From the developer:
Very similar to Dark Screen, ssOverlay (the ss stands for Scotopic Sensitivity), places a coloured overlay onto the screen. The colour and transparency levels can be adjusted to suit the user. Everything is controlled from the icon in the Notification area of the Taskbar (where the clock sits). Clicking this icon will open the menu which allows the selection of Multi Monitor Support, and the percentage of dimming of the screen
You may want to check out more software, such as PC ScanAndSweep or Mz Vista Force, which might be similar to ssOverlay.
