Protect Your Privacy The privacy screen protector for desktop monitors is a great investment if you want to protect your privacy. It is a convenient and cost-effective way to keep your classified information, intellectual property or any other important data you wish to keep protected. You can have a peace of mind while working in the office or public environments because you know your screen is protected with the 30+/- degree privacy viewing angle. The cutout on the top corner of the privacy screen makes it easy to remove for sharing content with trusted audiences or switching between finishes. Blue Light Reduction With working from home becoming more prominent and screen time on the rise, reducing blue light exposure is important. The monitor privacy film is designed to filter blue light (390nm~480 wavelength) and reduce digital eye strain. Antimicrobial Protection Our privacy screens feature an anti-microbial coating on the matte-side of the filter. Embedded antimicrobial technology provides protection against bacterial microbes by continuously eliminating up to 99.99% of certain surface bacteria. Antimicrobial screen protectors are ideal for environments where disinfection is important.
