Frameless Blackout Privacy Filter For 13.3" Widescreen Laptop, 16:9 Aspect Ratio

These filters utilize ingenious microlouver technology to deliver world-class effective privacy for laptops and monitors. Side views are "blacked out" from prying eyes while your screen remains clearly visible to straight-on views. These filters fade to black starting at the 30-degree side angle, are reversible between a glossy side and glare-reducing matte and reduce 35% of blue light transmission.
