Screen Magnification Software

Screen magnifiers do just that, magnify everything on the computer screen, including toolbars, menus, and graphics that often can’t have their font size easily increased by other means. Some also offer related tools that make the computer easier to see, like screen tinting or color inversion to reduce eyestrain, and mouse and text cursor changes to make the cursor easier to track across the screen.

Who can benefit?

  • People who are blind or have low vision
  • People who get eyestrain from looking at unfiltered computer screens

Below is an example screen magnifier used at the University of Illinois, as well as some free alternatives available to anyone. The free alternatives listed are by no means exhaustive, and many won’t have all the features available from paid programs. However, they do give a good example of the basic functionalities available, and may help determine whether it’s worth pursuing more feature-rich alternatives.
