Enhanced Privacy Protection: Our computer privacy filter is designed to safeguard your sensitive information from prying eyes. The advanced microlouver technology ensures that only those sitting directly in front of the screen can see the content, effectively blocking visibility from side angles (over 30 degrees). This makes it ideal for use in public places, open offices, or while traveling. Superior Eye Protection: This widescreen monitor screen protector not only protects your privacy but also prioritizes your eye health. The anti-glare coating minimizes distracting reflections and reduces the amount of harmful blue light emitted from the screen. This helps prevent eye strain, fatigue, and headaches, allowing you to work or enjoy digital content comfortably for extended periods. Easy to Apply and Remove: This monitor film features a hassle-free installation process. The electrostatic adhesion ensures a secure, bubble-free attachment to your screen without leaving any sticky residue upon removal. It's also designed for multiple applications, allowing you to easily reposition it as needed. The package includes a cleaning kit for a clean application.
