Varakari's Vision Log Tool
Varakari's Vision Log Tool is a measurement program available for Windows.
It lets users easily measure centimeters using a target in the middle of the screen, and keep a graph of progress over time, saved as files on the computer.
It is available as freeware for anyone to download.
If you cannot run the program but still want to use the target offered in the program, to the right is a 16:9 image of the target, centered in the middle of the screen. Download the image and full screen it in a photo viewing program.
