Bibliography by the numbers

Researched and compiled by the Irlen Wiki editorial team · First published 9 November 2026 · Revised 9 November 2026

In brief: The Irlen Institute’s bibliography listed 93 entries (91 distinct works) from 1980 to 2026 on 9 November 2026; 22 involve G. L. Robinson, and major negative studies are not listed.^[1][6]

Method

The Irlen Institute publishes a Bibliography of Research. On 9 November 2026 this reference counted every entry on that page, recording the section it appears under, its year, its first author and whether it repeats an earlier entry.^[1] The counts describe the list the Institute chose to publish; they do not grade the studies.

Size

The page lists 93 entries. Two are repeated, a 1988 clinical study by Whiting and Robinson and a 2024 paper by Tosta and colleagues, so there are 91 distinct works.^[1] The Institute’s other pages refer to more than 54 peer-reviewed papers, more than 100 peer-reviewed supportive studies and more than 200 studies in total.^[2][3]

By section

Almost half the entries sit under “Additional Research.” The nine international publications are German- and French-language items, mostly from Switzerland, including professional articles and a teacher-training dissertation.^[1]

By decade

The earliest entry is Olive Meares’s 1980 paper and the latest is dated 2026. Twenty-four entries predate 2000 and 14 are from 2020 or later.^[1]

Authors

Australian researcher G. L. Robinson appears on 22 entries, nearly a quarter of the list. Helen Irlen appears on five, and Sandra Tosta, described by the foundation as head of research for the company at the Institute’s headquarters, on seven.^[1][4] A. J. Wilkins, who researches visual stress outside the Irlen system, appears on 12.^[1][5]

What kinds of items are listed

Besides journal articles, the list includes conference papers, a grant report, a U.S. Navy case-study report, a letter to the editor of The New England Journal of Medicine, book chapters and a dissertation.^[1]

What is not listed

The bibliography does not include the 2011 randomized study in Pediatrics that found no immediate reading benefit from Irlen overlays, the 2019 systematic review that found a lack of evidence, or the joint statements of pediatric and ophthalmology bodies.^[1][6][7][8] Readers comparing the evidence should consult those alongside the Institute’s list; see scientific assessment.
