We measured the increase in reading speed afforded by two currently available systems of coloured overlays: the "Intuitive Overlays," which provide a choice of 30 colours, and the "Eye Level Reading Rulers," which provide a choice of 5. Forty-eight pupils from a local authority primary school who reported experiencing symptoms of visual stress…

When groups of children were given a test of visual performance designed to measure their dark interval threshold, differences were found between boys and girls and differences were found indicating that those children who had a moderate threshold showed superior reading ability. (MKM)

States that 46 children aged 12-16 were shown a page of meaningless text covered with plastic overlays, including 7 that were various colors and 1 that was clear. Explains that each child selected the overlay that made reading easiest. Notes that children who read with a colored overlay complained of visual discomfort when they read without the…

Concludes that skilled adult readers may use the meanings of words ahead of fixation to enrich their interpretation of a text or use those words more simply as markers to guide further eye movements to the location of the next useful fixation. (FL)

Indicates a reasonable range of individual differences in the dark interval threshold (DIT). Reveals a significant interaction between DIT and illumination level in their effect on reading accuracy. Finds that children with a short DIT read more accurately in high rather than low illumination and that this performance was reversed for long DIT…
