IRLEN syndrome, formerly known Scotopic sensitivity syndrome = SSS causes a distorted world. This person suffers from tension and fatigue. The reason is that the brain cannot process some rays of daylight and thus more centers of the brain are active than they needed to process visual stimuli. Irlen Syndrome is said to be hereditary and involves 13% of the general population. It affectsequally men and women. In addition 46% of people with dyslexia or learning difficulties, 55% of people who have suffered a stroke and 33% of people with attention deficit – hyperactivity suffer from this syndrome. The syndrome may also cause impaired vision not fully addressed by an ophthalmologist.


The 46% of individuals with reading problems, dyslexia or various training problems have the Syndrome [Irlen]. These people can be characterized or give the impression that they are individuals with poor performance,behavioral problems, concentration problems or that are not motivated for learning.


  • Slow and insufficient reading
  • Inexplicable tiredness or poor reading
  • Writing, copy

  • Mathematical concepts and use of computer

  • Those that suffer from the Irlen syndrome, usually do not make sufficient progress with instructions and therapeutic programs.

Research and Evaluation

Since 1983, surveys have shown that the right color improves reading rate, accuracy and understanding. The right filter allows the brain to record and process the exact visual information. The Irlen Method has helped hundreds of thousands of people worldwide.

Periodic re-evaluations, treatments or other interventions may be necessary to eliminate learning difficulties that may coexist.


Bothered by fluorescent lights, bright lights, shiny objects, sunlight, or night driving

Poor progress in reading, grades do not represent the effort and knowledge, the grades in the tests are lower than expected, avoid reading, or do not read for pleasure

Problems with the clarity or with stability of page printed paged or the white background influences the reading of words, numbers or music’s note. Poor speed, precision, comprehension and pleasure.

Their attention is easily extracted and they have problems beginninga exercise, remaining in a exercise, they show that they are easily and quickly tired and fast, feel concern or nervousness.

Headaches, stomachache or migraines that do not have certain medical cause, by reading,  doing the homework  or other perceptual activities.

They feel that they are exhausted, tired or feel drowsiness when they read,  study or make perceptual activities.

Inability to accurately calculate distances, proportions of space. Difficulty with escalators, stairs, in sports that are played with the ball, or driving.


  • Better comprehension

  • Increased reading speed

  • Improved precision

  • Reduction of tiredness and effort

  • Increase of motives

  • Increased self-esteem

  • Increasing performance in school (academic performance)


The Irlen method is a technique of re-establishment that uses also coloured transparencies with precision dyed filters, is worn as glasses or contact lenses in order to decrease or eliminate the perceptual disturbances and the sensitivity to light. To filter is not as the sunglass. This unique colour brings comfort without making the environment dark or coloured. An intensive diagnostic evaluation is essential in order to find the most effective chromatic filter or even combination of filters from the whole spectrum of the invisible and visible radiation. The diagnosis is made by certified Irlen screener or diagnostician.

So the radical solution of the problem is to find the correct colored filter for the individual by a certified screener or diagnostician. The symptoms stop immediately and the individual perceive the world correct. The method is applied in 42 countries of the world and is supported by scientific data.

The Irlen method does not replace the need for treatment but withdraws the obstacles that impend the learning.
