Irlen Syndrome (likewise described at times as Meares-Irlen Syndrome, Scotopic Sensitivity Syndrome, and Visual Stress) is a perceptual processing disorder. It is not an optical problem.  Dyslexic Type Problems admin 2014-10-16T21:36:21+00:00. Dyslexia and Irlen Syndrome are different conditions. Dyslexia is a language processing problem which makes it difficult for people to access text. Irlen Syndrome is a perceptual processing problem which makes it difficult to access print. The two problems may exist separately or co-exist. Sometimes it may appear that someone has dyslexia when in fact they have Irlen Syndrome. Reading difficulties related to Irlen Syndrome cannot be explained by phonetic deficits or by a weak sight vocabulary. Problems most often occur under conditions of bright lighting, fluorescent lighting, black/white contrast, and continued performance. Individuals with Irlen Syndrome have difficulty reading print, numbers or musical notes because the print is not clear or stable. Problems may include print that shifts, shakes, blurs, moves, runs together, disappears or becomes difficult to perceive. Individuals with Irlen syndrome see the printed page differently. Many do not realize their page is different. Irlen syndrome prevents many people from reading effectively and efficiently. Irlen Syndrome, also known as Scotopic Sensitivity System (SSS) is a type of visual perceptual problem. It is not an optical problem. It is a problem with how the nervous system encodes and decodes visual information Irlen Syndrome. Irlen Syndrome is a specific type of perceptual difference that affects the way the brain processes visual information. It is not an optical problem. For those with Irlen Syndrome, the brain is unable to process full spectral light. This can result in: 1  A range of distortions in the environment. 2  A range of distortions on the printed page. 3  physical and behavioural symptoms. Irlen Syndrome, also known as, Scotopic Sensitivity Syndrome (SSS) is a type of visual perceptual problem. It is not an optical problem. It is a problem with how the nervous system encodes and decodes visual information.  Scotopic sensitivity syndrome (SSS), also known as Visual Stress, Irlen Syndrome, and Asfedia, is a condition relating to the interaction of the central nervous system and the eyes at a physiological level with light. There is evidence that the underlying symptoms associated with specifically Meares Irlen Syndrome, are related to identifiable vision anomalies, e.g., accommodative, binocular, and ocular motor dysfunctions, in many patients seeking help from coloured lenses. A: The Irlen Method corrects reading problems that are a result of a processing problem called Irlen Syndrome, and not a vision problem. This type of reading problem is result of the brain’s inability to accurately understand and process visual information. Individuals with Irlen Syndrome have difficulty reading print, numbers or musical notes because the print is not clear or stable. Problems may include print that shifts, shakes, blurs, moves, runs together, disappears or becomes difficult to perceive. Meares-Irlen Syndrome. Meares – Irlen Syndrome is a form of visual stress which leads to difficulties with fine vision tasks such as reading. This eye condition was identified in 1980 by an American psychologist and although the condition is not yet fully understood, it is known to affect reading ability.
