provides a clearer view than the matte finish.
