What is Irlen Syndrome?

Irlen Syndrome affects a large portion of the population. While it is especially prevalent in students with learning and reading difficulties, it also affects a significant portion of gifted students and good readers.
It is not an optical problem. It is a problem with the ability to process visual information. Irlen syndrome affects an estimated 12-14% of the general population including gifted students and good readers.
Irlen Syndrome can affect academic performance in areas such as copying, writing, math calculations. Spelling and computer use. Attention, concentration, performance, and motivation may also be affected.
When Irlen Syndrome goes undetected, some individuals may be viewed as underachievers with behavioural, attitudinal, emotional, or motivational problems. Others may appear bright, but because they are not achieving up to their potential, they are often seen as “lazy” or as “not trying hard enough”.

The Irlen Method is non-invasive technology that uses coloured overlays and tinted lenses in the form of glasses to improve the brain’s ability to process visual information.
About the Irlen Method
Backed by over 40 years of research, Irlen is the pioneer and global leader in spectral filter colour lens technology.
Known by names, including Irlen Syndrome, visual stress, and scotopic sensitivity, the symptoms than can be helped with colour are wide-ranging and appear in many different populations, including those with migraines, brain injury concussion, ADHD, ADD, autism and learning difficulties and many other light-based difficulties by directly addressing a core problem; the brain’s inability to process visual information and specific wavelengths of light.
The Irlen Method is a straight forward solution that offers immediate results.
