People who have difficulties keeping their focus on the line being read find this design useful. Focus can be further confined by taping paper over the wide transparent window a 6.4 mm below the opaque part of the ruler, so that all words except the present line are completely blocked out. Plain Window Reading Rulers Plain Window Reading Rulers are the same size, price and colours as the Duo Window Reading Rulers, but with only one window and a tracking line 1 cm from the edge. They have no opaque strip in the middle. Confident readers who struggle with visual stress often prefer plain because there is no interruption to the flow of text.
