Irlen Syndrome – Is There an App for That???

Recently I had the opportunity to be trained as an Irlen Screener by Irlen Diagnostician, Judy Palapala of the Irlen Clinic of the Twin Cities. Having worked with both students and adults who have symptoms of the Irlen Syndrome, also known as Scotopic Sensitivity Syndrome (SSS), I wanted to be able to better assess their needs and provide them other options to help them with reading as well as vocational tasks.

So what is Irlen Syndrome? A visual perceptual syndrome that can include any or all of these symptoms:

• Light sensitivity
• Inefficient reading
• Slow reading rate
• Attention deficit
• Strain or fatigue when reading
• Poor depth perception

Individuals with Irlen Syndrome often don’t recognize that their symptoms if they have had them since birth. Since they have always seen things in a different manner, whether distorted or experienced fatigue when reading they often don’t recognize that reading could be improvied. Applying color filters for those with Irlen Syndrome can normalize light perceived and reduce the symptoms of discomfort, inefficiency, fatigue or inattentiveness to mention a few. Like the symptoms for each individual, the effect of colored filters can differ. Irlen Method of intervention is a researched based intervention ¹ that can help some with the perceptual disorder.

What is the incidence of the disorder and who does it help?

• Prevalence is 14-16 % of the general population
• Estimation that 46% of those with reading problems, dyslexia, ADD or LD have some level of Irlen Syndrome
• Other diagnoses as TBI, CP, ASD or Light Induce Epilepsy can have Irlen Syndrome¹

How do you know if you have Irlen Syndrome?

• Use one of Irlen’s self assessment tools to determine if you would benefit from screening by a Irlen certified screener or evaluator
• Certified Irlen screeners and evaluators can be found at Irlen.com

So, is there an app that supports Irlen Syndrome?

No app currently is available specifically for Irlen Syndrome, however there are apps and methods to apply the concepts of using colored filters once a color is identified that improved reading or helps with light sensitivities that for some individuals with Irlen Syndrome.

Here are some methods to help apply the color filter solutions and apps for those that are found to benefit from use of color filters:

1. Applying Irlen color filters over the top of an iPad, iPad Mini or even an iPhone can be done without affecting the touch capabilities of a capacitive screen. This provides the chosen color applied to all environments on the iOS device. Here are a couple of trials that worked using specific cases with iOS devices:
   • A color filter neatly cut to the size of the screen of an iPhone using an incase® iPhone 5 protective case worked well. Below a purple colored  filter cut to size was applied.

• Cutting a colored filter to fit under a case, such as the Otterbox® protective case also provided the color filter effects on an iPad. (Note: I trialed inexpensive colored, transparent plastic dividers which produced some minor distortions when directly on the screen – not recommended.)

Note: The above screens with color filters may not appear to work for you but what might work for one person is not correct for another!

2. Specific iOS reading apps provide back ground color options which can customize the background by chosing a color from the full color spectrum palate.

Apps that provide customizable, full color palate choices (as in above image) that can be matched to the specific Irlen filter color determined after screening for students or clients:

• Voice Dream Reader app
• AppWriter app
• iRead & Write app

Other apps that provide some color background choices but not customization:

1. Read2Go app
2. ZoomReader app (contrast colors only)

Other solutions that can be applied to an iOS device to help with light sensitivities can include:

• The iOS Invert Color setting provides one color change to reduce the contrast which can be helpful but is not customizable.
• Dimming the screen or brightness on an iOS using the Settings>Brightness & Wallpaper can allow customization of the brightness on an iPhone, iPod Touch or iPad screen.
• Applying a glare reducing screen or privacy screen (typically gray) can also help for those who need a dimmer screen.
