Specifications Summary: Screensize: 15.6 in, This laptop privacy screen features a universal design, compatible with 15.6-inch laptops with a 16:9 aspect ratio. The gold finish enables a faster transition to a mirrored finish to block the contents on the display. The privacy filter prevents visual eavesdropping by blocking the screen from the side while maintaining a clear viewing angle of 60 degrees (+/- 30 degrees from the center) for the user. The privacy screen protector is reversible, with a glossy gold side for maximum privacy and an anti-glare matte side for environments prone to glare. The matte side provides additional screen protection with a scratch and fingerprint-resistant coating. The universal design won't interfere with top-mounted webcams, sensors, or when closing the lid. The filter blocks 40% - 51% of the blue light emitted from the display in the 380nm - 480nm wavelength range. Digital eye strain can lead to symptoms like headaches, dry eyes, and blurred vision. This laptop privacy filter is backed for two years, including free lifetime 24/5 multi-lingual technical assistance.
