If you, or someone you know, is visually impaired; or you are like me, getting weak in the eyes, then give OneLoupe a try.
OneLoupe is a software driven virtual magnifier for your PC that works just like a real magnifying glass. There is no install file to OneLoupe. Simply download and run (less than 40K file size).
Once you have OneLoupe up on the screen, you can use the following commands (in the screenshot) to manipulate how OneLoupe works. For example, when I use OneLoupe, I will use the mouse wheel to zoom in and out, will hit the letter “T” on the keyboard to minimize OneLoupe to the system tray and will use the “left-right-up-down arrow keys” on the keyboard to change the dimensions of OneLoupe.
