Description: Privacy filter goes black for anyone viewing the screen from the side, yet no blurring or distortion for the person directly in front of the screen. Reversible - Matte finish to help reduce glare, or glossy for enhanced contrast. Acts as a protective film against fingerprints, dust and scratches. Filter stays in place even if used on a notebook (mounting tabs included). Approximately 65% of light will pass through this filter, 35% will be blocked.
