What is Irlen Syndrome?

Irlen Syndrome (also referred to at times as Meares-Irlen Syndrome, Scotopic Sensitivity Syndrome, and Visual Stress) is a perceptual processing disorder. It is not an optical problem. It is a problem with the brain’s ability to process visual information.


This problem tends to run in families and is not currently identified by other standardised educational or medical tests. Irlen Syndrome has a range of symptoms and can affect many different areas, including:

  • Academic and work performance

  • Behavior

  • Attention

  • Ability to sit still

  • Concentration

Irlen syndrome can present itself differently for each individual and is often a lifetime barrier to learning and performance. If you suffer from any of the following, Irlen Syndrome might be your problem:

  • Print looks different

  • Environment looks different

  • Slow or inefficient reading

  • Poor comprehension

  • Eye strain

  • Fatigue

  • Headaches

  • Difficulty with math computation

  • Difficulty copying

  • Difficulty reading music

  • Poor sports performance

  • Poor depth-perception

  • Low motivation

  • Low self-esteem

The Irlen Method is a non-invasive patented treatment that uses precision tinted Irlen spectral filters worn as glasses or contact lenses. These selectively reduce the input of specific wavelengths of light and allow the brain to process visual information correctly, without distortions and physical/behavioural symptoms
