What is Irlen Syndrome / Scotopic Sensitivity Syndrome (SSS)?

brainsIrlen Syndrome, also known as Meares-Irlen Syndrome, Scotopic Sensitivity Syndrome (SSS) or Visual Stress, is a visual processing dysfunction. It is not an optical problem, it is a problem associated with how the brain processes the visual information it receives from the printed page and the environment.

Our eyes transmit approximately 70% of the information we receive and this information must be interpreted correctly by the brain. For those with Irlen Syndrome / SSS their brain processes visual information differently and this can cause difficulties in a person’s general ability to function; specifically when processing, interpreting and interacting with their environment.

Irlen Syndrome is a genetic condition which affects both adults and children. It can contribute to difficulties with:

  • Academic and work performance
  • Concentration
  • Behaviour

This condition affects each individual differently and can interfere with a variety of activities. It can create a lifetime barrier to learning and limit a person's real potential.

Irlen Syndrome / SSS CANNOT be identified through standard psychological, educational, medical or optometric testing, but it may coexist with optical problems.
