About Irlen.wiki

From Irlen.wiki, an independent record of the Irlen Institute, its colored overlays and filters, and what researchers say

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

In brief: Irlen.wiki is an independent, sourced reference on the Irlen Institute, the Irlen Method and the scientific assessment of Irlen syndrome. It is not the Institute’s website and does not sell anything or give medical or educational advice.

A note on independence: Irlen.wiki is an independent record compiled from irlen.com, irlensyndrome.org, public records and published research. It is not operated by the Irlen Institute, sells nothing and gives no medical or educational advice. The Institute’s statements are attributed to it and shown beside independent assessments. Sourcing rules: editorial policy.

Who writes this wiki?

Pages are written by the Irlen Wiki editorial team from material anyone can check: the Institute’s and foundation’s own pages, the Google Business Profile, the patent record, professional statements, peer-reviewed studies indexed in PubMed, press reports and general encyclopedia articles. No one at the Institute is presented as having reviewed these pages.

What does this wiki cover?

The Institute (history, founder, location, online presence), its products and process, the related foundation, the patent, the claims it makes about reading, headaches, ADHD, autism and head injury, and the independent assessment of those claims, plus two original data pages.

What does this wiki not do?

It does not recommend for or against any assessment or product.
It does not present the Institute’s claims as established fact.
It does not publish client photos or personal stories.
It does not link to or promote any practitioner.

What is still unverified?

These questions are open and nothing about them is stated as fact on this site:

The Institute’s legal entity name; the foundation’s board page names Perceptual Development Corporation, but a state filing was not checked.
Which of the Institute’s differing figures (44 or 46 countries; 54, 100 or 200 studies) is current.
The television appearances the Institute lists, which were not reviewed episode by episode.
Whether the LinkedIn and X accounts using the Irlen name belong to the Institute.
When the foundation adopted its current name: its pages say 2014 and the start of 2015.

How do I report an error?

Errors can be checked against the bibliography of sources; every page is a snapshot dated 9 November 2026. Appointments, prices and contact details should be confirmed with the Institute at (562) 496-2550. Corrections are recorded on the history page.
