Immediate effects of coloured overlays on the reading performance of preschool children with an autism spectrum disorder using eye tracking.
Coloured overlays do not give preschoolers with autism an instant reading lift.
01Research in Context
What this study did
The team placed coloured plastic sheets over story pages. They watched preschoolers with autism and typical peers read. Eye-tracking cameras measured speed and eye jumps.
Each child tried pages with and without the tinted overlay. The test lasted minutes, not weeks.
What they found
The overlays gave no instant reading boost for either group. A few kids read a little faster, but most stayed the same. Eye movements did not change in any clear way.
How this fits with other research
Lim et al. (2016) saw the opposite. In that study, half of kids with Tourette’s and a third with autism read 15 % faster when they used the same coloured sheets.
The difference is age. The 2016 paper tested a mixed-age group, including older children. The new paper looked only at preschoolers. Little eyes may not yet show the same visual stress that older kids do.
Lemons et al. (2015) and Kovarski et al. (2019) also used eye-tracking with young children with autism. Both found small eye-movement quirks, but no magic fixes. The pattern is clear: quick lab tricks rarely create big reading jumps in preschoolers.
Why it matters
If parents ask for coloured overlays, explain that the tint is harmless but not a fast fix for three- to five-year-olds with autism. Track each child’s speed over weeks instead of minutes. If you want to try overlays, reserve them for older kids who report words “moving on the page.”

03Original abstract
BACKGROUND: Coloured overlays have often been used to improve reading performance in preschool children with an autism spectrum disorder (ASD), however, previous evidence shows conflicts in its application. AIMS: To investigate the immediate effects of coloured overlays on reading performance using eye tracking in preschool children with ASD and their typical development (TD) counterparts closely matched by chronological age. METHODS: Forty participants with ASD (n = 20) or TD (n = 20) were recruited by convenience sampling and asked to read aloud numbers randomly arranged on paper. Participants' ocular performance (fixation duration, fixation count, total visit duration), reading speed and number of errors were recorded by eye tracker and digital stopwatch respectively throughout testing with and without coloured overlays. RESULTS: The findings show that coloured overlays had no significant immediate effect in improving ocular performance and reading speed of children with ASD or TD, although individual improvements were identified in some children with ASD. CONCLUSIONS: Use of coloured overlays may not be useful to improve reading and ocular performance in children with ASD in one single occasion. The potential effect on reading ability of using coloured overlays repetitively for a longer period needs further investigation.
