This Privacy Screen for 12.3-inch Surface Pro 4, 5, 6, 7, and 7+ models smoothly transitions from a clear view to an obscured screen beyond the intended viewing angle, significantly enhancing visual privacy in office or public environments. The anti-glare matte finish helps to reduce reflections in glare-prone environments and provides additional screen protection with a scratch and fingerprint-resistant coating. 4-Way Privacy and Touch Support The security filter ensures optimal privacy in portrait or landscape orientations when viewed beyond 30° from the center, covering a total visible area of 60°. It supports touchscreen input and gestures, preserving the interactive experience of a Surface Pro while maintaining the confidentiality of on-screen content. Installation The screen protector is compatible with the 12.3" Surface Pro 4, 5, 6, 7, and 7+ models and features a precise fit that does not interfere with the display, camera, or speakers. The included installation kit and step-by-step instructions allow for a one-time application to the computer screen. Blue Light Reduction This Blue Light Reduction Privacy Shield reduces eye strain and improves visual comfort by blocking 40% - 51% of the blue light emitted from the display (in the 380nm - 480nm wavelength range). Symptoms of digital eye strain, such as headaches, dry eyes, and blurred vision, can be alleviated by using blue-light filtering privacy screens.
