The syndrome was identified first by Helen Irlen, an Educational Psychologist. This happened in the 1980’s while working in California with adult-learners. She was able to observe that a number of her students can read with better ease every time they used a colored overlay to cover the printed page they are reading.
If you are a dyslexic with this condition, you would have to undergo the patented treatment-method. Here you need to use specially formulated, colored overlays or colored lenses. You can wear these as glasses or even contact lenses. Once you use the lenses, a reduction or even elimination of perceptual-difficulties is experienced.
Their program is specifically designed to fulfill the needs of people with learning difficulties, such as ADHD, autism, dyslexia, and other conditions that can interfere with sufficient functioning inside the workplace, classroom, and socially.
Some symptoms of this syndrome are poor reading comprehension, reading in dim light, misreads words, skipping of words or lines, slow or hesitant manner of reading, and avoidance of reading itself.
While reading, a person with this condition can have numerous complaints like strain, fatigue, tiredness, sleepiness, headaches, and nausea. A person may also seem restless and fidgety while doing the task.
In regards to writing, you can have some trouble copying words, unequal spacing between characters, uphill or downhill direction of writing, and inconsistent spelling of words.
When using the computer, you can also feel fatigue and strain. You may also experience some difficulty when reading music. Also, you often have sloppy or careless math mistakes. When you write numbers in columns, they are also misaligned.
One obvious symptom however is the syndrome’s effect on your depth perception. You are often clumsy and have difficulty with sports that involve catching balls. You may also have problems in judging distances.
Most of the time, when people with dyslexia undergo treatment, the intervention is not successful since there is an underlying presence of Irlen Syndrome. That is why getting an assessment for this condition is equally important when you have dyslexia.
