– The Original Plain Window Reading Ruler Overlays - Multi-Colour (Pack of 10) by Crossbow Education UK- Dyslexia Aids and Visual Stress Specialists

Great value when purchasing multiple ones. My son has visual stress and it means he has spare ones for home and school. They are thicker than the previous ones be bought and feel more sturdy. He likes the line on them for following text and keeping his place while reading. But they're also small enough to use on worksheets etc.

Perfect size and quality for students to use when reading. Helps them see the text clearer and keep their place. Delivered in a useful wallet. Good variety of colours in the pack.

I have quite a few pupils in each of my classes that find it easier to read using various different colours. These reading rulers are great as they contain all the colours I could possibly need. A little expensive but great for lots of different pupils so good value for money overall.

I find black text on a white background more difficult to read than on some other backgrounds so suspect that that there's an underlying reason for that. After reading that filters can help people with dyslexia, ADHD or Irlen's syndrome (though people disagree if that is real), I bought these to experiment and see if anything helped. Some of the filters seem a bit dark and dull to me ( pink for example ) but I have been able to find some which feel better for me and make it easier to read. The filters are not cheap but if they help with your reading then it's worth it.

Bought these to help students who struggle to read black print on white paper. One now missing from my set - given to a student when he left, it saw him through college, and is now kept in his boss' van for when he needs to read instructions. That's a recommendation!!

These are useful even for those without dyslexia but with a lack of focus when reading. It is good to have a full range of colours to experiment with which one suits the child best - only they can tell. Good price, good delivery. Very happy with this company.

Ordered these before for my daughter - make a huge difference to her. Unfortunately this batch are a noticeably different colour and don’t help her. I’ve been in email discussion with Crossbow who state “ We work closely with Professor Arnold Wilkins (the leading researcher into Visual Stress) in creating our colours. He states that a change in colour composite of up to Delta 4 is acceptable: Delta 1 – 2 is only just visible to the eye, Delta 4 is visible but within our remit and should not change the reading speed of the individual by a noticeable amount. We do mostly achieve between delta 0.5 and 2 with our colours however some may reach the 4 and as mentioned this shouldn’t affect the use of the overlay.” My daughter disagrees - she can’t use these overlays as they do not help. Fortunately she still has one from the previous order so can manage. Crossbow also suggested I purchase the multi colour pack - but I did that at the beginning and that was how she picked this colour. I don’t really know what to do now as crossbow haven’t responded to my last 2 emails. Photo of original filter on left and latest on right.

A quality product well wrapped and delivered on time
