Irlen Syndrome, Adult Dyslexia, and Related Disorders

The Irlen Syndrome is a syndrome that a dyslexic person may have. Because they share a lot of symptoms, this disorder is closely related to dyslexia. Furthermore, many dyslexics, in addition to having dyslexia, suffer from this syndrome.

According to study and testing, seeing a warped page of numbers, words, and musical notes can cause a variety of issues. Reading, spelling, and writing can all be affected. Math, copying skills, music reading, driving, athletic performance, computer proficiency, and comfort under fluorescent lights can all be impaired.

Irlen’s Characteristics

The printed page is perceived differently by people with this syndrome than by people with normal eyesight. If you have it, you will be forced to continually adjust to the distortions you perceive on the printed page.

As a result, you may become a slow or inefficient reader. You may also show poor comprehension because you don’t fully comprehend what you’re reading. You may also have headaches, tension, or exhaustion.

Your attention span, motivation, energy level, depth perception, handwriting, and, most importantly, your self-esteem can all be affected by this illness. Underachievers with behavioral, motivational, or attitudinal issues are sometimes described as people with this syndrome.

This syndrome is a multifaceted and complicated disorder that frequently coexists with other learning difficulties, such as dyslexia.

The First Steps

Helen Irlen, an Educational Psychologist, was the first to recognize the syndrome. This occurred in the 1980s while working with adult learners in California. She noticed that when her students utilized a colorful overlay to cover the printed page they were reading, they were able to read more easily.


If you have this illness and are dyslexic, you must use the proprietary treatment approach. You’ll need specially formulated colored overlays or colored glasses for this. These can be worn as glasses or as contact lenses. When you utilize the lenses, you’ll notice a reduction in perceptual issues, if not complete eradication.

Their program is tailored to meet the needs of persons with learning disabilities such as ADHD, autism, dyslexia, and other conditions that can make it difficult to perform well at work, in the classroom, and in social situations.


Poor reading comprehension, reading in low light, misreading words, skipping words or lines, reading slowly or hesitantly, and avoidance of reading are all indications of this illness.

A person with this illness may experience a variety of symptoms while reading, including strain, exhaustion, drowsiness, sleepiness, migraines, and nausea. While performing the work, a person may appear restless and fidgety.

When it comes to writing, you can have issues with copying words, irregular space between letters, writing uphill or downhill, and inconsistent spelling.

You may get weariness and tension while using the computer. When it comes to reading music, you could have some difficulties. You also make a lot of sloppy or thoughtless math blunders. When numbers are written in columns, they are misaligned as well.

However, one evident indication is the syndrome’s impact on depth perception. You’re clumsy and struggle with sports that need you to catch balls. You can also have difficulty judging distances.

The majority of the time, when people with dyslexia receive treatment, the intervention fails due to the presence of Irlen Syndrome. That is why, if you have dyslexia, receiving an assessment for this illness is crucial.
