Protect your screen and your own privacy. Protect your company – both on the move and in the office – by keeping login credentials, essential personal and confidential data and information unexposed to unwanted onlookers. With a Gearlab privacy filter, you get crisp and clear image clarity when you are in front of the screen, while people on either side cannot see anything on your display.
As an additional benefit, a privacy filter protects the sensitive screen glass surface from scratches and damage, and like on a touchscreen, your fingers slide and swipe easily across the surface.
