Screen enlargers are primarly for the visually impared. They work like a magnifying glass for the computer by making different sections of the screen larger to increase visibility in order to make it easier to see items on the computer. Some screen enlargers allow a person to zoom in and out on a specific section of the screen. Most operating systems today have an application in them that has the screen enlarger. For example the most current Microsoft office has a magnifying glass in the lower right corner of the screen.
