Claro ScreenRuler v3
Claro Software’s Claro ScreenRuler helps you with reading by colouring (tinting) the screen or providing a horizontal reading bar. It can assist you with viewing and concentrating on text. It provides a strip across the screen in a colour of your choice and allows you to have the rest of the screen coloured and darkened out if desired. You can choose from a range of ScreenRuler modes and alter the ScreenRuler settings.
