Eye Follows Line
In making sense of what we see, our eyes first seek lines, and then they follow them. This allows us to see outlines and distinguish shapes.
The lines that our eyes follow can be very tenuous, dotted, vague and otherwise not easy to identify. Nevertheless, our eyes will do their best to follow the line to see where it goes.
Eyes will follow all kinds of line, including ones which are straight, curved, zigzag, and interrupted.
In a photography, a common device is a 'leading line' which is intended to lead the eye into the picture.

Lines can have several functions that helps the viewer make sense of what they are seeing, including:
When creating images or graphics, make sure there are clear lines for the viewer to follow in quickly and easily distinguishing key objects. Use lines also to guide the viewer around the image.
