There has been a surprising amount of scientific research around this issue, but in brief, there’s a reason here rooted in human physiology: when you read a block of text, you are not consciously moving your eyes from word to word like you’re dragging a mouse cursor, repositioning continuously. Human eyes reading text move in quick bursts of rotation called “saccades”. In order to quickly and accurately move from one line of text to another, the start of the next line needs to be clearly visible in the reader’s peripheral vision in order for them to accurately target it.
