“…Overlays have also been shown to benefit sentence comprehension and reading accuracy (Williams et al. , 1992; Robinson and Foreman, 1999; Robinson and Conway, 2000). In addition, coloured overlays and tints have been shown to significantly reduce the symptoms of migraine.…”

“…Dyslexic readers show up to a 25% advantage in reading speed when they read a text with a coloured overlay of their choice (Tyrrell et al, 1995;Wilkins et al, 1996;Evans et al, 1999;Wilkins, 2002).

Two methods of assessing candidates for coloured overlays were compared with the aim of determining which method had the most practical utility. 58 adults were assessed as potential candidates for coloured overlays, using two methods; a questionnaire which identified self reported previous symptoms, and a measure of perceptual distortions immediately prior to testing.Participants were classified as normal, Meares-Irlen sensitive, and borderline sensitive. Reading speed was measured with and without coloured overlays, using the Wilkins Rate of Reading Test and the change in speed was calculated. Participants classified as normal did not show any significant benefit from reading with an overlay. In contrast, a significant reading advantage was found for the borderline and Meares-Irlen participants. Current symptom rating was found to be a significant predictor of the change in reading speed, however the previous symptom rating was not found to be a reliable predictor. These data indicate that the assessment of perceptual distortions immediately prior to measuring colour preference and reading speed is the most meaningful method of assessing pattern glare and determining the utility of coloured overlays.3

“…Most studies of visual stress have focused on children; few have examined this phenomenon in adults. Robinson and Conway (2000) reported on a small-scale study that found benefits of Irlen filters in adults who experienced visual stress. Evans and Joseph (2002) carried out a more extensive study with 113 unselected university students who were assessed using Intuitive Overlays (I.O.O Marketing, London).…”

Visual stress in adults with and without dyslexia

The relationship between dyslexia and visual stress (sometimes known as MearesIrlen syndrome) is uncertain. While some theorists have hypothesised an aetiological link between the two conditions, mediated by the magnocellular visual system, at the present time the predominant theories of dyslexia and visual stress see them as distinct, unrelated conditions, a view that has received some support from studies with children. Studies of visual stress in adults are rare, yet recent reports of a high incidence of this phenomenon amongst university students with diagnosed dyslexia call for further investigation of the issue. This study sought to clarify the relationship between visual stress and dyslexia by comparing the reading performance of dyslexic and non-dyslexic adults with, and without, colour. Degree of susceptibility to visual stress was determined by means of a symptom rating scale. Optimal colour was determined using an Intuitive Colorimeter, which was also employed to assess reading speed under the two experimental conditions. Only the dyslexic students with high visual stress showed significant gains in reading speed when using optimal colour. The use of response to treatment (rather than symptomatology) as a diagnostic criterion for visual stress is questioned, especially when applied to adults, as this may give misleading findings. On the basis of reported symptomatology, students who experience high levels of visual stress are more likely to show improvements in reading rate with optimal colour if they also have dyslexia than if they do not have dyslexia. Although not establishing an aetiological link, these findings imply an interaction between the two conditions with major implications for theory, diagnosis and treatment.The view that visual factors are involved in dyslexia has a long and controversial history. The current predominant theory -which is so well supported that it could be said to have acquired the status of orthodoxy -is that dyslexia is caused by a genetically-based anomaly in neurological systems sub-serving phonological processing (see
