Kensington's Anti-Glare and Blue Light Reduction Filters are ideal for working and learning from home, where rooms don't always have ideal lighting for working in front of a computer. These filters reduce harmful blue light by up to 43 Percent and feature an antimicrobial coating (matte side only) that inhibits bacteria growth by up to 99 Percent (tested to JIS Z 2801 : 2010E for Escherichia coli and Staphylococcus aureus). An innovative anti-glare coating (matte side only) reduces reflection and improves clarity. Seamless attachment makes installation and removal quick and easy. Touch and pen enabled, you can use your device just as you would without the filter. Includes cleaning cloth.
