Kensington iMac Privacy Screen for iMac 21.5' K50722WW

A washable, reusable adhesive makes it easy to install, detach, and reattach, with no unsightly bubbles. Limited viewing angle narrows the field of vision to +/- 30 degrees, helping keep the information on your screen private and reducing the chances of a visual data breach in the office or in public. Blue light reduction filters out harmful rays by up to 22%, easing eye strain and reducing the chances of interrupting sleep patterns. Low reflective coating reduces glare for improved clarity. Helps keep iMac screen free from scratches and damage. Includes cleaning cloth and protective case to help prevent scratches when not in use
