Welcome to the Irlen Dyslexia Clinic – Ipswich & Surrounding Districts. (NDIS Reg. 4050018380)

Servicing: Ipswich & Surrounding Regions, Gold Coast & Hinterland, and the Regional Shires of Toowoomba, Quilpi, Bulloo, Paroo, Baloone Goondiwindi, Murweh, Maranoa, Western Downs, Southern Downs, Western Downs, Scenic Rim & Lockyer Valley.

The Clinic specialises in assessing children and adults for the visual processing disorder – Irlen Syndrome/Scotopic Sensitivity Syndrome (SSS), also known as Visual Perceptual Dyslexia or Visual Dyslexia, as well as Visual Stress & Light Sensitivity issues.


It is not related to eyesight but instead is related to the vision system. In some people, light interferes with the brain’s ability to process visual information. This is sometimes referred to as “visual perceptual difficulties” or “visual processing difficulties”. Research tells us that around 15% of the general population (and 50% of the reading disabled population) have moderate to severe problems with print movement, and environmental distortions. (See our video). This can often be accompanied issues such as; eyestrain, focusing difficulties, light sensitivity, headaches or migraines, depth perception issues, clumsiness, inefficient reading, poor spelling, reluctance to write, behavioural problems, frustration, low self-esteem, anxiety and work avoidance.

What is Irlen Syndrome / SSS?

Irlen Syndrome, also known as Meares-Irlen Syndrome, Scotopic Sensitivity Syndrome (SSS) or Visual Stress, is a visual processing dysfunction which affects approximately 10 – 20% of the population, it is not an optical problem but a problem with how the brain processes visual information it receives from the printed page and environment.

Irlen Syndrome / SSS is a light sensitivity condition which cannot be tested or identified through standard psychological, educational, medical or optometric testing, but it may co-exist with optical problems.

Assessments for this brain processing dysfunction can only be carried out by certified Irlen Syndrome Diagnosticians, trained in the Irlen Method. Optometrists are unable to treat this condition.


You may like to choose an appropriate Irlen Syndrome / Scotopic Sensitivity Syndrome self-test to determine whether this condition may be contributing to you or a member of your families’ perceptual difficulties.

You can complete the self-test online with the option to print once completed.

In completing the self test, If you find three or more indicators are present you should contact the Irlen Dyslexia Clinic – Ipswich & Surrounding Regions to arrange an assessment.


People with Irlen Syndrome/SSS can have difficulty with one or more of the following:
