Key Professional Features

• Visual Data Security: By narrowing the effective viewing angle to 60 degrees (30 degrees from center), this filter ensures that colleagues or customers standing to your side see only a darkened screen, while you maintain full visibility.

• Anti-Glare Surface: The matte side of the filter is engineered to scatter light and reduce reflections from overhead office lights, making it ideal for workstations located directly under bright bulbs or near windows.

• Eye Fatigue Reduction: Prolonged monitor use can lead to digital eye strain. This filter limits the transmission of harmful blue light, helping to protect your vision during long work shifts.

• Physical Guard: Beyond privacy, the 3H hardness rating provides a physical barrier against dust, fingerprints, and accidental scratches on your expensive monitor panel.

• Universal Desktop Mounting: Comes with two installation options: permanent adhesive strips for a clean look, or slide-mount tabs that allow you to easily remove the filter for collaborative sessions.

Important Usage Notes

[!IMPORTANT]

Measurement Criticality: Most modern 21.5" monitors are "widescreen" (16:9), measuring roughly $476 \times 268\text{mm}$. This specific filter is 397 x 302mm, which is much taller. Please measure your screen's width and height in millimeters to confirm it matches these specific dimensions before purchasing.

• Brightness Note: The privacy layer will slightly darken your display. You may need to adjust your monitor's brightness settings (OSD) to compensate for the light absorption of the microlouver layer.

• Maintenance: Clean the filter using only a soft, damp, lint-free cloth. Do not use chemical sprays as they may damage the privacy coating.
