The space between the lines indicates what will be in acceptable focus at a given aperture. So if the space between the two 11 marks spans 3 to 5 (screw Nikon's silly backward focusing) meters, that means things will be focus from 3 to 5 meters. In the picture, at f/22, everything is in focus past around 4 meters, because the space between the lines contains the infinity mark.
Extra fun fact: The little white dot there is probably an infrared mark. If shooting IR, focus normally, and then change the focus so that the dot marks the correctly focused point, not the line normally used. This compensates for the different wavelength of IR light or some shit like that.
