Shield your MacBook Pro from wandering eyes with the Rocstor PrivacyView Magnetic Privacy Filter for 16" MacBook Pro. This filter limits the viewing angle of your laptop screen to ± 30 degrees while reducing 37% of blue light and glare to help with eye strain. An anti-glare coating further improves the visibility of what is on screen for the user. With the built-in magnetic strip, installation is as easy as setting it against the MacBook screen, and you're good to go.
