PORT Professional Privacy filters are designed to preserve the confidentiality of the information displayed on a computer screen. Once positioned, only the user located in front of the screen is able to view the information and anyone located laterally at more than a 30 ° angle from the screen will see anything other than the black opaque filter. Perfectly adapted to mobility, it ensures the confidentiality of computer screens especially at work and during travel: ideal for offices, open spaces, airports, airplanes, trains, cafes and other public places. Work productively anywhere without worrying about prying eyes.
