20 Inch Privacy Screen for Monitor 16:9 - Anti Glare Blue Light Filter

In this review the 20 Inch Privacy Screen for Monitor is evaluated for office workers and anyone who uses a 20 in widescreen display. The bottom line: it is a practical privacy and eye-protection accessory that fits 16:9 screens measuring 17 7/16 x 9 13/16 in and provides clear left-right privacy while reducing blue light and glare. The single biggest reason to buy is the combination of effective side privacy and a reversible glossy or matte finish that also cuts UV and a large portion of blue light, useful in public or shared spaces.

Key Features

• Perfect fit: Designed for 20 in widescreen monitors with a 16:9 aspect ratio and the exact viewing area of 17 7/16 x 9 13/16 in, so it fits common iMac, HP and Dell displays without trimming.
• Privacy protection: Uses patented micro-louver technology to block viewing from more than about a 60 degree angle on either side, helping keep on-screen content private in public or high-traffic areas.
• Dual finish: The reversible glossy and matte surfaces let users choose a clear look or a matte option to reduce external glare depending on lighting and personal preference.
• Eye protection: Filters out 92% of UV and reduces blue light by about 65%, which can help lessen eye strain for prolonged computer use.
• Two-pack and installation options: Comes as a two-pack and includes both attachment strips and slide-mount tabs with tools and instructions to simplify installation and reduce air bubble or dust issues.
• Durable surface: Anti-glare and anti-scratch properties preserve screen appearance and extend the life of the filter in daily use.

Who It's For

This privacy filter is best for professionals who use a 20 in 16:9 monitor in shared workspaces, open offices, public terminals, or home offices where side-by-side seating makes shoulder surfing a risk. It also suits anyone who wants reduced glare and a measurable reduction in blue light to minimize eyestrain.

Those who need full 360 degree privacy or a custom-cut filter for an unusual screen size should look elsewhere, and users who prefer a permanently glossy-only finish may be better served by a different single-surface protector.
