Irlen Syndrome is a visual perceptual problem that affects learning, concentration, reading comprehension, and productivity.

More often, Irlen Syndrome manifests itself through reading difficulties. Those affected perceive distortions while reading. Science now confirms that Irlen Syndrome is caused by an overstimulation of neurons in the brain, which in turn is provoked by some light frequencies that light-sensitive persons cannot process effectively.

In addition to producing distortions which make a text hard to read, Irlen Syndrome will also cause:

• Visual stress and fatigue after a short reading period
• Difficulties understanding what is being read
• Poor recall of what has been read
• Poor reading rate; reading is slow, choppy and full of hesitations
• Poor attention, distraction, and agitation
• Headaches and migraines
• Behaviour problems, impulsivity and irritability
