Irlen Syndrome is a perceptual processing disorder, and is sometimes confused as an optical disorder. The disorder is described as an inability to process visual information. This disorder is not currently identified by other standardized education or medical tests. Ultimately this disorder is an extreme light sensitive, and can affect academic and work performance, behavior, ability to sit still, and concentration. An example of this is trying to read a book, where the words start to become blurry because of the light bouncing off the page. The problem can manifest differently in each individual, and doesn’t have any known cure.
