Have you wondered if colored lenses or overlays could help your child with dyslexia?
The quick answer is no. But keep reading to see if colored overlays might still help your struggling reader.
Dyslexia and Vision Problems
Research on dyslexia has shown that dyslexia is not caused by a problem with the eyes. Dyslexia is caused, at least in part, by a difference in how the brain processes visual information. So you can have 20/20 vision but when what the eye sees enters the nerves, the neural pathway is ‘scrambled’ or takes a detour that makes the processing of that information slower.
There are problems with the eyes, however, that can cause difficulties with reading such as visual tracking issues and light sensitivity also known as Irlen Syndrome or Meares-Irlen Syndrome.
Signs of Irlen Syndrome
Light sensitivity or Irlen Syndrome is characterized by:
Slow or inefficient reading
Difficulty reading music
Poor sports performance
Bothered by glare, fluorescent lights, bright lights, sunlight, and sometimes lights at night
People with Irlen Sydrome are prone to headaches during reading and often complain that letters on a page are blurry, moving, or disappear.
This light sensitivity can cause symptoms that look similar to dyslexia and Irlen Syndrome experts suggest that some people are incorrectly diagnosed with dyslexia when in fact, they have Irlen Syndrome.
According to the Irlen website, Irlen Syndrome Affects:
12-14% of the general population
46% of individuals with reading and learning difficulties
33% with ADHD
33% with autism
55% with head injury, concussion, or whiplash

How Colored Overlays Work
Irlen Method technology uses colored overlays and filters to improve the brain’s ability to process visual information.
In people with Irlen Syndrome, colored overlays can improve reading fluency, comfort, comprehension, attention, and concentration while reducing light sensitivity. This is not a method of reading instruction. It is a color-based technology that filters out offensive light waves, so the brain can accurately process visual information.
Getting the right color overlay
Color overlays are readily available on Amazon and in the past, I have purchased an inexpensive set to try out with my kids. I tried each color to see if there was one that they preferred. I didn’t realize that you can experiment with several colors at once. My kids were more annoyed by the overlays than anything so I never gave them another thought.
To truly determine if your child suffers from light sensitivity, or Irlen Syndrome, it is recommended that they be screened by a professional trained in the Irlen Method.
Colored lenses provided by optometrists and vision specialists to treat reading problems are not the same as the Irlen Method. These professionals do not have the correct diagnostic process for color selection and inaccurate color selection can result in worsening symptoms.
Is it Dyslexia or Irlen Syndrome?
Since many of the symptoms of Irlen Syndrome and Dyslexia can be similar, how do you know which problem you really have? Let’s define our terms.
According to the International Dyslexia Association, “Dyslexia is a language-based learning disability. Dyslexia refers to a cluster of symptoms, which result in people having difficulties with specific language skills, particularly reading. Students with dyslexia usually experience difficulties with other language skills such as spelling, writing, and pronouncing words.”
Experts agree that dyslexia is language-based, and remediation generally focuses on using a multi-sensory, structured language approach to help strengthen the brain pathways that connect speech with print. In fact, it is a myth that the telltale sign of dyslexia is seeing words backwards.
In contrast, Irlen Syndrome is a perceptual processing disorder. It is not language-based and phonics-based instruction will not help someone with Irlen Syndrome improve in the same way it will help someone with dyslexia improve their reading skills.
Irlen Syndrome is a light sensitivity, where individuals are sensitive to a specific wavelength of light and this sensitivity is what causes the physical and visual symptoms that people with Irlen Syndrome experience. People with Irlen Syndrome have difficulty reading, not because their brains have difficulty connecting the letters they see with the sounds those letters make, but because they see distortions on the printed page, or because the white background or glare hurts their eyes, gives them a headache, or makes them fall asleep when trying to read.
People with Irlen Syndrome have difficulty processing all visual information, not just words on a printed page, so they often experience difficulty with depth perception, driving, sports performance, and other areas not generally connected with dyslexia.
Should You Try Colored Overlays With Your Struggling Reader?
Our family has never benefited from using colored overlays although I have met and talked with others who have. If your child is experiencing more of the Irlen Syndrome signs and traditional Orton-Gillingham reading instruction isn’t making a big impact, I would consider contacting and Irlen profesional for an assessment.
