The reading bar...

Think of the reading bar as an on-screen equivalent of holding a bookmark under each line as you read. The reading bar attaches to your cursor; simply hold it under each line and move with your mouse or trackpad. Your eye will naturally track along the bar, making it easier to scan every word rather than jumping around the page. You can customise the size and colour of the reading bar to suit your preference. Use it as a dark underline, or as a colour highlight covering each line as you read.

The screen tint...

ReadingBar also includes a screen tint function, which reduces eye strain and visual stress by reducing the harsh contrast of black text on a white page. The screen tint enables you to spend more time reading before your eyes need a rest. It can turn a standard black and white page into dark grey text on a light grey background, or you can choose a custom colour—whichever is most comfortable for your eyes. If you have multiple displays, you can select which screens to tint, so you can have a tinted screen for text and a normal screen for images.
