Irlen Centre Lancashire — What is Irlen Syndrome?

What is Irlen Syndrome?

A visual processing difficulty, often overlooked

Irlen Syndrome is a visual processing difficulty where the brain struggles to process certain light wavelengths efficiently. It is not a problem with the eyes themselves, but with how the brain processes what the eyes see. It can significantly affect reading, concentration, learning and daily life.

Irlen Syndrome affects individuals of all ages and is often found alongside dyslexia, ADHD, autism and other specific learning differences. It is estimated to affect around 15% of the general population and up to 46% of individuals with reading and learning difficulties.

The good news is that Irlen Syndrome can be significantly improved with the use of precision spectral overlays or filters — coloured lenses specifically calibrated to the individual's unique needs.
