Privacy Screen Protector 13.3–27" Blue Light Blocking Filter

Universal Privacy Screen Protector with Blue Light Blocking — 13.3" to 27"

Keep your on-screen content confidential and protect your eyes with this snap-on privacy monitor filter. Designed for both desktop monitors and laptops, this anti-peeping screen protector narrows the visible angle to ±30°, so only the person sitting directly in front of the screen can clearly see what's displayed — making it ideal for open offices, cafés, co-working spaces, and any public setting.

Key Features

• Privacy at ±30° Viewing Angle: The screen appears dark to anyone viewing from the side, while remaining crystal clear for the direct viewer. Easily adjust privacy levels by changing your monitor's brightness.
• Blue Light & UV Reduction: Filters approximately 70% of blue light and 66% of UV light, helping to reduce eye fatigue during extended screen sessions — great for long work days or late-night use.
• Scratch & Dust Protection: The high-transparency, reinforced protective layer shields your monitor from scratches, dust, and everyday wear, extending the life of your screen.
• Tool-Free Snap-On Installation: No adhesives, no bubbles, and no tools required. Simply snap the filter onto both sides of your monitor in seconds. It's fully removable and reusable — ideal if you switch between monitors.
