What is Irlen Syndrome?

People with Irlen Syndrome (Scotopic Sensitivity) have problems with visual perception. It is the brain that interprets the visual information which is then seen by the individual.
Research indicates that 12-15% of the population suffers from Irlen Syndrome. Many people will only experience slight problems, others may find it hard to learn and study.

Reading may be a problem due to the print on the page being distorted the longer they read. They experience tiredness and/or eye strain, and the eyes may become itchy or watery. These problems may generate headaches, or in severe cases, nausea. Also, computers and bright lighting conditions, such as fluorescent lighting, may be uncomfortable for them to work or study under.

Irlen Syndrome can be associated with other learning problems such as dyslexia or ADD/HD. Many people who have dyslexia may also be suffering from Irlen Syndrome.

What are the symptoms?
