Irlen Syndrome is a visual processing problem which appears to be caused by a defect in one of the visual pathways that carries messages from the eye to the brain. This defect causes a timing fault in processing visual information. It is as if the brain was a radio and the frequency selector was not quite on the station so that static interfered with the reception.
Irlen Syndrome cannot be identified through standard psychological, educational or optometric testing. It is not an ophthalmological or optometric problem, but may coexist with it.
Irlen Syndrome can affect both adults and children, manifesting itself differently for each individual, and interfering with a range of activities which can be a lifetime barrier to learning.
Irlen Syndrome is different from Dyslexia, and some researchers have labelled the Irlen symptoms as Visual Dyslexia.
The Irlen Method has been used for almost 30 years to identify and help people with Irlen Syndrome. The Irlen Method determines which coloured overlays and precision-tinted filters produce the most effective elimination of symptoms.
