A4 Purple Overlay

A4 overlays can be preferable to the smaller, Reading Rulers in a number of cases. In addition, it may be preferable when reading pages of music, factual information sheets etc. to be able to see the whole page. Overlays can easily be cut in half to use with smaller pages.

One side of the overlay has a matt coating which ensures maximum print clarity is retained while reflected light from the overlay surface has been significantly reduced. However, some people prefer using the gloss side of the overlay.

Coloured overlays can significantly reduce the symptoms of visual stress by filtering out the wavelengths that over-stimulate the visual cortex. The use of a coloured overlay of the correct colour can significantly increase the reading speed and comprehension for many children and adults. It can also make reading a far more pleasurable experience and eliminate headaches and migraines (see below).

Visual Stress 


Visual Stress is a reality for about 20% of the population. It can cause headaches, migraines, reading discomfort and distortion of text that can vary from mild to so severe that reading is seriously impaired or even prevented. Therefore, a significant proportion of the population would benefit from the use of a coloured overlay.

Visual Stress is often experienced by people with dyslexia (perceptual dyslexia), but is a separate and distinct condition. Apparent movement and distortion of text, headaches and sore eyes are common symptoms of visual stress.
The effects of Visual Stress can often be easily and inexpensively remedied by the use of coloured overlays. They have been found to help many adults and children with specific learning difficulties such as dyslexia and autism. However, they can also help children and adults who have to do a lot of reading, particularly if this is black ink on white paper.
Research and experience has proved conclusively that the use of a coloured overlay of the correct colour can significantly increase the reading speed and comprehension for many children and adults. It can also make reading a far more pleasurable experience and eliminate headaches and migraines.

By experimenting with different combinations it is usually possible to meet individual needs, although there may be a small number of individuals who would benefit from a tint that cannot be produced.

The Difference an Overlay can make:

 

As part of my dyslexia assessment I test the use of coloured overlays with my clients. I always ask whether teach colour in turn makes the print easier to see, harder to see or makes no difference when compared with words written in black ink on a white background:

One little boy of eight said that none of the overlays made any difference until we tried the green. He immediately did a double take and ran to show his mum. He said, ‘Look mum, without the green all of the words stick together, but with the green there are gaps!” And all this time he had had to work out when one word ended and the next began!

One woman was amazed when we tried the pink overlay as without it the lines of text moved up and down, with the overlay they stayed still and the difference in her ability to read the page of text was significant.

 

Additional Information: 

 

Many children with specific learning difficulties such as dyslexia and autistic spectrum disorders have specific difficulties with reading, spelling and writing that have a negative impact on their performance in the classroom and their ability to learn.

The British Dyslexia Association says that around 35-40% of people with dyslexic difficulties are estimated to experience visual disturbance or discomfort when reading print.

These children and adults may experience one or several of the following:

  • Blurred/fuzzy letters or words which go out of focus.
  • Letters which move, shimmer, whirl or move off the pager or present with back to front appearance.
  • Headaches or migraines as a result of reading.
  • Find whiteboards difficult to read or copy from
  • Constantly rub or blink their eyes to help bring the print back into focus
  • Find it easier to read large, widely spaced print, than small and crowded.
  • Difficulty with tracking across the page, omitting words or lines of text.
  • Upset by glare on the page or oversensitive to bright lights. Students in school or adults in offices will find fluorescent  lights particularly difficult.

All of this makes reading a difficult activity. Unfortunately, children and indeed sometimes adults don’t tell us that they are experiencing these difficulties as they think it is the same for everyone.

This condition may be due to a visual-perceptual disorder or simply Visual Stress. In many cases, this particular condition can be remedied by a very simple and inexpensive intervention: reading through a coloured overlay that changes the colour of the page.

Coloured Overlays or Tinted Lenses?

In some cases, if the use of a coloured overlay is having a significant impact on the reading ability of a person and therefore a thorough assessment by a specialist optometrist or Irlen’s Assessor is recommended as the use of tinted lenses may be preferable to intervention with coloured overlays. For example, overlays may reduce or eliminate the effects of glare on a printed page in a classroom, but the writing on the whiteboard at the front or the posters on the wall may still be causing significant problems. However, as children get older they often become increasingly self-conscious about their lenses and may "forget" to wear them. This is up to each individual.
