ABSTRACT:
In its broadest context, the monitor magnification device includes a monitor cover adapted to be secured over a monitor. The cover includes an internal linearly adjustable lens which is adapted to magnify the image upon the monitor.

The various components of the present invention, and the manner in which they interrelate, will be described in greater detail hereinafter.
