The Kensington GlareMaster Premium Plus Filter for 19 to 21" Monitors lets you work in peace. Coated, optical-quality glass narrows the viewing angle of your monitor, making it virtually impossible for neighbors and passersby to catch a glimpse of your private e-mails and account information. You also have the added benefit of glare reduction, helping keep your eyes healthy when spending long hours in front of the screen. monitor filter antiglare filter computer screen filter 55009433
