Irlen Syndrome (also referred to at times as Meares-Irlen Syndrome, Scotopic Sensitivity Syndrome ‘SSS’ and Visual Stress) is a perceptual processing disorder caused by the brain’s inability to process specific wavelengths of light. It affects adults and children.
It is not about the eyes. It is about the brain and how it handles visual information. This problem is often inherited but can be also be caused by other factors. Certain medical conditions, illnesses and concussions all can trigger Irlen Syndrome.
It is not currently identified by other standardized educational or medical tests.
Irlen Syndrome affects 14% of the over-all population.
