OneLoupe is a small and free Screen Magnifying software which can magnify parts of the screen. It is quite useful for people who have weak eyes or some sort of visual impairment. You can also use it to magnify photos, drawings so that you can inspect it closely.

The program requires no installation and can be launched directly by executing the application file. You can then click anywhere on the screen and the part will be magnified. While it is active, you can zoom in or out with the mouse wheel or you can also change the magnifier window area by using the arrow keys. If you want, you can also take a bitmap screenshot of the magnified area.

The program is very small in size and can be very helpful during presentation also. It is a freeware and runs on Windows.
