VistaShades is an application that allows you to adjust the level of brightness on your screen to protect your eyes.

If you're running Windows on an iMac, you may find the screen too bright, even when turning the brightness all the way down using the BootCamp controls.

I always use the excellent Mac program Shades when running Leopard on my iMac, but I was frustrated by the lack of a similar program when running Windows, so I wrote VistaShades to do something similar.
