Irlen Syndrome is a disorder that effects visual processing from the back of the eye to the occipital lobe in the brain. This syndrome causes individuals to experience visual distortions and is often referred to as "perceptual dyslexia". It can be a result of psychological disorders as well as be inherited, but in many instances this syndrome is developed as a result of brain surgery or traumatic brain injury. I find this interesting because i have experience severe head trauma and had brain surgery on my right temporal lobe. I always consider myself lucky that i walked out of the hospital and have had no severe after-effects considering how bad my situation was, so i found myself intruiged when reading about this. Basically, a person with this disorder is unable to read due to letters and words litterally moving about one another, struggles with depth perception, has difficulty focusing and is highly sensative to light. In some cases, individuals assume that everyone sees things the way they do and never realize they have a visual processing disorder leading to stress and fatigue.
