ScreenRuler helps you with reading by colouring (tinting) the screen or providing a reading toolbar. Some people find common black-on-white text hard to read, and prefer off-white colours. ScreenRuler can provide a coloured overlay for the whole screen so everything is tinted and easier to read. You can choose any colour you like and change colour and intensity depending on the time of day, the light conditions and what you are working on. Some people find focusing on the current line of text hard, and going from one line to the next when reading even harder. ScreenRuler can give you a strip or ruler across the screen to keep your attention on the line of text you are reading. You can also make the screen outside of the strip darker to help you concentrate on the strip, and provide a tint or colour to the strip itself. ScreenRuler works with multiple monitors and any video card. It sits quietly in the system tray (Notification Area) out of the way while you work.
