Virtual Magnifying Glass is designed for the visually impaired and others who need to magnify part of the computer display. Unlike most similar programs, it does not open a separate program window for the magnification but instead puts a movable magnifying glass[1] on the screen.
Virtual Magnifying Glass works on a variety of platforms (Windows, Linux, FreeBSD, Mac OS) due to being developed with the Free Pascal compiler. There is no charge for the software.[2]
