Differences between the Duo Window Rulers and the Plain Window Rulers:

Duo Window Reading Rulers are divided into a narrow reading window and a wide reading window by an opaque strip.  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 quarter of an inch below the opaque part of the ruler, so that all words except the present line are completely blocked.

gloss and matt side of reading ruler

Plain Window Reading Rulers are the same size and colours as the Duo Window Reading Rulers, but with only one window and a tracking line half an inch (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.

Winner of Education Resources Awards SEN Resource of the Year 2014.

Our current batch of reading rulers and overlays was printed while the "BDA Assured" scheme was running and carries the BDA Assured badge. This was a programme run by the BDA from 2019-2021 which gave the “BDA Assured” badge to resources that were recognised by the British Dyslexia Association as being helpful to people with dyslexia.  During that time, Crossbow reading rulers and coloured overlays were part of the scheme.  This programme has now been discontinued, and will be replaced by a new page of useful resources.

5.0 out of 5 stars Easy on the eyes.  
"I’ve purchased cheaper version of these filters, but they had distortions in the plastic and small scratches.
These filters by Crossbow do not have any distortions and are a lot easier to read through, that is the aim after all, to make it easier to read. I now read a lot longer before getting tired eyes. Well worth getting the pack rather than individual filters."
